Effectiveness of physical exercise for people with chronic diseases: the EFIKRONIK study protocol for a hybrid, clinical and implementation randomized trial.

BACKGROUND: Chronic illnesses are the leading cause of morbidity and mortality and threaten the sustainability of healthcare systems worldwide. There is limited evidence in terms of the best modality and intensity of physical activity for improving cardiorespiratory capacity and quality of life in patients with chronic conditions. The objective of the EfiKroniK study is to estimate the common effect of innovative, individualized and supervised physical exercise, on cardiorespiratory functional capacity and quality of life across people with different chronic conditions. METHODS/DESIGN: This is a multicentre clinical trial with a type I hybrid effectiveness-implementation design, including 370 patients each with one of four different chronic illnesses: solid cancer, blood cancer, chronic obstructive pulmonary disease or schizophrenia. Patients will be randomly divided into two parallel groups, stratified by illness type. Patients in both groups will receive a standard healthy life prescription (PVS, from the Spanish "Prescribe Vida Saludable") and additionally, the EfiKroniK group will be prescribed a physical exercise programme tailored to each patient in terms of intensity in each session. The primary outcome variables will be cardiorespiratory functional capacity and quality of life. The secondary outcome variables will be signs and symptoms, psychological and social factors and specific laboratory parameters. We will also analyse the dose-response effect of the physical exercise programme. Qualitative variables will describe patients' perception of the utility and suitability of the EfiKroniK programme, as well as their expectations and satisfaction, identifying barriers to and facilitators of the EfiKroniK implementation process through discussion groups. The study will be carried out on an intention-to-treat basis, comparing changes throughout the 1-year follow-up between groups, adjusting for baseline, by performing mixed-effect analysis of covariance. We will estimate the effect of time on repeated measures in each subject and changes in the EfiKroniK and PVS groups over time. DISCUSSION: The study will provide the data necessary to allow us to prescribe physical exercise in a similar way to a drug and as a key part of the treatment of chronic illnesses within our healthcare system.

An Exploration of Service Providers' Experiences With Latinos Convicted of a Sex Offense.

Despite the growing Latino presence in the U.S. criminal justice system and among those who have committed sex offenses specifically, little is known about the barriers and challenges faced by this population when accessing treatment services. This study sought to gather more information about responsivity factors that may be specific to Latinos who have committed sexual offenses. Service providers who worked with Latinos convicted of sexual offenses completed an online survey and answered questions regarding perceived challenges and barriers they encountered when working with Latino clients and were asked to provide recommendations concerning services and treatment provision. Service providers frequently reported issues related to a lack of culturally sensitive services, bilingual professionals, and clients' limited knowledge about the U.S. legal system. Among service providers with experience working with undocumented Latino immigrants, some indicated specific challenges such as stressors related to their immigration status and a lack of resources. Professionals' recommendations were consistent with the challenges reported and findings are discussed as they pertain to responsivity issues in the provision of treatment services to Latino individuals who have committed sexual offenses.

Contributing Risk Factors for Substance Use Among Youth in Postconflict Liberia.

Substance use is prevalent among youth in postconflict African countries and is associated with a number of public health problems such as poverty, child homelessness, and school truancy. This qualitative study explores the risk factors associated with substance use among Liberian youth from the perspective of public-school students. Nine focus groups were conducted with 72 Liberian public-school students (35 female, 37 male). Multiple risk factors for substance use among Liberian youth were identified through qualitative analysis, including emotional instability, gender, fear of academic failure, accessibility to substances within the school and community, poverty, and unintentional drug use. These findings are important to public health campaigns and postconflict recovery in Liberia, and may also inform prevention programs for substance use among Liberian youth.

Are Latinos Who Commit Sexual Offenses Different? A Closer Examination of Characteristics and Offense Patterns.

Research examining ethnic and cultural differences among individuals who commit sex offenses remains limited. Specifically, literature focusing on sex offenses committed by Latinos is scarce. Using archival data from a large sample of individuals who committed sex offenses, this study explored differences between Latino, White, and African American individuals related to their characteristics, the offenses, and the victims. Latinos in the sample were more likely to have a lower educational level, and to be living with the victim, than either their White or African American counterparts. To further understand the influence of cultural background, the study also examined differences within the Latino group based on their country of origin. Within the Latino sample, differences emerged in their educational level, criminal background, and psychiatric history. These findings are discussed as they pertain to future research and current practices related to the management and treatment of Latinos who commit sexual offenses.

A sequential logit model of caretakers' decision to vaccinate children for the human papillomavirus virus in the general population.

OBJECTIVES: This study explores the predisposing, enabling, and need-based factors associated with parents' or guardians' decision to have their child initiate, continue, and complete the human papillomavirus (HPV) vaccine. METHODS: Parents and guardians of children between the ages of 9 and 17years who completed the 2010 Behavioral Risk Factor Surveillance System survey collected by the Center for Disease Control (CDC, 2010) were analyzed. Utilizing Andersen's health care beliefs model, we explored the sequential nature of the decision to vaccinate (i.e., the decision to receive the first, second, and third dose), thereby allowing the independent variables to vary across each transition. RESULTS: Among all children, 3.7% received exactly 1 shot, 16.3% received at least one shot, and 8.9% received all three shots. Among those who received at least one shot, 22.4% received exactly one shot, 23.7% received exactly 2 shots, and 54.9% completed all 3 shots. A differential impact was observed across transitions. Predisposing factors, such as being Hispanic (OR=1.9) and child age (OR=1.4), significantly predicted the decision to receive the first dose but enabling factors, such as having a regular physician (OR=4.5) and income (OR=.74) were more important for predicting completion. CONCLUSIONS: The decision to initiate and complete HPV vaccination depends on a specific mix of enabling, predisposing, and need-based factors. Our analysis underscores the importance of modeling the vaccination decision in a manner that is consistent with how primary caregivers navigate real-life health care decisions for their children.

Lead exposure from honey: meta-analysis and risk assessment for the Arab region.

The Codex Alimentarius Commission has adopted a maximum level for lead in honey (0.1 mg/kg). Despite representing a population of more than half a billion, exposure and risk assessments for lead specific to the Arab region are lacking. The aim of this work was to collect analytical data for lead in honey available in Arab countries and to assess the risk caused by exposure to lead from these samples for local consumers. A regional mean lead concentration in honey, obtained through a meta-analysis of 57 studies, was used in deterministic risk assessments for adults (nephrotoxicity and cardiovascular effects) and young children (developmental neurotoxicity). A regional pooled mean concentration of 0.12 mg/kg [95%CI: 0.07-0.21] (0.13 mg/kg, if non-detects are considered at their highest possible value) was obtained. Margins of exposure of 363 [71-17182] and 865 [168-40909] were calculated for adults, and of 48 [9-2273] for children, indicating potential concern for the latter population subset. These values were produced using GEMS consumption data, and considering the same intake for both children and adults, potentially overestimating the risk for children. Nevertheless, food competent authorities should consider measures to reduce lead concentration in honey available for sale in the region to prevent trade constraints and to better protect vulnerable populations.

Simulated use of thresholds for precautionary allergen labeling: Impact on prevalence and risk.

Heterogeneity and overuse of precautionary allergen labelling (PAL) in prepackaged foods have eroded its risk communication efficacy. Experts recommend applying PAL based on allergen concentration thresholds, but adoption remains limited. The aim of this study was to quantitatively assess the potential impact of this approach using Monte Carlo risk simulations. Four allergens and 9 food categories were considered in 2 scenarios: (1) consumption of products currently carrying PAL in Canada where individuals with food allergy (FA) are assumed to consume them, and (2) consumption of products without PAL, in a hypothetical context where PAL is applied based on thresholds that would protect 99 % (ED01) and 95 % (ED05) of individuals with FA, and individuals with FA systematically avoid products with PAL. In scenario (1), although several cases studied would cause <10 reactions/10 000 eating occasions (e.o.), there were also many that would cause >20 reactions/10 000 e.o. Cross-contact milk posed the highest risk (max. 1120 reactions/10 000 e.o.), and peanut, the least (max. 10 reactions/10 000 e.o.). In scenario (2), consumption of products without PAL, when using thresholds for PAL based on ED01, could lead to a maximum of 15 reactions/10 000 e. o. for all studied cases, and based on ED05, to 57 (if excluding dark chocolate with milk PAL). In most cases, the estimated number of reactions per 10 000 e.o. attributed to products with PAL currently on the market would be higher (p < 0.05) than that attributed to products without PAL, if PAL is applied based on the simulated thresholds. Thus, a threshold driven approach to adopt PAL on prepackaged foods, while advising consumers to avoid these products, could be beneficial for individuals with FA in Canada, as products without PAL would result in very few and generally mild adverse reactions.

Stochastic Health Risk Assessment of Aflatoxin M1 in Cow's Milk among Lebanese Population.

This study quantitatively assessed AFM1 exposure through consumption of cows' milk in Lebanese adolescents and adults. Lebanon-specific, non-aggregated data on (i) milk intake and body weight - from an existing survey for adults and from a new survey for adolescents, and (ii) AFM1 occurrence in milk, were fitted to distributions and incorporated into a probabilistic model. Risk of hepatocellular carcinoma (HCC) for milk consumers was estimated considering the incidence of hepatitis B virus in Lebanon and characterized using the margin of exposure (MOE). All subgroups' mean risk estimates, expressed as additional HCC cases per 100000 population per year, were significantly different (p<0.05), and ranged from 2.2x10-4 for adult males to 4.9x10-4 for adolescent males. This variation is attributed to significant differences in body weight and milk intake. MOE identified adolescent males and females as at-risk populations (mean 9628 and 8108, respectively). For adults, levels of concern were only reached with extreme consumption and/or contamination events. Considering that exposure from other sources (e.g., dairy) is cumulative, control of AFM1 in milk in Lebanon should be a risk management priority to ensure protection of younger populations.

Animal Food Products to Support Human Nutrition and to Boost Human Health: The Potential of Feedstuffs Resources and Their Metabolites as Health-Promoters.

Recent attention has been given to animal feeding and its impact on human nutrition. Animal feeding is essential for meeting human dietary needs, making it a subject of significant interest and investigation. This review seeks to outline the current understanding of this disciplinary area, with a focus on key research areas and their potential implications. The initial part of the paper discusses the importance of animal feed resources and recognizes their crucial role in guaranteeing sufficient nutrition for both humans and animals. Furthermore, we analyzed the categorization of animal feeds based on the guidelines established by the National Research Council. This approach offers a valuable structure for comprehending and classifying diverse types of animal feed. Through an examination of this classification, we gain an understanding of the composition and nutritional content of various feedstuffs. We discuss the major categories of metabolites found in animal feed and their impact on animal nutrition, as well as their potential health advantages for humans. Flavonoids, polyphenols, tannins, terpenoids, vitamins, antioxidants, alkaloids, and essential oils are the primary focus of the examination. Moreover, we analyzed their possible transference into animal products, and later we observed their occurrence in foods from animal sources. Finally, we discuss their potential to promote human health. This review offers an understanding of the connections among the major metabolites found in feedstuffs, their occurrence in animal products, and their possible impact on the health of both animals and humans.

"Vegan" and "plant-based" claims: risk implications for milk- and egg-allergic consumers in Canada.

The market share of foods carrying labels suggesting absence of animal ingredients has significantly increased in recent years. The purpose of this study was to document the purchasing behaviour of egg- or milk-allergic consumers vis-à-vis food marketed as "vegan" and "plant-based", and to evaluate the associated allergenic risk. A survey was conducted among egg- and milk-allergic consumers and revealed that 86% (margin of error 5.4%; confidence level 95%) would buy "vegan" products, indicating this label may be perceived as a substitute for "free from milk and eggs". To assess the risk posed by these products, 87 prepackaged foods with "vegan" and/or "plant-based" claims purchased in Quebec were tested for milk proteins, and 64 for egg proteins. Overall, 5.7% and 0% occurrence of milk and egg proteins, respectively, were observed, suggesting that the analysed prepackaged foods carrying "vegan" and/or "plant-based" labels pose little risk to egg- or milk-allergic consumers. However, this is likely due to allergen management practices applied by the Canadian manufacturers of the products tested, and should not be attributed to the use of "vegan" or similar labels. Enhanced regulatory requirements for the use of these labels, and an education campaign on their meaning with respect to allergy-related risks, are necessary to better inform and protect egg- and milk-allergic consumers.

Risk assessment supporting the establishment of a maximum residue limit for ractopamine in beef liver, applicable in the Arab Republic of Egypt.

In 2012, the Codex Alimentarius Commission adopted maximum residue limits (MRLs) for ractopamine in pig and cattle tissues. Egypt, a country that records a high consumption of beef liver, conducted a health risk assessment to estimate the risks associated with the adoption of Codex MRLs and the possible adoption of alternative values that may offer higher protection. Ractopamine was characterized based on previous assessments performed by international regulatory agencies, and an acceptable daily intake was set at 1 µg/kg bw for both chronic and acute ractopamine exposure. Beef liver consumption data for the Egyptian population were collected through a field survey (529 households, 1929 individuals). The standard body weight of 60 kg was used, as well as 70 kg, as a potentially more representative weight for the Egyptian population. Simulations showed that when the MRL for ractopamine in beef liver is set to 40 µg/kg (Codex MRL) or 20 µg/kg, the health-based guidance value of 1 µg/kg bw was not exceeded, as a result of chronic or acute exposure. An MRL of 20 µg/kg of ractopamine in beef liver was shown to provide optimum protection of Egyptian consumers, considering other potential sources of ractopamine intake and abnormally high consumption patterns, and was therefore recommended for adoption in Egypt. This study presents the inputs, model, and results of the probabilistic risk assessment that supported such recommendation. PRACTICAL APPLICATION: Residues of veterinary drugs, such as ractopamine, accumulate in animal tissues and may pose a risk to consumers. Establishing maximum residue limits (MRLs) will help importers by giving them the necessary visibility for commercial trade. It will also benefit Egyptian consumers, large consumers of beef liver, who will be better protected with a lower MRL than the internationally recommended one.

[Emotional overload of health personnel of the Navarra Health Service during the SARS-CoV-2 pandemic]. / Sobrecarga emocional del personal sanitario del Servicio Navarro de Salud durante la pandemia del SARS-CoV-2.

INTRODUCTION: Health care workers faced unprecedented levels of emotional burden related to the COVID-19 pandemic.. This study aims to find out the self-perception of the state of emotional overload of the professionals of the Navarre Osasunbidea Health Service (SNS-O) at two moments during the pandemic and its associated factors. METHOD: Cross-sectional study using a questionnaire that includes the Emotional Overload Self-Assessment Scale sent by email to all SNS-O health professionals at two moments of the pandemic, in October 2020 and October 2021. Results of the global scale and of the subscales '"fear-anxiety"' and ""affective response"' were compared between the two moments of measurement according to position, field, area and service using ANCOVA models. RESULTS: The number of responding participants in the 2020 survey was 1 485 (11,3%) and 950 in the 2021 survey (7,3%). The mean difference for overall score between 2020 and 2021 was -1.87 (95% CI: -2.38, -1.35), indicating less worrying results with the passage of time since the start of the pandemic, with some differences accross occupational categories. CONCLUSIONS: The year 2020 had a great impact on the emotional overload that decreased the following year. One of the greatest fears of health personnel during their occupational exposure to epidemic infectious diseases continues to be the fear of contracting the disease and transmitting it to their family members and social environment. As the proximity to the patient and their environment increases, the probability of psycho-emotional affectation increases.

OBJETIVO: Los trabajadores de la salud se enfrentaron a niveles sin precedentes de carga emocional relacionada con la pandemia de la COVID-19. Este estudio pretende conocer la autopercepción del estado de sobrecarga emocional de los profesionales del Servicio Navarro de Salud-Osasunbidea (SNS-O) en dos momentos durante la pandemia y sus factores asociados. Método: Estudio transversal mediante el uso de un cuestionario que incluye la Escala de Autoevaluación de Sobrecarga Emocional, enviado por correo electrónico a todos los profesionales sanitarios del SNS-O en dos momentos de la pandemia, en octubre de 2020 y octubre de 2021. Los resultados de la escala global y de las subescalas '"miedos-ansiedad"' y '"respuesta afectiva"' se compararon entre los dos momentos de medición según puesto de trabajo, ámbito, área y servicio, mediante modelos ANCOVA?.  Resultados: Participaron en la encuesta de 2020 1.485 (11,3%) sanitarios y 950 (7,3%) en la encuesta de 2021 de. La diferencia media para el score global entre 2020 y 2021 fue -1.87 (95% IC: -2.38, -1.35), indicando una reducción de la sobrecarga emocional con la evolución de la pandemia, con algunas diferencias entre categorías profesionales. CONCLUSIONES: El año 2020 tuvo gran impacto en la sobrecarga emocional que disminuyó al año siguiente. Uno de los mayores temores del personal sanitario durante su exposición laboral a enfermedades infecciosas epidémicas sigue siendo el miedo a contraer la enfermedad y transmitirla a sus familiares y entorno social. Conforme aumenta la proximidad con el paciente y su entorno, incrementa la probabilidad de afectación psicoemocional.

Differential effects of high dose omega-3 fatty acids on metabolism and inflammation in patients with obesity: eicosapentaenoic and docosahexaenoic acid supplementation.

Background: Obesity is complicated by low-grade chronic inflammation characterised by increases in inflammatory proteins and cells in peripheral blood. It has been known that omega-3 fatty acids (FA) like eicosapentaenoic (EPA) and docosahexaenoic (DHA) could modulate the inflammatory process and improve metabolic markers. Objective: This study aimed to determine the effect of high-dose omega-3 FA on metabolic and inflammatory markers among patients with obesity and healthy volunteers. Methods: This prospective study included 12 women with obesity (body mass index [BMI] ≥ 35.0 kg/m2) and 12 healthy women (BMI < 24.0 kg/m2) who were supplemented with a dose of 4.8 g/day (3.2 g EPA plus 1.6 g DHA) for 3 months followed by no treatment for 1 month. Plasma metabolic and inflammatory markers and levels of mRNA transcripts of CD4+ T lymphocyte subsets were determined monthly. Results: None of the participants exhibited changes in weight or body composition after study completion. EPA and DHA supplementation improved metabolic (insulin, Homeostatic Model Assessment of Insulin Resistance [HOMA-IR], triglyceride [TG]/ high-density lipoprotein [HDL] ratio, TG, and arachidonic acid [AA]/EPA ratio) and tumor necrosis factor-alpha (TNF-α). Moreover, the levels of mRNA transcripts of T CD4+ lymphocyte subsets (TBX21, IFNG, GATA-3, interleukin [IL]-4, FOXP3, IL-10 IL-6, and TNF-α), were down-regulated during the intervention phase. After 1 month without supplementation, only insulin, HOMA-IR and the mRNA transcripts remained low, whereas all other markers returned to their levels before supplementation. Conclusion: Supplementation with high-dose omega-3 FAs could modulate metabolism and inflammation in patients with obesity without weight loss or changes in body composition. However, these modulatory effects were ephemeral and with clear differential effects: short-duration on metabolism and long-lasting on inflammation.

Experimental effects of chocolate deprivation on cravings, mood, and consumption in high and low chocolate-cravers.

This study examined how deprivation of chocolate affects state-level chocolate cravings, mood, and chocolate consumption in high and low trait-level chocolate-cravers. After identifying high and low chocolate cravers (N=58), half of the participants were instructed not to eat any chocolate for 2weeks. This created four experimental groups: deprived high-cravers (n=14), deprived low-cravers (n=14), non-deprived high-cravers (n=15), and non-deprived low-cravers (n=15). Following 2-week deprivation, state-level food cravings, mood, and chocolate intake were measured in a laboratory setting and compared across groups. Analyses revealed that anxiety increased over time for high-cravers (both deprived and non-deprived); state-level chocolate- and food-craving increased over time for both deprived groups and non-deprived high-cravers; non-deprived high-cravers ate the most chocolate; and, high-cravers were more joyful and guilty than low-cravers after eating chocolate in the laboratory. Theoretically, these results suggest that chocolate consumption may be better explained by trait-level of chocolate craving than by deprivation and highlighted significant differences in mood, state-level cravings, and chocolate intake between cravers and non-cravers following deprivation.

Impact of fasting on food craving, mood and consumption in bulimia nervosa and healthy women participants.

Researchers have found that dietary restraint increases food cravings and may contribute to loss of control over eating. Negative mood states often precede food cravings and binge eating. In the present study, we tested the influence of a prolonged food deprivation period over emotional states and food cravings. Twenty-one bulimia nervosa participants and 20 healthy women participants were asked to refrain from any eating for 20 hours and reported, at baseline, after 6 hours and at the end of the fasting period, their mood and craving states. Food consumption was also measured. Fasting increased food cravings in both groups but increased negative mood in healthy women only. Bulimia nervosa participants reported improved mood following food deprivation. Whereas Bulimia nervosa and healthy women participants ate moderate and similar amounts of food following the 20-hour fasting period, food cravings were significantly associated with the number of calories ingested. These findings are congruent with self-regulation theories that predict that prolonged fasting may reduce negative emotions in women with bulimia nervosa.

Characterizing Elder Abuse in the UK: A Description of Cases Reported to a National Helpline.

The abuse of older adults by someone in a position of trust-also known as elder abuse (EA)-has a severe impact on victims and society. However, knowledge about EA in the UK is limited in comparison to other types of interpersonal violence and international knowledge. The present study utilized secondary data from a UK national EA helpline to investigate the characteristics of reported cases. Over a one-year period between 2017 and 2018, 1,623 records met inclusion criteria. Descriptive statistics are provided to describe this sample. Most cases reported to the helpline pertained to female victims, suffering from financial or psychological abuse. Co-occurrence of different abuse types was common. Findings provide updated knowledge about the phenomenology of EA cases in the UK. Recommendations are provided for advancing research in this area, including the need for examining cases across longer periods of time with a view to informing practice and policy.

Allergen management under a voluntary PAL regulatory framework - A survey of Canadian food processors.

Canadian regulations require food business operators (FBOs) to implement preventive controls to manage allergens and ensure their accurate declaration. However, the use of precautionary allergen labelling (PAL) is voluntary and competent authorities provide limited guidance on its use. The objective of this study was to present an overview of Canadian FBOs' current allergen management practices, including the mechanisms used to evaluate the need for PAL in finished products, and to investigate potential areas for improvement. Canadian FBOs were invited to answer an online survey of 48 questions covering allergen management practices and perceptions. Eighty-four full survey responses (margin of error of 9% at a 90% confidence level) were obtained. Differences in responses to multiple choice questions per company size were determined using chi-square and Fisher's exact tests. Kruskal-Wallis tests were used to analyse responses to rating or forced ranking questions. Survey respondents' allergen management practices were based on a combination of recognized best practices, third-party quality systems' standards, and regulatory requirements. Concerning practices related to the criteria used to reach PAL decisions were noted, which could be addressed with increased awareness and use of risk-based approaches and a clearer regulatory policy. Analytical testing applicability and interpretation, access to information on unintentional allergen presence in raw materials, and clarity on the expectations related to the current regulatory framework on food allergens and its enforcement, were identified as challenges faced by Canadian FBOs. The results of this survey and its analysis could be used by regulators - to inform potential policy changes, by FBOs - to map industry practices, and by allergic consumers - to better understand how manufacturers manage allergens in their operations.

Elder Abuse Vulnerability and Risk Factors: Is Financial Abuse Different From Other Subtypes?

Elder abuse (EA) affects one in six older adults, and financial EA, a common subtype, severely impacts victims and society. Understanding victim vulnerability and perpetrator risk factors is essential to EA prevention and management. The limited existing evidence about these factors in relation to EA types suggests that financial EA is different. In a cross-sectional quantitative analysis of secondary data (N = 1,238), we investigated EA vulnerability and risk factors, and victim-perpetrator family relationship, with respect to different EA types (financial only, financial co-occurring with other types, and nonfinancial abuse). Financial abuse-only cases had the lowest prevalence of vulnerability and risk factors. Most of these factors, and a familial relationship, were significantly more common in cases involving other EA types. Findings indicate that financial abuse, occurring in isolation, is distinct from other EA types. Risk assessment and future research should consider financial abuse separately to other EA forms.

Spent fowl as a source of unintentional egg proteins exposure in Canadian food products.

The occurrence of egg proteins in products containing spent fowl manufactured under current practices was studied to assess the risk these food products may pose to egg-allergic consumers and to determine if Precautionary Allergen Labelling (PAL) was recommended. Spent fowl slaughtering and processing operations in 2 Canadian facilities were observed. Raw hen pieces (n = 134), coming from 2 facilities, and intermediate and processed products containing spent fowl (n = 57), coming from one facility, were analyzed using ELISA. All samples tested positive for egg proteins. Raw pieces were tested using a qualitative method (i.e., swabbing); estimated egg proteins concentrations suggest the presence of highly contaminated samples (>600 mg/kg in 2 hen wing samples). Swabbing was found to be efficient for rapid detection of eggs in raw hen pieces, but not for quantification. A comparison between swab and grind results showed that egg proteins concentration is underestimated by at least a factor 2 for whole carcasses and a factor 10 for breast, wings and drumsticks, when using the swab protocol. For intermediate and processed products, quantitative measurements indicate that egg protein levels were below 16 mg/kg. Additionally, 88 water samples from chiller tanks were analyzed and indicate that this step could be the cause of the global contamination observed with an increase in egg protein concentrations overtime during the production schedule. As egg contamination is not adequately controlled under the current good production practices, the use of PAL would be recommended for raw spent fowl products.

Validation of the RIDASCREEN® Peanut for Determination of Peanut Protein in Cookies, Milk Chocolate, Ice Cream, Trail Mix, Puffed Rice Cereals, and Granola Bar: AOAC Performance Tested MethodSM 112102.

BACKGROUND: Regulations in many countries worldwide prescribe that peanut must be listed on food labels as a cause of food allergies. Re-evaluated voluntary incidental trace allergen labelling (VITAL) values for peanut revealed the eliciting dose (ED01) value-at which 99% of all peanut-allergic individuals will not react-is 0.2 mg peanut protein. OBJECTIVE: Validation of a sandwich ELISA based on monoclonal antibodies to detect peanut proteins. METHODS: Non-processed and processed samples are extracted by an easy procedure at 60°C within 10 min. The measurement range is between 0.75 and 6 mg/kg peanut using a national institute of standards and technology (NIST) reference material as calibrator. RESULTS: The system shows no cross-reactivity against 91 different food commodities. The LOD was 0.15 mg/kg for food matrixes such as cookies, milk chocolate, ice cream, trail mix, puffed rice cereal, and granola bar. LOQ was verified at a level of 0.75 mg/kg. Recovery studies with incurred milk chocolate and ice cream revealed consistent recoveries between 67 and 85%. Mean recoveries for incurred cookies depend on the baking temperature and time and ranged from 60 to 109%. Repeatability was between 5.2 and 12.3%, whereas relative intermediate precision was between 6.4 and 13.0%. The results for incurred cookies and milk chocolate in the independent laboratory study showed mean recoveries between 99 and 104% with RSDs between 3.56 and 19.5% under repeatability conditions. CONCLUSION: The results from the in-house validation study and the independent lab confirmed that the method is accurate and in accordance with requirements laid down in Standard Method Performance Requirement 2017.020. HIGHLIGHTS: RIDASCREEN® Peanut quantifies proteins from peanut in a wide range of food categories.
