Conhecimento de manipuladores de alimentos sobre higiene e condições sanitárias na produção de comida japonesa / Food handlers’ hygiene knowledge and sanitary conditions in the japanese food production

A comida japonesa consiste principalmente de frutos do mar crus e arroz e apresenta riscos à saúde quando inadequadamente preparados ou armazenados. O objetivo deste estudo foi avaliar as condições higiênico-sanitárias em estabelecimentos que produzem comida japonesa e avaliar o conhecimento de manipuladores de alimentos que trabalham nesses estabelecimentos sobre alimentos seguros. Participaram do estudo seis estabelecimentos que produziam comida japonesa e estavam localizados em um município da região central de Minas Gerais (nomeados por letras de A a F). Uma lista de verificação de boas práticas com base na Resolução da Diretoria Colegiada 216 (RDC 216) e um questionário para avaliar o nível de conhecimento dos manipuladores foram aplicados nesses estabelecimentos. Foi verificado que apenas os estabelecimentos A, B e C foram classificados como adequados em relação às condições higiênico-sanitárias (com 76,6%, 80,9% e 78,7% dos itens cumpridos, respectivamente) e os estabelecimentos D, E e F foram classificados como adequados com restrição (D= 70,2%, E= 66% e F= 53% dos itens cumpridos, respectivamente). O conhecimento dos manipuladores foi classificado como deficiente, pois todos acertaram menos de 50% das questões. Os resultados mostram a necessidade de fornecer treinamento periódico sobre práticas de higiene adequadas aos manipuladores, a fim de prevenir doenças transmitidas por alimentos.

Daily Habits of Brazilians at Different Moments of the COVID-19 Pandemic

Background: The COVID 19 pandemic impacted the health and well-being of different populations around the world. The aim of this study is to investigate the changes in the daily habits of Brazilians before and during two moments of the COVID-19 pandemic. Methods: A longitudinal study in which an online questionnaire (sleeping time, alcohol consumption, smoking, use of screen devices, physical activity, and dietary patterns) was applied at three moments. Results: The frequency of alcohol consumption, smoking, and sleep hours did not change significantly at different times. For the number of alcoholic beverages, there was a reduction in consumption from T0 to T1 and an increase from T1 to T2. There was a significant increase in hours of screen device use from T0 to T1, remaining high at T2. Finally, the level of physical activity in minutes reduced from T0 to T1, returning to base levels at T2. As for eating habits, there was an increase in the frequency of consumption of instant meals, fast food, and sweets at the first moment, with a significant reduction at the second moment. The consumption of legumes, milk and dairy products, bakery products, and meats was higher at T2. Conclusions: Some habits returned to or approached T0 levels. However, other habits remained unchanged, such as screen time and frequency of consumption of some food groups, throughout the last evaluation

Effect of probiotics on the development of dimethylhydrazine-induced preneoplastic lesions in the mice colon

PURPOSE: To determine the effect of probiotics on the development of chemically induced (1, 2-dimethylhydrazine) colonic preneoplastic lesions, in mice. METHODS: The animals were divided into five groups. The control group was injected with carcinogen alone and the other groups also received probiotics (1- Lactobacillus delbrueckii UFV-H2b20; 2- Bifidobacterium animalis var. lactis Bb12; 3- L. delbrueckii UFV-H2b20 plus B. animalis var. lactis Bb12; and 4- Saccharomyces boulardii) administered orally in drinking water throughout fourteen weeks. RESULTS: Consumption of lactobacilli and bifidobacteria alone resulted in a significant reduction of the total number of aberrant crypt foci (55.7% and 45.1%, respectively). Significant reduction in the number of these small foci (<3 aberrant crypts) was only observed in the group treated with lactobacilli (52.2%) in comparison to control group. The number of larger foci (>3 aberrant crypts) crypts had no significant reduction. CONCLUSION: L. delbrueckii UFV-H2b20 and B. animalis var. lactis Bb12 administered alone protect colonic preneoplastic lesions in mice, while the combined treatment of these bacteria and the administration of S.boulardii were not effective in reducing such colonic lesions
