ABSTRACT
Introducción: En el Perú, el 90% de trigo es importado y su alta cotización internacional (390 dólares TN-1) implica la necesidad de encontrar sustitutos principalmente en productos de panificación que en su mayoría son formulados a base de trigo. Las harinas provenientes de frijol garbanzo y maíz amarillo, pueden mostrarse como alternativas potenciales y contribuir a mejorar el valor nutricional y sensorial del alimento. Objetivo: Desarrollar y evaluar nutricionalmente y sensorialmente una galleta tipo soda sustituyendo parcialmente la harina de trigo (HT) por harina de maíz amarillo (Zea mays) nixtamalizado (HMN) y garbanzo (Cicer arietinum) (HG). Materiales y métodos: Se realizaron tres formulaciones, F1: 70% HT, 20% HMN y 10% HG, F2: 70% HT, 10% HMN y 20% HG y F3: 50% HT, 20% HMN y 30% HG, la muestra control contenía 100% harina de trigo. Se determinaron contenido de proteínas, grasa y carbohidratos por análisis proximal, así como sabor y textura en el análisis sensorial. Resultados: F3 presentó mayor contenido de proteínas (11,88%), grasa (3,70%), y carbohidratos (71,08%), mientras que F2 fue percibido por los panelistas con un sabor moderadamente salado y de textura crujiente. Conclusiones: Se concluye que una sustitución mayor al 50% de harina de trigo por harina de leguminosa y harina de maíz nixtamalizada permite obtener galletas con alto contenido proteico y de textura similar a una galleta tipo soda comercial(AU)
Introduction: In Peru, 90% of wheat is imported and its high international price ($390 per TN) implies the need to find substitutes mainly in baking products that are mostly formulated with wheat. Flours from chickpeas and yellow corn can be shown as potential alternatives and contribute to improving the nutritional and sensory value of the food. Objective: Develop and nutritionally and sensorially evaluate a soda cracker partially substituting wheat flour (HT) with nixtamalized yellow corn flour (Zea mays) (HMN) and chickpea (Cicer arietinum) (HG). Material and methods: Three formulations were made, F1: 70% HT, 20% HMN and 10% HG, F2: 70% HT, 10% HMN and 20% HG and F3: 50% HT, 20% HMN and 30% HG, the control samplecontained 100% wheat flour. Protein, fat and carbohydrate content were determined by proximal analysis, as well as flavor and texture were determined in sensory analysis. Results: F3 presented a higher content of proteins (11.88%), fat (3.70%), and carbohydrates (71.08%), while F2 was perceived by the panelists as having a moderately salty flavor and crunchy texture. Conclusions: It is concluded that a substitution of more than 50% of wheat flour by leguminous flour allows obtaining crackers with high protein content and a texture similar to a commercial soda cracker(AU)

El suero lácteo y la moringa poseen alto valor nutricional; sin embargo, su uso en la elaboración de productos alimenticios es una alternativa viable pero poco utilizada. Objetivo. Elaborar una galleta fortificada por sustitución parcial de harina de moringa (HM) y polvo de suero lácteo (PSL). Materiales y métodos. Durante septiembre-diciembre 2021, se desarrollaron cuatro formulaciones con sustitución parcial de harina de trigo por HM y PSL (F0=100:0:0; F1=90:5:5; F2=80:10:10; F3=70:15:15). La aceptación del producto se determinó mediante una evaluación sensorial considerando los atributos sabor, olor, color, textura y aceptación general. Se realizó el análisis químico proximal a la HM, al PSL, a la formulación de mayor aceptación y a F0. Se compararon los distintos parámetros químico proximales y de aceptación mediante una anova de una vía, seguido de una prueba de comparación de medias de Tukey (p<0,05). Resultados. Conforme se incrementa el porcentaje de sustitución de harina de trigo por HM y PSL se obtiene menor aceptación de las galletas, siendo F1 la más aceptada. F1 registró un contenido proteico de 6,90±0,04%, significativamente mayor al observado en F0. Conclusiones. La buena aceptabilidad de F1 indica que la sustitución parcial por HM y PSL no influyen en su aceptación; además, F1 mostró un enriquecimiento de proteinas, lípidos y cenizas, así como contenido adecuado de humedad y carbohidratos(AU)
Introduction. Whey and moringa have high nutritional value; however, their use in the production of food products is a viable but rarely used alternative. Objective. To make a biscuit fortified by partial substitution of moringa flour (MF) and whey powder (WP). Materials and methods. During September-December 2021, four formulations were developed with different degrees of partial substitution of wheat flour for MF and WP (F0=100:0:0; F1=90:5:5; F2=80:10:10; F3=70:15:15). The acceptance of the product was determined through a sensory evaluation considering the attributes taste, odor, color, texture and general acceptance. A proximal chemical analysis was performed on the MF, WP, the most widely accepted formulation and F0. Proximal chemical parameters and acceptance attributes were compared using a one-way anova, followed by a Tukey mean comparison test (p<0.05). Results. As the percentage of substitution of wheat flour by MF and WP increases less acceptance of the biscuits is obtained, with F1 as the most accepted formulation. F1 registered a protein content of 6.90±0.04%, significantly higher than that observed in F0. Conclusions: The good acceptability of F1 indicates that the partial substitution of wheat flour for MF and WP do not influence its acceptance; in addition, F1, showed an enrichment of protein, lipid and ash, as well as adequate moisture and carbohydrate content(AU)

To investigate the common specific immunoglobulin E(sIgE) in children with eczema and urticaria, compare the allergies in children with different diseases, genders and ages, and provide the scientific basis for the prevention, diagnosis and treatment. A retrospective study was conducted to analyze the children who were suspected of eczema and urticaria and tested for serum sIgE in the Tianjin Children's Hospital from December 2019 to August 2021. A total of 8 092 serum samples were tested for ten food allergens and ten inhaled allergens. The method was the enzyme-linked immune capture assay. The allergen epidemiological characteristics were statistically analyzed by Chi square test based on the children's characteristics and factors such as different sexes and ages and by the mass data. The results showed that the positive rate of eczema was 64.42%(5 213/8 092), and the urticaria was 35.58%(2 879/8 092). The positive rate of specific IgE was 66.65%(5 393/8 092), the food allergens was 61.74%(4 996/8 092), and the inhaled allergens was 34.85%(2 820/8 092). The top three positive rates of food allergens were egg 46.65%(3 775/8 092), milk 32.64%(2 641/8 092) and wheat flour 15.08%(1 220/8 092). The top three positive rates of inhaled allergens were house dust 21.40%(1 732/8 092), Alternaria 11.78%(953/8 092) and Dermatophagoides farinae 7.33%(593/8 092). The positivity of food allergens and inhaled allergens was significantly different in different age groups. The positive rates of food allergens in different age groups were 48.92%(947/1 936) in<1 year old, 72.28%(2 680/3 708) in 1-3 years old, 64.58%(919/1 423) in 4-6 years old and 43.90%(450/1 025) in>6 years old. The positive rates of inhaled allergens in different age groups were 17.67%(342/1 936) in<1 year old, 36.35%(1 348/3 708) in 1-3 years old, 46.38%(660/1 423) in 4-6 years old and 45.85%(470/1 025) in>6 years old. The top six positive rates of allergens of eczema were the same with urticaria, which were egg, milk, house dust, wheat flour, Alternaria and Dermatophagoides farinae. The allergens (greater than or equal to grade 4) differed in children with eczema and urticaria. Moreover, there were significant differences in the positive rates of Alternaria, egg, wheat flour, crab and shrimp. In conclusion, this study can reflect the epidemic characteristics of allergens in children with eczema and urticaria to a certain extent. There were significant differences in the positive rates of allergens between different age groups. It is necessary to reasonably avoid the high-risk allergens according to the epidemiological characteristics and clinical symptoms, which provide valuable information for the prevention, diagnosis and treatment of allergic diseases.

Abstract Among several fruits, mangaba (Hancornia speciosa Gomes), it aroused the interest of producers and consumers due to its attractive sensory characteristics and health beneficial properties (high nutritional value and presence of bioactive substances), thus, this work evaluates the nutritional factors of the flour residue of mangaba processing that is despised by the food industry, and the influence of temperature on its production. The mangaba processing residue was splited in two main groups: in natura sample (control), and other for preparation of flour that was dried at 50 °C and divided into two other groups: treatment A (flour with roasts at 110 °C and 130 °C) and treatment B (flour from drying at 50 °C). The nutritional characteristics of flours were analyzed considering the chemical parameters: pH, titratable total acidity and soluble solids, in addition to the determination of moisture content, total lipids, total dietary fiber and ash, total energy value, antioxidant activity, phytochemical screening, quantification of phenolic compounds and flavonoids, as well as technological functional properties (water absorption index (WAI), water solubility index (WSI), milk absorption index (MAI) and milk solubility index (MSI) and oil absorption index (OAI). The results showed that the bioactive compounds present in the extracts do not have significant properties of acting as free radical kidnappers. The heat treatment, performed in the flour of mangaba processing residues, influenced the nutritional factors and properties of absorption and solubility, which showed statistical differences. These results show that the flour is a viable alternative for the energy enrichment of diets, contributing to the development of new products, the reduction of the disposal of these residues and consequently to the minimization of the environmental impact.
Resumo Dentre as diversas frutas a mangaba (Hancornia speciosa Gomes), despertou interesse de produtores e consumidores devido às suas características sensoriais atrativas e propriedades benéficas à saúde (elevado valor nutricional e presença de substâncias bioativas), assim, o trabalho avaliar os fatores nutricionais do resíduo da farinha de processamento de mangaba que é desprezado pela indústria alimentícia e, a influência da temperatura na sua produção. O resíduo de processamento da mangaba foi dividido em dois lotes, sendo um deles utilizado para as análises in natura (amostra controle) e o outro para a confecção da farinha que foi seca a 50 °C, e dividida em dois lotes: tratamento A (farinha com torras a 110 °C e 130 °C) e no tratamento B (farinha oriunda da secagem a 50 °C). Analisou-se as características nutricionais de farinhas considerando os parâmetros químicos: pH, acidez total titulável e sólidos solúveis, além da determinação do teor de umidade, lipídios totais, fibra alimentar total e cinzas, valor energético total, atividade antioxidante, triagem fitoquímica, quantificação de compostos fenólicos e flavonoides, bem como as propriedades funcionais tecnológicas (índice de absorção de água (IAA), índice de solubilidade em água (ISA), índice de absorção de leite (IAL) e índice de solubilidade em leite (ISL) e índice de absorção de óleo (IAO). Na análise foi inferido que os compostos bioativos presentes nos extratos não possuem propriedades significativas de agir como sequestradores de radicais livres. O tratamento térmico, realizado na farinha de resíduos de processamento de mangaba, influenciou nos dados dos fatores nutricionais e das propriedades de absorção e solubilidade, os quais apresentaram diferenças estatísticas. Estes resultados credenciam a farinha como uma alternativa viável para o enriquecimento energético de dietas, contribuindo para o desenvolvimento de novos produtos, a redução do descarte desses resíduos e consequentemente para a minimização do impacto ambiental.

Os cereais são uma importante fonte alimentícia e econômica, dentre eles se destaca o trigo e sua farinha. Durante o cultivo, visando o controle de pragas, frequentemente são utilizados os agrotóxicos, porém seu uso abusivo pode acarretar danos à saúde humana e ao meio ambiente. O trabalho teve como objetivo avaliar a presença de resíduos de agrotóxicos em amostras de farinha de trigo comercializadas no estado de São Paulo, utilizando o método QuEChERS (Rápido, Fácil, Barato, Efetivo, Robusto e Seguro) modificado, seguido de análise por CG-EM/EM e CLUE-EMAR para identificação e quantificação. No total, 124 ingredientes ativos (i.a.) estavam dentro dos critérios de aceitação para linearidade, limites de detecção e quantificação, exatidão e precisão (intervalo de confiança de 95%; k = 2). Os resultados de 25 amostras indicaram a presença de bifentrina, fenitrotiona, clorpirifós, deltametrina, lambda-cialotrina e pirimifós-metílico em farinha de trigo comum e os quatro últimos i.a. também foram detectados em farinha de trigo orgânica. O pirimifósmetílico foi detectado em 92% das amostras. Os i.a. encontrados nas amostras estavam abaixo do Limite Máximo de Resíduos (LMR) estabelecidos pela Agência Nacional de Vigilância Sanitária (Anvisa) para farinha de trigo e as amostras foram consideradas próprias para o consumo (AU).
Cereals are an important economic factor and food source, which wheat and its flour stand out. Pesticides are often employed to control harmful organisms, but their abusive use can cause damage to human health and the environment. This study aimed to evaluate the presence of pesticide residues in wheat flour samples commercialized in the state of São Paulo Brazil, using the modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method, followed by GC-MS/MS and UHPLC-HRMS analysis for identification and quantification. Thus, 124 active ingredients (a.i.) were within acceptable criteria for linearity, limits of detection and quantification, accuracy (trueness), and precision (95% confidence level; k = 2). The results for 25 wheat flour samples showed the presence of bifenthrin, fenitrothion, chlorpyrifos, deltamethrin, lambda-cyhalothrin, and pirimiphos-methyl, and the last four a.i. were also detected in organic wheat flour. Pirimiphos-methyl was detected in 92% of all samples. All compounds were found below the Maximum Residue Levels (MRL) established by Brazilian Health Regulatory Agency (Anvisa) for wheat flour and the samples were considered suitable for consumption (AU).

Folic acid belongs to the group of water-soluble B vitamins and naturally exists in multiple forms in a wide variety of foods such as legumes, vegetables, liver, and milk (Iyer and Tomar, 2009; Lyon et al., 2020). It is involved in many biochemical reactions critical for cell division, such as purine and pyrimidine biosynthesis, DNA/RNA biosynthesis, and amino acid metabolism (Iyer and Tomar, 2009). Mammals cannot synthesize folic acid and thus they must acquire it from food. Although folic acid is ubiquitous in foods, folic acid deficiency still often occurs due to various causes such as unhealthy diet (Hildebrand et al., 2021; Iimura et al., 2022), disease-related malabsorption (Arcot and Shrestha, 2005), medication-related depletion (Arcot and Shrestha, 2005), or vitamin B12 deficiency (Fishman et al., 2000). Folic acid deficiency has been associated with several health problems, such as anemia (Carmel, 2005; Bailey and Caudill, 2012), cancer (Duthie, 1999), cardiovascular diseases (Wald et al., 2002), neural tube defects in newborns (van der Put et al., 2001), neuropsychiatric dysfunction (Shea et al., 2002), depression (Falade et al., 2021), inflammatory diseases (Suzuki and Kunisawa, 2015; Jones et al., 2019), and eye diseases (Sijilmassi, 2019). To prevent folic acid deficiency, its daily intake (400 μg/d) has been recommended for adults in the European Union, and its increased intake (600 μg/d) is advised for women before and during pregnancy (FAO/WHO, 2002; IOM, 2004). The New Zealand government mandated the fortification of non-organic wheat flour with folic acid in July 2021, and the UK government mandated the fortification of non-wholemeal wheat flour with folic acid in September 2021 (Haggarty, 2021).

A fim de atender à demanda do público que atualmente busca por alimentos mais saudáveis, as indústrias têm procurado alternativas que possibilitem a aplicação de ingredientes que agreguem valor nutricional aos produtos. A redução de gorduras saturadas e trans em produtos alimentícios, bem como a inserção de cereais ou farinhas nutricionais, vem sendo aplicadas em produtos de panificação. Biscoitos recheados possuem como bases geralmente biscoitos à base de farinha de trigo. O objetivo foi desenvolver formulação de biscoitos recheados com substituição de gordura vegetal por organogel no recheio e de farinha de trigo por farinha de sorgo no biscoito, a fim de agregar valor nutricional ao produto. Foram desenvolvidos biscoitos recheados: 1) recheio controle e com substituição da gordura vegetal dos recheios por organogel elaborado com sistema emulsionado (colágeno + óleo vegetal + água), a fim de diminuir concentrações de gorduras saturadas e trans. 2) para a base elaborouse biscoitos controle (farinha de trigo) e com substituição parcial e total de farinha de trigo por farinha de sorgo em 50% (50FS) e 100% (100FS). Foram conduzidas nos recheios e das bases dos biscoitos análises físicas e físico-químicas (textura, atividade de água, cor, composição centesimal e reologia) para avaliação e para análise de estabilidade de 6 semanas. Os resultados apresentaram que o biscoito 50FS obteve melhor valor de textura (Controle: 16,09 ± 1,28 N; 50FS: 19,63 ± 5,68 N e 100FS: 10,09 ± 0,65 N) e menor teor de atividade de água (Semana 01: 0,327±0,01 e Semana 06: 0,389 ± 0,00) do que o biscoito controle, durante análise de estabilidade. O biscoito 100FS apresentou coloração mais avermelhada. Os biscoitos 50FS e 100FS apresentaram maior teor proteico do que o controle (Controle: 5,37 ± 0,23 %; 50FS: 5,64 ± 0,49 % e 100FS: 5,75 ± 0,49 %). O recheio com organogel apresentou maior dureza (N) durante análise de estabilidade do que o recheio controle (Semana 6 Organogel: 6,81±1,48; Controle: 4,29±0,38). Os parâmetros de adesividade, coesividade e gomosidade do recheio com organogel não apresentaram diferenças significativas (p > 0,05). Os valores de atividade de água da formulação com organogel foram mais altos do que o recheio controle (Semana 6 Organogel: 0,730±0,00; Controle: 0,555±0,01). O valor de L* foi maior para o recheio controle, apresentando coloração mais amarelada do que a formulação com organogel. O recheio com organogel apresentou redução de 65 % do teor lipídico e aumento do teor proteico. Os recheios controle, com organogel e de mercado apresentaram comportamento tixotrópico durante a avaliação reológica, sendo que o produto de mercado teve comportamento próximo à formulação controle, com recuperação quase total da estrutura. Foram desenvolvidos cinco produtos, sendo três inovadores com valor nutricional agregado, atendendo às legislações vigentes, vida útil mínima de 6 semanas e ao apelo do mercado atual, podendo ser comercializados como biscoito recheado
In order to satisfy the demand of the public that is currently looking for healthier foods industries have been looking for alternatives that allow the application of ingredients that add nutritional value to the products. The reduction of saturated and trans fats in food products, as well as the insertion of cereals or nutritional flours, has been applied in bakery products. Filled cookies are usually based on wheat flour. The objective was to develop a formulation of filled cookies with replacement of vegetable fat for organogel in the filling and wheat flour for sorghum flour in the biscuit, in order to add nutritional value to the product. In this study, cookies filled with vegetable fat and wheat flour were used as a control where: 1) filling was replaced by organogel elaborated with an emulsified system (collagen + vegetable oil + water); and 2) base was prepared with partial and total replacer of wheat flour for sorghum flour in 50% (50FS) and 100% (100FS). Physical and physicochemical analyzes (texture, water activity, color, proximate composition and rheology) were carried out on the fillings and bases of the biscuits for evaluation and for the stability analysis of 6 weeks. The results showed that the 50FS cookies had a better texture value (Control: 16,09±1,28 N; 50FS: 19,63±5,68N and 10,09±0,65 N) and lower content of water activity (Week 1: 0,327±0,01 and Week 6: 0,389±0,00) than the control cookie during stability analysis. The 100FS had a more reddish color. The 50FS and 100FS cookies had a higher protein content than the control (Control: 5,37±0,23 %; 50FS 5,64±0,49 %). The fillings with organogel showed a higher hardness (N) than the control during stability analysis (Week 6 Organogel: 6,81±1,48; Control: 4,29±0,38). The parameters of adhesiveness, cohesiveness and guminess of the filling with organogel showed no significant differences (p> 0.05). The water activity values of the organogel formulation were higher than the control filling (Week 6 Organogel: 0,730±0,00; Control: 0,555±0,01). The value of L * was higher for the control filling, showing a more yellowish color than the formulation with organogel. The filling with organogel showed a 65% reduction in lipid content and an increase in protein content. The control, organogel and market fillings showed a thixotropic behavior in the rheological evaluation, and the market product had a behavior close to the control formulation, with almost total recovery of the structure. Five products were developed, three of which were innovative with added nutritional value, in compliance with current legislation, a minimum shelf life of 6 weeks, which can be sold as a stuffed cookies.

Abstract Six different bread wheat genotypes; two Egyptian commercial varieties (control); Giza-168 and Gemmeiza-11, and four promising lines; L84 and L148, resulted via hybridization and M10 and M34 via radiation mutation program) were rheologically evaluated using extensograph and for protein, analysis using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The radiation mutant M10 and M34 had the highest maximum resistance which is a very good indicator of strong gluten. The amount of gluten content was higher in M10, L148, and M34 compared to the control samples Gz168 and Gm11. Sulfide amino acids (CYS and MET) are slightly higher in M10. The electrophoretic results and amino acid analyzers show that the best technological quality was exhibited by M10. Radiation mutants wheat genotypes have a protein with good characteristics, mainly gluten which is significantly higher compared to control samples. The rheological properties measured as extensograph and gel electrophoresis were much better in irradiated lines M10 and M34.

Os mutantes de radiação M10 e M34 apresentaram a maior resistência máxima, o que é um indicador muito bom de glúten forte. A quantidade de glúten foi maior em M10, L148 e M34 em comparação com as amostras de controle Gz168 e Gm11. Os aminoácidos sulfurados (CYS e MET) são um pouco mais altos no M10. Os resultados eletroforéticos e analisadores de aminoácidos mostram que a melhor qualidade tecnológica foi exibida pelo M10. Os genótipos de trigo mutantes da radiação possuem uma proteína com boas características, principalmente o glúten, que é significativamente maior em comparação às amostras do grupo controle. As propriedades reológicas medidas, como extensógrafo e eletroforese em gel, foram muito melhores nas linhas irradiadas M10 e M34.

Introducción. El enriquecimiento de la harina de trigo es una de las estrategias de salud pública recomendadas para prevenir las deficiencias de micronutrientes, entre ellos el hierro. El objetivo de este trabajo fue determinar el contenido de hierro en harina de trigo enriquecida y sus derivados, y la contribución de estos a las recomendaciones nutricionales en niños. Población y métodos. Estudio observacional, analítico, de corte transversal, basado en la metodología de estudio de dieta total. Se analizaron la harina de trigo enriquecida (según la ley 25630) y sus derivados más consumidos. Para seleccionar los alimentos, se realizó un cuestionario de frecuencia de consumo y recordatorio de 24 horas a los padres de niños con edades entre 6 meses y 7 años. Se determinó la concentración de hierro en los alimentos mediante absorción atómica y se evaluó su contribución al requerimiento promedio estimado. Resultados. La harina enriquecida y sus derivados tuvieron la cantidad de hierro esperada, excepto el pan francés y el pan rallado. La contribución a los requerimientos de hierro de los alimentos evaluados fue el 7 % en niños de 6 meses a 1 año, el 81 % en el grupo de 1 a 3 años y el 45 % en los mayores de 4 años. Conclusiones. Excepto el pan francés y el pan rallado, las harinas y sus derivados analizados presentaron el nivel de enriquecimiento esperado. El consumo de estos alimentos no aporta cantidades significativas de hierro en los lactantes, pero sí en los niños mayores de 1 año.
Introduction. Wheat flour enrichment is a public health strategy recommended to prevent micronutrient deficiencies, including iron deficiency. The objective of this study was to determine iron content in enriched wheat flour and flour products and their contribution to nutritional recommendations for children. Population and methods. Observational, analytical, cross-sectional study based on the total diet study method. Enriched wheat flour (as per Law no. 25630) and the most frequently consumed flour products were analyzed. Products were selected using a questionnaire on the frequency of food intake and a 24-hour recall interview with the parents of children aged 6 months to 7 years. Food iron levels were determined based on atomic absorption spectrometry and their contribution to the estimated average requirement was assessed. Results. Enriched flour and flour products showed the expected iron amount, except for French bread and breadcrumbs. The contribution of studied products to iron requirements was 7 % in children aged 6 months to 1 year, 81 % in those aged 1-3 years, and 45 % in those older than 4 years. Conclusions. Except for French bread and breadcrumbs, studied flour and flour products showed the expected enrichment level. The consumption of this type of food does not provide significant amounts of iron to infants, but it does to children older than 1 year.

BACKGROUND@#International Labour Organization (ILO) report indicates more than 2.4 million workers die from work-related diseases and accidents each year. Work-related respiratory ailments related to airborne particulate matter such as flour dust are responsible for about 386,000 deaths and 6.6 million illness-adjusted life years. Even though exposure to flour dust together with the extreme expansions of flour mill sectors is a priority health concern, extent of the problem is little investigated in Ethiopia. The aim of this study was to evaluate the magnitude and risk factors of work-related respiratory symptoms among flour mill workers in Bahir Dar City, Ethiopia.@*METHODS@#This study employed a comparative cross-sectional survey of 560 samples (280 exposed group from flour mill workers and 280 unexposed group from office workers) with a stratified random sampling technique. The study was conducted from March to April 2019 in Bahir Dar City, Northwest Ethiopia. We used the British Medical Research Council (BMRC) questionnaire to assess work-related respiratory symptoms. The questionnaire was pretested and interview administered to collect data. Binary logistic regression analysis was fitted to evaluate significant factors of respiratory symptoms at a < 0.05 p value. Adjusted odds ratio (AOR) with a confidence interval (CI) of 95% was calculated to determine a strength of association.@*RESULTS@#All the sampled participants had fully responded to the interview. The median age of exposed and unexposed groups was 28.5 interquartile range (IQR, 20) and 31 (IQR, 15) years, respectively. The prevalence of work-related respiratory symptoms among flour mill workers was substantially higher than that of among controls, 63.9% and 20.7%, respectively (Χ@*CONCLUSION@#Respiratory symptoms emanating from exposure to various flour dusts were significantly higher among flour mill workers than among the control group. Therefore, we recommend the need to effectively implement health and safety programs that account for the reduction of dust at a source, use of engineering controls (e.g., provision of adequate ventilation systems), use of administrative measures (e.g., training program and health surveillance) and provision of a suitable personal protective equipment (PPE). Furthermore, it is vital to integrate workplace health and safety programs to the wider public health policies and strategies to effectively mitigate the burden of work-related respiratory conditions. We also encourage future studies to evaluate concentration of flour dusts combined with physical examinations to establish plausible associations of respiratory symptoms with dusts of flour mill-related origin.
