Resumo: | The objective of the present study was to evaluate the influence of the environment upon marine shrimp farming with regard to bacteriological quality of the water, pond sediments and livestock (Litopenaeus vannamei). The study was carried out on four shrimp farms in Cearà (1, 2, 3 and 4). Of the eight samplings performed, 3 involved water (one outside the farm-PEX, one at the pumping site-PB, and one in the pond-PV); 3 involved sediment (at locations PEX, PB and PV), and two consisted of harvested and processed shrimp. Samplings were carried out in different seasons (dry, intermediary and rainy) and totaled 288 individual samples (108 water; 108 sediment; 72 shrimp). The most probable numbers (MPN) of total coliforms (TC), fecal coliforms (FC) and Escherichia coli were determined and samples were investigated for Salmonella strains. The bacteriological contamination observed on the shrimp farms was predominantly caused by TC and FC and was most intense during the intermediary season. Farms 2 and 4 yielded the highest concentrations of FC in water and sediment, respectively, at sampling locations PEX and PB during the three seasons. No shrimp sample presented E. coli values above those permitted by the European Commission (EU). However, on account of the Salmonella values observed, Farms 2 and 4 would be barred from exporting shrimp to the EU. In addition, water sampled at Farm 3 contained Salmonella strains capable of infecting the livestock. Only Farm 1 presented an exogenous and endogenous environment free of fecal contamination. The presence of Salmonella and E. coli in water and shrimp samples is disquieting, considering the fact that theses pathogens are of fecal origin and that their natural habitat is the intestinal tract of warm-blooded animals. |

O presente estudo teve por objetivo pesquisar a influÃncia do meio exÃgeno à carcinicultura na qualidade bacteriolÃgica da Ãgua, sedimento dos viveiros e no camarÃo de cultivo (Litopenaeus vannamei). Foram realizadas oito coletas em quatro Fazendas 1, 2, 3 e 4, sendo trÃs de Ãgua (ponto externo-PEX, ponto de bombeamento-PB e viveiro-PV) e trÃs de sedimento (PEX, PB e PV) e duas amostras de camarÃo (despescado e processado). As coletas foram realizadas em diferentes perÃodos sazonais (seco, intermediÃrio e chuvoso), perfazendo um total de 288 amostras, sendo 108 de Ãgua, 108 de sedimento e 72 de camarÃo. Foi determinado o NÃmero Mais ProvÃvel (NMP) de coliformes totais (CT), fecais (CF), e de Escherichia coli, alÃm da pesquisa e identificaÃÃo de Salmonella. Os resultados mostram que a contaminaÃÃo microbiolÃgica das fazendas à feita predominantemente por CT e CF, com maior intensidade na estaÃÃo intermediÃria. As Fazendas que apresentaram valores mais elevados de CF nas trÃs estaÃÃes foram as Fazendas 2 (PEX e PB) e 4 (PEX e PB) nas amostras de Ãgua e sedimento, respectivamente. Nenhuma amostra de camarÃo, das fazendas, apresentou valores acima do permitido para E. coli pela ComissÃo EuropÃia (CE). PorÃm se o parÃmetro considerado for a presenÃa de Salmonella, as Fazendas 4 e 2 nÃo estariam habilitadas a exportar os crustÃceos para paÃses da UniÃo da Comunidade EuropÃia. E ainda, das Ãguas da fazenda 3 tambÃm foram isoladas Salmonella o que facilmente poderia contaminar os camarÃes cultivados. Dentre as quatro fazendas, somente a Fazenda 1, nÃo apresentou ambiente endÃgeno e exÃgeno contaminado com material fecal. A detecÃÃo de Salmonella e a presenÃa de E. coli nas amostras de Ãgua e camarÃo à preocupante, uma vez que estes patÃgenos sÃo de origem fecal e seu habitat à o trato intestinal dos animais de sangue quente e pecilotÃrmicos.http://www.teses.ufc.br/tde_busca/arquivo.php?codArquivo=2889application/pdfinfo:eu-repo/semantics/openAccessporreponame:Biblioteca Digital de Teses e Dissertações da UFCinstname:Universidade Federal do Cearáinstacron:UFC2019-01-21T11:15:56Zmail@mail.com - |
