Resumo
Amostras de músculo de carpa comum (Cyprinus carpio) e de água de três viveiros fertilizados com dejetos de suínos e de um viveiro em que os peixes foram alimentados com ração comercial para peixes foram analisadas durante seis meses. O objetivo foi observar a presença de bactérias patogênicas, como Salmonella, Staphylococcus aureus e coliformes totais e fecais, em peixes comercializados in natura no município de Chapecó, Santa Catarina. Foram aferidos quinzenalmente, na água dos quatro viveiros, oxigênio dissolvido, pH, turbidez, alcalinidade total, dureza total, amônia, nitrato e ortofosfato, bem como a quantidade de coliformes totais e fecais. A análise microbiológica músculo dos peixes demonstrou ausência de Salmonella em todas as amostras. A contagem dos demais microrganismos manteve-se inferior ao limite máximo permitido pela legislação vigente, em todas as amostras. Portanto, os peixes analisados estavam aptos ao consumo humano, pois atenderam aos padrões recomendados pela Divisão Nacional de Vigilância Sanitária de Alimentos (DINAL). A comparação entre os viveiros fertilizados com dejetos de suínos e o viveiro fertilizado com ração comercial para peixes não apresentou diferença significativa, porém apresentou efeito significativo sobre oxigênio dissolvido, turbidez, alcalinidade total e amônia. A matéria orgânica foi responsável pelos maiores valores, com exceção da turbidez, que foi menor no viveiro fertilizado com ração comercial para peixes. Entretanto, após análise de todos os parâmetros físico-químicos e microbiológicos da água dos viveiros, pode-se constatar que todos os viveiros se enquadraram nas classes II ou III da classificação de águas interiores estabelecida pelo CONAMA.
Samples from common carp (Cyprinus carpio) muscle and water from three fish ponds fertilized with pig manure and one where the fishes were fed with commercial ration, were analyzed for a period of six months. The objective was to observe the incidence of pathogenic bacterial, such as Salmonella, Staphylococcus aureus, total and fecal coliforms, in fish sold in natura in Chapecó county, Santa Catarina. Dissolved oxygen, pH, turbidity, total alkalinity, total hardness, ammonia, nitrate and orthophosphate, total and fecal coliforms were monitored at each 15 days in the water from the four fish ponds. Bacteriological examination fulfilled in all samples from fish muscles evidenced absence of Salmonella in all samples. Others microorganisms count maintened in all samples lower than the maximum limit number admitted by present legislation. The fishes analised were suitable for human consumption, because they attend the standard recommendation by the National Division of Food Sanitary Vigilance (DINAL). Comparation between fish ponds fertilized with pig manure and fish pond fertilized with commercial ration for fish showed no significant difference for the variables: dissolved oxygen, turbidity, total alkalinity, and ammonia. The organic matter was responsible by the high values, excepted for turbidity, that was lower for the fish pond fertilized with commercial ration for fish. However, after all physical-chemical and micobiological analyses of water of the fish ponds, it was conclude that all fish ponds were classified in the II or III class of the inner water classification stated by CONAMA.
