Avaliação microbiológica da água e do camurupim (Megalops atlanticus) na Lagoa do Araçá, Recife, PE, Brasil

Abstract

The fish are important protein sources for feeding human being, however they can be vehicles of diverse pathogenic microrganisms for the public health. When it has pollution, the environment in which these animals are inserted if it becomes a way of bacteriological contamination, influencing in microbiota of the fish. Soon, if it makes not only necessary to monitor the quality of the food, but also to follow the water of where it was removed. The Lagoon of the Araçá, situated in Recife-PE, is inserted in a Unit of Conservation of the Nature, however, the great amount of and effluent domestic and industrials who receive daily has caused increasing alteration and degradation in the local ecosystem. Ahead to this problematic one, the present study it had as objective to evaluate the microbiological quality of the water and the Megalops atlanticus in the Lagoon of the Araçá. In the period of October of 2017 the June of 2018, water collections had been carried through for microbiological analyses. The samples of fish had been acquired from local fishing in the period of August of 2017 the June of 2018, for determination of the centesimal composition; of the percentage of eatable parts after-processing and microbiological evaluation using as indicating total and thermotolerant coliforms, Staphyloccocus aureus, Salmonella sp., Pseudomonas spp. e Clostrídio reducing sulfite 46ºC (Clostridium perfringens). The gotten results disclose high concentrations of total and thermotolerant coliforms in the water of the Lagoon of the Araçá, being above of the standards established in the Resolution nº 357/2005 of the CONAMA. The results found in relation to the fish are in compliance with the RDC nº 12/2001 of the ANVISA, but we do not have to discard the risk how much to the consumption due to the joined concentrations of bacteria of fecal origin, that confirm the contamination in the estuary for pathogen proceeding from the oustings of effluent. In accordance with the results of the centesimal composition, were observed that the Megalops atlanticus is a lean fish with raised protein text, and that its initial weight influences the incomes of filet, not eatable head and residues. These data assist how much to the information of this fish in the Lagoon of the Araçá and alert how much to the risk in the consumption for the population. In front of this, is recommendable that the governmental bodies search to consider action for the improvement of the sanitary conditions of the Lagoon of the Araçá, especially the adequate treatment of the domestic sewers that affect directly in the dynamics of this ecosystem.
