Toward food safety-driven process design: a systematic review and research agenda.

Process design strategies are important to prevent or reduce food safety risks in production systems. In this sense, the Codex Alimentarius presents a set of principles for good hygiene practices to guide food producers. However, studies in food safety often focus on analyzing and controlling implemented production processes without a policy of designing them with a preventive logic, leading to resource misallocation and noncompliance. This study aims to gather and analyze techniques, drivers, challenges, and research opportunities for food safety-driven process design. A systematic literature review was carried out following three steps: (i) Data collection, including 52 studies; (ii) Bibliometric analysis; and (iii) Content analysis, identifying techniques, drivers, challenges, and research opportunities. Three main themes in the subject were identified: process assessment models, risk assessment, and whole-chain traceability. Eleven design techniques were identified and compared according to their typology, structure, and coverage of themes addressed by the Codex Alimentarius. There is a gap in techniques addressing employee competence and personal hygiene. We suggest developing a tool encompassing the Codex Alimentarius good hygiene practices themes in process design to guide food safety-driven process development.

Urinary tract infection among pregnant Jordanian women: role of hygiene and sexual practices.

PURPOSE: The purpose of this study was to examine the association between hygiene and sexual practices and the incidence of urinary tract infection (UTI) among Jordanian pregnant women. METHODS: The cross-sectional data were collected using self- administered survey from October 2018 to January 2019 in central Jordan. A total of 200 pregnant women completed the survey. All of them were married and aged between 18 and 45 years (M = 27.45; SD = 6.06). The measures used were demographics, social, hygiene and sexual practices. RESULTS: A significant association was found between the incidence of UTI and the educational level of husbands (p = 0.05), history of UTI in previous pregnancies (p = 0.02) and being in the second trimester of pregnancy (p = 0.02). Their sexual and hygiene practices also were significantly associated with the incidence of UTI. CONCLUSION: History of UTI in previous pregnancies, hygiene and sexual practices are associated with increased incidence of UTI among Jordanian pregnant women. Appropriate strategies and techniques to promote health and preventive behaviors for pregnant women with UTI should be provided to improve the quality of life among pregnant women and reduces economic burdens on health care system.

Hygiene practice and diarrhea prevalence among underfive children in Myanmar: a cross-sectional study.

BACKGROUND: Over 1.7 billion instances of diarrheal illness in children are reported worldwide yearly. Diarrhea was a major cause of death in children, accounting for 9% of all global under-five child deaths in 2021. The objective of this study was to identify the association between hygiene practices and childhood diarrhea among under-five children in Myanmar. METHOD: This cross-sectional study was conducted in 16 townships from 8 states and regions of Myanmar. 1207 children between the ages of 6 and 59 months were recruited by multistage random sampling. Data were collected with a preformed questionnaire after participants provided consent. Multiple logistic regressions were administered to determine the factors associated with childhood diarrhea. RESULT: This study found that 86 (7.13%) under-five children experienced diarrhea disease. This study identified that children receiving limited hygiene services were 2.85 times (AOR = 2.85, 95% CI: 1.31 to 6.21; p value 0.01) and children without hygiene services were 2.63 times (AOR = 2.63, 95% CI: 1.42 to 4.89; p value 0.01) more likely to have diarrhea disease than those with basic hygiene services. Other factors associated with diarrhea included: fathers who washed their hands less than four steps (AOR = 2.20, 95% CI: 1.29 to 3.74; p value 0.01), families taking more than 15 min to collect water (AOR = 1.77, 95% CI: 1.06 to 2.97; p value 0.03), families sharing toilet usage (AOR = 2.00, 95% CI: 1.15 to 3.48; p value 0.01), mother's inadequate and problematic hygiene promotion health literacy (AOR = 2.20, 95% CI: 1.24 to 3.90; p value 0.01), houses made of bamboo or lacking floors (AOR = 2.31, 95% CI: 1.38 to 3.89; p value 0.01), families with three or more children (AOR = 1.68, 95% CI: 1.01 to 2.79; p value 0.05) and breastmilk being the primary food after 6 months of age (AOR = 2.07, 95% CI: 1.09 to 3.93; p value 0.03). CONCLUSIONS: Ensuring access to basic hygiene services, getting water at home 24 h per day, seven days per week, using private toilets, promoting hygiene health literacy, improving house flooring, family planning and introducing a variety of foods after age 6 months could significantly prevent diarrhea among under-five children in Myanmar. This study underscores the critical role of handwashing facilities in reducing the diarrhea incidence in children.

The prevalence of vulvovaginal symptoms in Japanese women of reproductive and perimenopausal ages: A cross-sectional study across generations.

AIM: This cross-sectional study evaluated vaginal health and hygiene practices among reproductive and perimenopausal women in Japan using an online-based questionnaire. METHODS: The questionnaire included 11 well-structured questions concerning vulvovaginal symptoms and hygiene care practices. Participants' responses were anonymized and analyzed descriptively. The relationships of age, family income, occupation, and childbearing with women's concerns regarding vaginal or vulvar problems were analyzed by chi-square tests. RESULTS: About 80% of women in their 20s to 50s in Japan reported experiencing vulvovaginal symptoms. Women in their 40s had significantly fewer symptoms than women in their 20s (p = 0.04), and women in their 50s had significantly fewer symptoms than all other age groups (20s, 30s, and 40s) (p < 0.001). Among symptomatic women, 77.5% did not discuss their symptoms with anyone else and only 10% visited doctors. About 12.5% of women reported taking special care of their vagina or vulva regularly, whereas 38.2% expressed a desire to try some form of care but had not yet done so. Of the women who did not take special care of their vagina or vulva, 46.2% lacked knowledge about proper care, 42.2% did not want to spend money on care, 30.5% did not want to discuss care with others, and 21.3% were psychologically reluctant. CONCLUSION: Determination of the prevalence of vulvovaginal symptoms among Japanese women can enhance understanding of this prevalent condition and its impact on women's health. These findings may help formulate effective public health interventions and promote better hygienic practices, thus improving the well-being of women in Japan.

Unveiling disparities: a non-linear decomposition analysis of the gap in menstrual hygiene material use between adolescent women in Aspirational and the remaining districts of India.

This study aimed to investigate the factors contributing to the gap in the use of hygienic materials during menstruation to collect blood among adolescent women between Aspirational and the remaining districts of India. The study sample consisted of 114805 adolescent women (20835 women from 112 Aspirational districts and 93970 women from 595 remaining districts) from the National Family Health Survey-5. Fairlie decomposition was used to identify and measure the factors contributing to the gap in the use of hygienic materials between Aspirational and the remaining districts of India. This study determined that the use of hygienic materials during menstruation varied significantly between Aspirational and the remaining districts. While only 37% of adolescent women used hygienic materials in Aspirational districts, almost 52% did so in the remaining districts. Seventy-five per cent of Aspirational districts (84 of 112 districts) reported less than 50% use of hygienic materials, which is lower than the national average and the average of the remaining districts. It was revealed that nearly 90% of the total explained gap between the two groups was accounted for by household wealth, place of residence, exposure to mass media, and education level. Wealth was the main contributor to the gap, explaining about 46% of the difference in hygienic materials use between Aspirational and the remaining districts, followed by the place of residence (18%), exposure to mass media (15%), and education level (11%). Findings suggest that targeted interventions to improve access to hygienic materials among adolescent women in Aspirational districts, particularly those in the northern states of Uttar Pradesh, Bihar, and Chhattisgarh, are necessary. Policy efforts should focus on women from poor households, improving access to education, and expanding mass media exposure in Aspirational districts to reduce the gap in menstrual hygiene practices among adolescent women in India.

Implementation of oral hygiene practices in nursing homes - a qualitative approach among supervisor nurses.

OBJECTIVES: This study describes daily oral health care in private enhanced service housing units and nursing homes in Finland using a qualitative method. METHODS: Nineteen supervisor nurses were interviewed in the six largest cities in Finland. The interviews consisted of semi-structured questions. The interviews were then transcribed and analyzed using inductive content analysis. RESULTS: The qualitative content analysis revealed five main categories: diet, education in the oral health of older people, oral care equipment and taking care of them, caring for the mouths of residents, and professional oral health care. The results revealed that sugary snacks were given daily in the units and there was a need for oral health care education. The dental equipment of residents was taken care of well and the oral health of the residents was taken care of moderately well. Furthermore, there was a need for co-operation between dental professionals and only half of the residents had an individual oral care plan. CONCLUSIONS: It can be concluded that based on this qualitative study, the implementation of daily oral health care in most nursing homes and enhanced housing units seems to be at a sufficient level and more oral health-related practical and theoretical education is needed.

Association between early childhood caries and parental education and the link to the sustainable development goal 4: a scoping review.

BACKGROUND: The goal of the United Nations Sustainable Development Goal (SDG) 4 is to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all. The aim of this scoping review was to map the current evidence on the association between the prevalence of early childhood caries (ECC) and parental education; and to identify possible pathways by which parental education may protect against ECC. METHODS: The two questions that guided this review were: what is the existing evidence on the association between maternal and paternal education and ECC; and what are the pathways by which parental education protects against ECC? The initial search was conducted in January 2023 in PubMed, Web of Science and Scopus. Articles published in English between January 2000 and October 2022 that reported on the association between parental education and ECC were screened, and the extracted data were compiled, summarized, and synthesized. Review papers and non-primary quantitative research papers were excluded from the full-text review. Open coding was applied to develop a conceptual framework. RESULTS: In total, 49 studies were included: 42 cross-sectional, 3 case-control and 4 cohort studies. The majority (91.8%) reported on the associations between ECC and maternal (n = 33), paternal (n = 3), and parental (n = 9) level of education, and 13 (26.7%) reported on the association between parental education and the severity of ECC. Mothers with more than primary school education (n = 3), post-secondary/college/tertiary education (n = 23), and more than 4-12 years of education (n = 12) had children with lower risk for ECC. Two studies reporting on parental education found an association between maternal but not paternal education and ECC. The review suggests that achieving the SDG 4.1 may reduce the risk of ECC. Possible pathways by which maternal education protects from ECC were feeding practices, oral hygiene practices, and the use of dental services. CONCLUSION: The study findings suggests that higher maternal educational level may reduce the risk for the consumption of cariogenic diet, poor oral hygiene practices and poor use of dental services for caries prevention. However, the association between paternal education and ECC was not consistently observed, with significant associations less frequently reported compared to maternal education. Future studies are needed to define the magnitude and modifiers of the impact of maternal education on the risk for ECC.

Adolescent sleep duration: associations with social-cognitive determinants and the mediating role of sleep hygiene practices.

Insufficient sleep duration among adolescents is a widespread public health problem. Gaining better insight into social-cognitive determinants associated with adolescent sleep duration is necessary for developing effective preventive interventions to support healthy sleep. This study aimed to explore whether social-cognitive determinants regarding sufficient sleep duration were associated with sleep duration, and if these associations were mediated by collective sleep hygiene practices. Furthermore, we examined these associations for social-cognitive determinants related to not using media before bedtime and doing relaxing activities and considered whether these associations were mediated by specific sleep hygiene practices. Data were collected amongst second- and third-grade adolescents from 10 Dutch high schools. A total of 878 adolescents (mean [SD] age 13.3 [0.71] years) completed data on sleep duration, social-cognitive determinants of the Theory of Planned Behaviour (i.e., attitude, subjective norms from parents, subjective norms from peers, perceived behavioural control, intention), and sleep hygiene practices. Single- and multivariable path models were constructed and mediation by sleep hygiene practices was analysed by Monte Carlo simulation. All social-cognitive determinants except for subjective norms from peers were associated with longer sleep duration (p < 0.01). Sleep hygiene practices mediated all associations between social-cognitive determinants and sleep duration (mediation ranging from 16% to 72%). Although some of the significant associations and mediation disappeared in the multivariable model, behavioural arousal was the strongest mediator, but collective sleep hygiene practices and cognitive/emotional arousal also explained parts of the associations. The findings indicate that social-cognitive factors should not be overlooked when targeting adolescent sleep duration.

Dynamics of usage of menstrual hygiene and unhygienic methods among young women in India: a spatial analysis.

BACKGROUND: Menstruation, especially the menstrual cycle, is a vital sign for female adolescent health and maintaining menstrual hygiene is of utmost importance for menstruating girls and women. However, menstrual hygiene and management are issues that have not received adequate attention. Therefore, the present study aimed to explore spatial patterns of menstrual hygiene practices in India and to identify their socioeconomic and demographic determinants among women aged 15-24 years. METHODS: The study utilized data from the fifth round of the National Family Health Survey (NFHS-5) conducted during 2019-21 in India. The analysis was limited to 241,180 women aged 15-24 years. The statistical methods range from multinomial logistic regression, spatial autocorrelation in terms of Moran's I statistics, to spatial regression in order to understand the spatial dependence and clustering in different methods of menstrual practices across the districts of India. RESULTS: Almost half of the respondents (49.8 percent) reported using hygienic methods of bloodstain protection, while 22.7 percent still relied on unhygienic methods and 27.5 percent reported using both hygienic and unhygienic methods during their menstruation. Factors like age, place of residence, caste, religion, education, wealth index and toilet facility were found to be significantly associated with the use of unhygienic and both methods. It was also observed that the percentage of women practicing hygienic methods was predominantly higher in the Southern region. On the other hand, states like Madhya Pradesh and Bihar appeared to be hotspots for unhygienic menstrual practices. The univariate Moran's I value for unhygienic and both methods were 0.722 and 0.596, respectively, depicting high spatial autocorrelation across districts in India. In spatial regression, rural residence, illiteracy, poverty, and no toilet facility were found to be statistically significant predictors of the use of unhygienic method and both methods. CONCLUSION: Young women should be educated about the importance of menstrual hygiene practices and the physiological consequences of unhygienic practices. Furthermore, interventions should target socio-economically disadvantaged women to increase the use of sanitary napkins.

Menstrual health and hygiene among Juang women: a particularly vulnerable tribal group in Odisha, India.

BACKGROUND: Menstruation is a normal biological process that all women go through, yet it is shrouded in secrecy, taboos, and even stigma in many societies. Studies have shown that women from socially disadvantaged groups are more likely to have preventable reproductive health issues and have less understanding of hygienic menstrual practices. Therefore, this study aimed to provide an insight into the most sensitive issue of menstruation and menstrual hygiene practices among the women of the Juang tribe, recognized as one of the particularly vulnerable tribal groups (PVTG) in India. METHODS: A cross-sectional study using a mixed-method approach was carried out among Juang women in Keonjhar district of Odisha, India. Quantitative data was gathered from 360 currently married women to assess practices associated with menstruation and its management. In addition, 15 focus group discussions and 15 in-depth interviews were conducted to explore the views of Juang women on menstrual hygiene practices, cultural beliefs, menstrual problems, and treatment-seeking behaviour. Inductive content analysis was used to analyse the qualitative data, while descriptive statistics and chi-squared tests were used to analyse quantitative data. RESULTS: Most Juang women (85%) used old clothes as absorbents during menstruation. Distance from the market (36%), lack of awareness (31%), and high cost (15%) were cited as the contributing factors to the low level of sanitary napkin usage. Around 85% of women were restricted from participating in religious activities, and 94% avoided social gatherings. Seventy-one percent of the Juang women experienced menstrual problems, while only one-third of them sought treatment for their problems. CONCLUSION: Hygienic practices during menstruation are far from satisfactory among Juang women in Odisha, India. Menstrual problems are common, and the treatment sought is insufficient. There is a need for awareness generation on menstrual hygiene, the adverse effects of menstrual problems, and the provision of low-cost sanitary napkins among this disadvantaged, vulnerable tribal group.

Piagetian's principles on moral development and its influence on the oral hygiene practices of Indian children: An embedded mixed-method approach.

BACKGROUND: Moral principles in children can influence their oral hygiene practices and can be beneficial in providing better oral health care. AIM: To assess the consistency of Piaget's moral development principles in Indian children aged 7 to 11 years and evaluate its influence on their oral hygiene practices. DESIGN: The first phase of the embedded mixed-method approach included telephone interviews of 50 children on eight situations of moral development as suggested by Jean Piaget. Children were categorised into heteronomous and autonomous moralities based on the content analysis. The second phase of the study included a semi-structured qualitative interview on knowledge and practice behaviour of children on oral hygiene maintenance. RESULTS: There was no significant difference in the overall moral development of children aged 7 to 9 years and 9 to 11 years (p = .57). Only 4.8% of girls had heteronomous morality, and a significant difference was noted between boys and girls (p = .014). There was a significant difference in the oral hygiene practices observed between heteronomous morality and autonomous morality children. CONCLUSION: Children were autonomous in their morality at 7 to 9 years of age. Children with autonomous morality performed better oral hygiene practices than children with heteronomous morality.

Oral health status and hygiene practices among visually impaired adolescents from a school in Kenya.

BACKGROUND: Visual impairment affects a significant population globally. The aim of this study was to determine the oral health status and oral hygiene practices among visually impaired adolescents from a school in Kenya. METHODS: A descriptive cross-sectional study was carried out among 159 adolescents aged 10-19 years attending the largest public primary boarding school for the blind in Kenya. A questionnaire was used to record participants' socio-demographic variables and oral hygiene practices. Clinical examination was undertaken to assess oral health status which consisted of oral hygiene, gingival health, and dental caries. Bivariate analyses were conducted to compare dental health outcomes across socio-demographic characteristics. RESULTS: There were 69 (43.4%) and 90 (56.6%) participants in Category I and II visual impairment respectively, 85 (53.5%) were male and 74 (46.5%) were female. Study participants were divided into three age categories: 10-12 years 48 (30.2%), 13-15 years 67 (42.1%), and 16- 19 years 44 (27.7%), with an overall mean age of 13.9 ± 2.3. All participants brushed their teeth, majority 107 (67.3%) brushed two or more times daily. Only 66 (41.5%) of the participants replaced their toothbrushes at 3 months. Sex (p =< 0.001) and age (p = 0.04) influenced frequency of toothbrush replacement. The average plaque score and gingival score index was 0.95 ± 0.45 and 0.28 ± 0.25 respectively, with gingivitis prevalence of 88.1%. Overall dental caries prevalence was 44.7%, [42.1%)] permanent dentition and [8.2%] deciduous dentition. Mean DMFT and dmft were 0.44 ± 0.60 and 0.12 ± 0.32 respectively. DMFT had a statistically significant association with sex (t = 1.82, p = 0.03). Oral hygiene practices did not influence oral hygiene and dental caries status. However, a statistically significant association was reported between frequency of toothbrush replacement and gingival score index ("p" =< 0.001). CONCLUSIONS: The study reported general good oral hygiene, prevalent gingivitis 140 (88.1%), and almost half of the study population affected by dental caries 71 (44.7%). Most participants were unaware of using fluoridated toothpaste and of needing to change toothbrushes within 3 months. Frequency of toothbrush replacement was reported to influence gingival score index.

Assessment of Young Mothers' Oral Hygiene Practices during Pregnancy and Their Knowledge of Children's Oral Health in Northern Greece.

AIM: The aim of the study was to assess maternal knowledge about oral health practices for children along with oral hygiene perceptions of mothers during pregnancy in the city of Thessaloniki, Greece. MATERIALS AND METHODS: This cross-sectional study was conducted among 300 newly delivered mothers who were admitted to the obstetrician/gynecological (OB/GYN) University Clinic in Thessaloniki, Greece, to give birth. A three-part, self-reported, 40-item questionnaire was designed, collecting socioeconomic data, perceptions, and practices regarding maternal oral hygiene during pregnancy and their knowledge in relation to children's oral health. Collected data were recorded, tabulated, and statistically analyzed with SPSS (Version 24.0), and p < 0.05 was accepted as statistically significant. RESULTS: The sample consisted of mainly Greek, married, university alumni mothers less than 35 years of age. Self-reports of oral hygiene practices during gestation were sufficient but an inadequate level of regular dental visits was recorded. Poor knowledge was equally noted, regarding children's oral health, in the domains of fluoride toothpaste usage, the age of the first dental visit, supervised toothbrushing, nighttime breastfeeding, potential hazards of pacifier use, and thumb sucking. All factors were significantly associated with the mothers' education level (p < 0.05). CONCLUSION: Newly-delivered mothers presented with a lack of knowledge regarding mother/caregiver-related risk factors associated with early childhood caries (ECC), the timing of establishing a dental home, and misconceptions about the safety of dental visits during pregnancy. CLINICAL SIGNIFICANCE: Healthcare professionals interacting with pregnant women or young mothers are a vital element to bridge the existing gap in knowledge and assist those socially and educationally deprived.

How has public perception of food safety and health risks changed a year after the pandemic and vaccines roll out?

The recent coronavirus pandemic (COVID-19) has caused unprecedented turmoil and spurred fears that have profoundly changed the public's social and health behaviours, including the perception of food safety risks. One year after the pandemic and the global vaccination campaign, the public perception of food safety and the changes in their hygiene behaviour, health risks concerns, and trust were studied in Jordan, Lebanon, and Tunisia using a cross-sectional online survey. The results of 538 subjects showed a rise in the frequency of hygiene practices, notably in handwashing. Sixty-four percent of the participants were vaccinated, a proportion made up mainly of the Jordanians and Lebanese. For 66% and 64% of the two population groups, respectively, there were no longer trust concerns about COVID-19 health risks following vaccination, whereas the worries about getting COVID-19 persisted for others. Only 47% of participants trusted eating food prepared by vaccinated food handlers. A great majority of the Tunisians (81%) showed varying degrees of concern about COVID-19 transmission from food and the lowest vaccination rate (33%). The current study demonstrated that the impact of vaccination policy positively affects public perception of food-related risks during the pandemic. On the other hand, 33% of the surveyed Jordanians and Tunisians lost trust in the health authorities' management of the pandemic, and 45% of the Lebanese still don't trust them. Communication strategies on health and food safety with the public still represent a challenge for these and probably other countries in the Middle East and North Africa (MENA). Strategies for building and maintaining public trust are crucial to curb persistent fear of food, hence, avoiding potential stigmatization affecting the food economy by promoting health awareness and positive changes in food safety perceptions for safer practices.

Evaluation of potentiality of traditional hygienic practices for the mitigation of the 2019-2020 Corona Pandemic.

The coronavirus outbreak threatens global well-being, costing thousands of lives and an unstable economy. Traditional hand-washing (HaWa) with clean water and hand-washing sanitizers (HaWaSas) are among WHO recommended practices against the outbreaks. HaWaSa and HaWa lacked proper quality monitoring evaluation that may pose health risks. The current study investigates the potential of traditional hygienic practices adopted to mitigate the 2019-2020 Pandemic. It involved assessing the effectiveness of 15 HaWaSa collected from the Dodoma market. Thirty volunteered participants were subjected to different hygienic practices involving HaWa and HaWaSa. The obtained hand-swabbed samples were subjected to the streak plate technique for inoculation, followed by counting colonies. The results revealed that, among the collected HaWaSa brands, only 33.3% were certified by the Tanzania Bureau of Standards (TBS). In the setting under no hand-wash, each client had a different number of colony counts. HaWa did not eliminate all colonies since water acted as a secondary source while only one sanitizer proved effective. The p-values obtained in either setting were greater than 0.05, indicating that each variable was independent. Despite global awareness and fighting against the Coronavirus Disease 2019 (Covid-19) outbreak, quality monitoring of all diagnostic tools, preventive HaWaSa, and related drugs should be prioritized for human safeguard.

Risk factors for food poisoning among self-catering university students.

Limited research has investigated self-catering university students' food hygiene practices that may increase their vulnerability to food poisoning. This study assessed the practice-related risk factors for food poisoning among 600 self-catering university students. A validated questionnaire was self-administered to collect data about their food hygiene practices in the previous 12 months. Factors associated with the prevalence of food poisoning were determined using logistic regression methods. Analyses showed significant associations of the use of wooden chopping boards and the consumption of unwashed fruits, with the prevalence of food poisoning (p < 0.05). However, the strongest association was for thawing of meat at room temperature (odds ratio for thawing at room temperature versus inside refrigerator, 6.07, 95% CI 3.98-9.25). Findings highlight the need for risk-based food hygiene training to inculcate safe food handling practices among self-catering university students.

U.S. active-duty service women's urogenital health and operational readiness through the lens of the IBM-WASH model: A systematic integrative review.

AIM: Identify literature regarding urogenital health and hygiene practices/behaviors of U.S. active-duty service women (ADSW) with attention to environmental conditions; access to water, sanitation, and hygiene (WASH) resources in austere environments. Synthesize relationships among the 3-dimensions and 5-levels of the Integrated Behavioral Model for Water, Sanitation, and Hygiene (IBM-WASH). BACKGROUND: ADSW face sex-specific urogenital health challenges due to decreased access to WASH resources in austere environments, leading to increased risk for urogenital infection-related outcomes (urinary tract infections, vulvovaginal candidiasis, and bacterial vaginosis). During military conflicts in Afghanistan and Iraq, urogenital infections in ADSW were reported as one of the top five medical encounters, and one of the top seven reasons for medical evacuation. METHODS: A systematic review was performed in MEDLINE, CINAHL, Embase, and ClinicalTrials.gov databases, between January 2007-November 2021, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses as a reporting guideline. Eligible literature was evaluated utilizing the Johns Hopkins Research Evidence Appraisal Tool. WASH interactions were mapped using the IBM-WASH interactive matrix. RESULTS: Evidence gaps include shifting focus from "deployment" to environmental austerity; lack of training/education; shifting male-centric culture; and innovative technologies for safety/security. CONCLUSIONS: The IBM-WASH framework allowed for quantification and interpretation of complex interactions occurring in real world austere environments. Some could be overcome individually, but in aggregate they lead to progressive urogenital conditions and potential mission failure. Prevention, diagnosis, and treatment can mitigate disease sequelae. Preventive knowledge and access to innovative technologies designed for ease and private use are critical to preserve operational readiness.

Oral hygiene practices and their sociodemographic correlates among adults in Burkina Faso: results from the First National Survey.

BACKGROUND: Sociodemographic parameters are the driving determinants of oral hygiene practices. This study aims to describe oral hygiene practices and associated sociodemographic factors in the Burkinabè population using the first nationally representative data. METHODS: This descriptive, cross-sectional study included 4677 adults through multistage cluster sampling performed during the first WHO STEPS survey conducted in 2013 in Burkina Faso. The practices we considered were the frequencies of tooth cleaning, fluoridated toothpaste use and dentist visits within the last six months. Sociodemographic variables and oral hygiene practices were described, and the first variables were used as the explanatory variables for the seconds in the multivariable analyses. RESULTS: Individuals who cleaned teeth at least once a day represented 82.8% and at least twice a day represented 31.4%; 25.6% used fluoridated toothpaste and 2.1% visited a dentist. With the highest odds ratio, only being educated was a favourable factor for each oral hygiene practice. Living in an urban area or being a younger adult were favourable factors for cleaning teeth at least twice a day or the use of a fluoridated paste. Female gender applied more to regular tooth cleaning, as well as to dentist visits. CONCLUSION: Cleaning teeth at least once a day was common among Burkinabè, while cleaning at least twice a day, the use of fluoridated paste or dentist visits were infrequent. Education was the key favourable determinant for healthy oral hygiene practices, and improving oral health literacy interventions through basic health education should be promoted.

Peroxyacetic acid and chlorine dioxide unlike chlorine induce viable but non-culturable (VBNC) stage of Listeria monocytogenes and Escherichia coli O157:H7 in wash water.

The elaboration of guidelines for the industry to establish minimum concentration to prevent cross-contamination during washing practices based on operational limits is the core of the recommended criteria for the use of sanitizers. Several studies have evidenced that sanitizers reduced the levels of foodborne pathogens. However, they might lead to the progress into a viable but non-culturable (VBNC) state of the cells. This evidence has raised concerns regarding the effectiveness of the recommended washing practices for the inactivation of microbial cells present in the process wash water (PWW). The present study evaluated if the most commonly used sanitizers, including sodium hypochlorite (chlorine), peroxyacetic acid (PAA) and chlorine dioxide (ClO2) at established operational limits induced the VBNC stage of Listeria monocytogenes and Escherichia coli O157:H7. Prevention of cross-contamination was examined in four different types of PWW from washing shredded lettuce and cabbage, diced onions, and baby spinach under simulated commercial conditions of high organic matter and 1 min contact time. The results obtained for chlorine showed that recommended operational limits (20-25 mg/L free chlorine) were effective in inactivating L. monocytogenes and E. coli O157:H7 in the different PWWs. However, the operational limits established for PAA (80 mg/L) and ClO2 (3 mg/L) reduced the levels of culturable pathogenic bacteria but induced the VBNC state of the remaining cells. Consequently, the operational limits for chlorine are satisfactory to inactivate foodborne pathogens present in PWW and prevent cross-contamination but higher concentrations or longer contact times should be needed for PAA and ClO2 to reduce the likelihood of the induction of VBNC bacteria cells, as it represents a hazard.

Effect of food safety training on behavior change of food handlers: A case of orange-fleshed sweetpotato purée processing in Kenya.

Sweetpotato purée processing is new to Kenya and a rapidly growing value addition activity among informal, small, and medium-sized food enterprises (SMEs) in sub-Saharan Africa (SSA). Inadequate knowledge of food safety and poor hygiene practices by food handlers, low level of compliance with Good Manufacturing Practices (GMPs), and microbial contamination are major food safety challenges in orange-fleshed sweetpotato (OFSP) purée processing in Kenya. The extent of food safety training in enhancing food safety in rural-based SMEs and food processing environments has not been fully investigated. This study aimed at evaluating the impact of food safety training on food safety knowledge and hygiene practices of food handlers and in control of microbial contamination in OFSP purée processing in Kenya. Pre- and post-food safety training assessments were conducted to determine food handler's (N = 14) knowledge and practices on food safety. Food, water, and swab samples (n = 62) from the processing environment were collected before and two months after the training and analyzed for food hygiene indicator microorganisms. The findings indicate a significant (p < 0.05) improvement in overall food safety knowledge and practices of food handlers after the training. Poor knowledge scores were exhibited on aspects of cross-contamination, cleaning, and sanitation but these significantly (p < 0.05) improved after the training. Similarly, microbial counts on food equipment surfaces, installations, personnel hands, and in the final product (OFSP purée) significantly (p < 0.05) declined to acceptable levels after the food safety training. Total counts, yeasts and molds, S. aureus, Enterobacteriaceae, and total coliforms counts in the packaged OFSP purée were 2.6, 1.8, 1.5, 1.9, and 1.2 LOG CFU/g respectively hence suitable for its current application as an ingredient in baked products. The findings from this study indicate food safety training as an appropriate tool for improving food handler's knowledge and hygiene practices as well as enhancing microbial safety and quality of processed foods in SMEs if necessary food safety support resources are provided.
