The COVID-19 pandemic caused by the SARS-CoV-2 virus brought additional challenges to the Food and Nutrition Service, so in addition to meeting the hygienic-sanitary conditions of food, companies now need to incorporate new manufacturing practices. foods that aim to preserve the health of workers as well as consumers. In this context, this study aimed to carry out a literature review on technical recommendations for good food manufacturing practices related to the prevention of COVID-19 and prepare a checklist to facilitate the identification of failures, assess risk COVID-19 transmission in food services and guide how to adapt the good manufacturing practices manuals. Based on technical notes (NT) 47, 48 and 49 of 2020 that were edited by ANVISA, based on the standards of the World Health Organization (WHO), a questionnaire was created containing 100 questions in the various categories of the food production sector, such as physical structure/building, hand washing conditions, general worker protection measures, material storage area, personal hygiene conditions, food storage area, company personnel, customer service area, preparation area, portioning and distribution area, food consumption area for workers, area for reception and food services received and food delivery services. In this way, we understand that biosafety measures must be adopted from the update of the manuals of good manufacturing practices in food services, and, to support this action, we propose the use of the checklist in the appendix to identify non-conformities related to the prevention of COVID -19.

A pandemia da COVID-19 causada pelo vírus SARS-CoV-2 trouxe desafios adicionais ao Serviço de Alimentação e Nutrição (SAN), pois, além de atender as condições higiênicas sanitárias dos alimentos, as empresas agora precisam incorporar novas práticas que visem preservar a saúde das pessoas. Nesse contexto, esse estudo buscou realizar uma revisão da literatura sobre as recomendações técnicas de boas práticas de fabricação de alimentos relacionadas com a prevenção da COVID-19 e elaborar uma lista de verificações (check-list) para facilitar a identificação de falhas, avaliar risco de transmissão da COVID-19 nos serviços de alimentação e orientar as adaptações dos manuais de boas práticas de fabricação. Com base nas notas técnicas vigentes no Brasil e baseadas nas diretrizes da Organização Mundial de Saúde (OMS), foi elaborado um questionário contendo 100 perguntas nas diversas categorias do setor de produção de alimentos. Dessa maneira, entendemos que medidas de biossegurança devem ser adotadas a partir da atualização dos manuais de boas práticas de fabricação nos serviços de alimentação, e, para apoiar essa ação, propomos a utilização do checklist em apêndice para identificar as inconformidades relacionadas a prevenção da COVID-19.

Detection of tuberculosis in cattle relies on the intradermal tuberculin test (ITT), but a definitive diagnosis requires identification of the pathogen after the animal is slaughtered. DNA in nasal swabs from 50 cows was analyzed by m-PCR, targeting for the RvD1-Rv2031c and IS6110 sequences. M. bovis was identified in two of 34 tuberculous cows (5.9%). The use of mPCR of nasal swabs as an in vivo diagnostic tool for bovine tuberculosis is suggested.

Colônias isoladas a partir de lesões sugestivas de tuberculose bovina foram testadas pela reação múltipla em cadeia da polimerase, usando oligonucleotídeos direcionados para as seqüências genômicas RvD1Rv2031c e IS6110, específicas para M. bovis e para o complexo Mycobacterium tuberculosis, respectivamente. A m-PCR identificou, com sucesso, 88,24% das colônias isoladas como M. bovis.

Isolates from suggestive bovine tuberculosis lesions were tested by a multiplex polymerase chain reaction (m-PCR) targeting for RvD1Rv2031c and IS6110 sequences, specific for M. bovis and Mycobacterium tuberculosis complex respectively. The m-PCR successfully identified as M. bovis 88.24% of the isolates.
