Item Avaliação de boas práticas de fabricação em casas de bolos no município da Região Metropolitana do Recife(2019-12-13) Souza, Vitória Brenda do Nascimento; Padilha, Maria do Rosário de Fátima; http://lattes.cnpq.br/9689966677422344; http://lattes.cnpq.br/6822111679253379Item Concentração de elementos-traço chumbo (Pb) e cobre (Cu) em tecidos de Chelonia mydas (Linnaeus, 1758) no Litoral Sul de Pernambuco, Nordeste do Brasil(2021-08-06) Queiroz, Emily Pereira de; Moura, Geraldo Jorge Barbosa de; Rodrigues, Midiã da Silva; http://lattes.cnpq.br/4953311636839935; http://lattes.cnpq.br/1348666346504103; http://lattes.cnpq.br/9237498056744804Between threats to sea turtles species is the contamination of marine enviroments caused by trace elements wich infiltrate into organisms through food, airways or skin and can be passed on by trophic levels. The species Chelonia mydas has coastal habits whose main diet item is seaweed, which had evidence of accumulation by trace elements. This work determined the concentrations of trace elements lead (Pb) and copper (Cu), in order to know the level of contamination of local individuals and the bioavailability of the elements in habitat. 43 samples of C. mydas liver and muscle organs from the southern coast of Pernambuco, Northeast Brazil, collected from November 2016 to November 2018 were used. The quantification was performed by an Inductively coupled plasma - optical emission spectrometry (ICP OES). Cu showed a greater amount in liver, while Pb was present in a higher concentration in muscle, not being detectable in liver. For Cu, the highest concentration found was 64,683 mg kg-1 (6,389–212,286) while for Pb it was 4,115mg kg-1 (1.4–7,424). The southern coast of Pernambuco showed higher concentrations than other Brazilian states and several areas around the world, showing how other threats to the species mask the impacts of these contaminants, whose accumulation mechanisms need further studies to be fully understood. The values found provide a basis for monitoring the species and contamination of the local habitat.Item Avaliação da cafeína no controle da infecção experimental de macrófago por Salmonella typhimurium(2019) Almeida, Ingrydt de Alcântara; Lima Filho, José Vitor Moreira; Tavares, Lethicia Souza; http://lattes.cnpq.br/4128808335995892; http://lattes.cnpq.br/9476972124107533; http://lattes.cnpq.br/6015462685217823Salmonellosis is an infectious disease transmitted mainly by foods contaminated with bacteria of the genus Salmonella, among them Salmonella enterica serotype Typhimurium, which can cause gastroenteritis until sepsis and septic shock in groups at risk. Organic compounds for pharmacological purposes are being increasingly tested. Among these compounds, caffeine (1,3,7-trimethylxanthine), one of the most used pharmacological and psychostimulant substances in the world. Severalstudies have demonstrated its role as a therapeutic adjunct, immunomodulator and adenosine receptor antagonist (ARs). In view of this, the objective was to evaluate the immunomodulatory potential of caffeine in peritoneal macrophages infected with Salmonella enterica Sor. Typhimurium. For this, in vitro tests were performed with cultures of macrophages exposed to caffeine concentrations to determine the degree of cytotoxicity of the compound; curative and preventive tests of cell viability, in order to evaluate cellular survival and quantification of intracellular bacteria, aiming to analyze the clearance of the pathogen from the intracellular medium. A direct antibacterial activity test was also carried out to evaluate the efficacy of caffeine in preventing the development of S. typhimurium. The results demonstrated that caffeine did not produce a toxic effect on the uninfected macrophages at the concentrations used, promoted a greater viability of the infected macrophages, but was not able to act as a direct bactericide. Caffeine contributed to the survival of macrophages infected with S. Typhimurium, having potential for the control of bacterial infections.Item Mastite subclínica causada por Staphylococcus aureus: impacto econômico e na saúde pública(2016) Rebouças, Rodolpho Almeida; Silva, Nivan Antônio Alves da; http://lattes.cnpq.br/3505011500604071; http://lattes.cnpq.br/9440496743455219Subclinical mastitis is a silent disease without macroscopic changes in milk or udder, being considered the disease that causes the greatest losses to dairy cattle. The losses caused by subclinical mastitis are significant, mainly due to the reduction in the production of the quarters, in addition there is a reduction in milk quality, interfering in the characteristics of this, important for the dairy products industry. Staphylococcus aureus is the main causative agent of this disease, being an important pathogen, also responsible for food poisoning. Foods involved in outbreaks and cases of staphylococcal food poisoning include raw milk, pasteurized milk and cheeses, with S. aureus being the most frequently isolated microorganism. Milk from cows with mastitis is the second food of animal origin in which there is greater percentage of isolation of Staphylococcus aureus Resistant Methicillin. Producers' awareness is extremely important to reduce the impacts caused by this disease, since, from the knowledge, measures can be taken to prevent and control the disease in the herds and consequently to produce a quality product, preventing it from causing problems. In view of this, this paper aims to elaborate a literature review on subclinical mastitis caused by S. aureus and its economic and public health impacts in order to support the preparation of didactic material for informative purposes for rural producers.Item Resíduos de antimicrobianos no leite e sua importância para a saúde pública(2018) Leite Júnior, Nitalmo; Mendonça, Carla Lopes de; http://lattes.cnpq.br/3128979736085796; http://lattes.cnpq.br/6476986476934876Food and nutrition security is the realization of the right of everyone to regular and permanent access to quality food in sufficient quantity and without compromising access to other essential needs, including health promotion and quality assurance biological, health, nutritional and technological aspects of food. Some of the actions aimed at ensuring food safety are concerned with the control of residual remnants in food. The presence of antimicrobial residues in drinking milk is a cause for great concern, since in addition to causing economic losses by interfering in the production of dairy products, it poses risk to consumer health, which may predispose to allergic reactions, genotoxic and carcinogenic responses, and favor the emergence of resistant bacteria. In order to draw attention to this theme, the objective of this work is to carry out a review of the literature on antimicrobial residues in milk intended for human consumption and its implications for public health. For this purpose, databases, books, public entities' websites, specialized legislation, as well as informational and journalistic material regarding the subject matter were consulted. Based on the literature consulted, the presence of antimicrobial residues in milk is an important public health problem, because although there are government control and inspection programs, as well as supporting legislation, several studies carried out in several brazilian states, including in Pernambuco, have detected the presence of this type of contamination, reaching levels beyond the limits established in the specific standards. It is necessary that this topic be approached as a State policy, with broad actions encompassing different spheres and with due attention to the control and inspection programs, in addition, producers should be oriented about the risks that are involved, as well as the preventive strategies Veterinary Medicine assumes an important role in the search for a more sustainable and professionally managed animal husbandry, based on preventive health strategies and the adequate and rational use of therapeutic resources, concerned above all with the health and well-being of consumers and with the promotion of Single Health.Item Relatório de estágio supervisionado obrigatório em restaurante, com um diagnostico higiênico sanitário(2019) Lira, Vanessa Azevedo; Silveira, Ana Virgínia Marinho; Lira, Maria de Lourdes Azevedo; http://lattes.cnpq.br/8207812492517198; http://lattes.cnpq.br/6172165135794878
