Item Pesquisa de listeria monocytogenes em linguiças do tipo frescal(Universidade Federal de Goiás, 2014-02-25) Almeida, Thatyana Lacerda de; André, Maria Cláudia Dantas Porfirio Borges; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Borges, Liana Jayme; Rezende, Cintia Silva Minafra e; Campos, Maria Raquel HidalgoStudies conducted in Brazil showed the presence of pathogenic bacteria in foods whose consumption can cause diseases and food-borne disorders. In general, consumers have expectations about consuming safe food and foodborne diseases are highly unpleasant, generating distrust in the quality of food products on the market. Listeria monocytogenes is an important pathogen transmitted by food, whose accurate identification is important for the correct risk determination associated with the ingestion of various kinds of food. Considering the importance of this pathogen to the consumer, the present study aimed to isolate and identify Listeria monocytogenes in frescal type of sausages, butchers sold in the city of Aparecida de Goiânia Goiás. 88 samples were analyzed, been 44 frescal type of pork sausage and 44 of chicken meat from the butchers of Aparecida de Goiânia, registered in the Comércio Varejista de Carnes Frescas in Goiás. Was followed the methodology of sampling and analytical recommended by the American Public Health Association, and the analyzes were performed at the Laboratório de Controle Higiênico Sanitário de Alimentos da Faculdade de utrição da Universidade Federal de Goiás. Of the total samples, six were considered suspicious and inteneded with biochemical evidence, none were considered positive for the target bacteria. The results obtained in this research found a quality sausages for the target bacteria, but must be reinforced the need for legal support to facilitate recognition of research actions broader control and disease severity dissemination, especially in pregnant women, newborn born, immunocompromised and elderly who are the most vulnerable population.Item Isolamento e identificação de Campylobacter spp. em linguiças de frango frescal(Universidade Federal de Goiás, 2015-03-27) Rosa, Sarah Inês Rodrigues; Rezende, Cíntia Silva Minafra e; http://lattes.cnpq.br/5841210447886226; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Borges, Liana Jayme; André, Maria Cláudia Dantas Porfírio Borges; Campos , Maria Raquel HidalgoCampylobacteriosis have been related as main cause of gastroenteric diseases in Europe and North America. In Brazil, the lack of data about this disease hinders a comparison with other countries and difficult the decision making to combat the causative bacterium. Due high incidence of Campylobacter spp. in meat, main in poultry carcasses and by-products, this study aimed isolate and identify this bacteria in chicken fresh sausage sampled in Aparecida de Goiânia, in Goiás state. Thirty-four samples were collected in the period from July to October, each one were subdivided in 68 sub-samples, half of sub-samples were analyzed immediately, in fresh/chilled condition, and the other half were frozen for further analysis. In 11.65% of fresh samples were isolated Campylobacter coli and Campylobacter lari. For the frozen samples, no positive results were observed. Worked also with simple and double concentration of enrichment medium, recovering three positive samples in the simple one and a positive sample in the double. It was observed 100% resistance against the antimicrobial bases tested. It is recommended more studies of this nature, broadening the scope as to poultry products and greater number of samples; therefore, it is believed that they may evaluated the prevalence of this important microorganism in animal products in the Goiás state. Such investigations may provide important information for the National Program for Monitoring Prevalence and Bacterial Resistance in Chicken, established in 2008 by the National Agency of Sanitary Surveillance of the Ministry of Health.
