[The occurrence of Enterobacteria in marine shrimp farming systems in the coast of Piaui, Brazil.] Ocorrencia de enterobacterias em sistemas de carcinicultura marinha do litoral do Piaui, Brasil.

E-mail: rodrigocalvet@hotmail.com The objective this work we evaluated the sanitary-hygienic conditions of the production system used in different farms of shrimp culture from the coast Piaui. The identification of Salmonella spp., the enumeration of coliforms at 37o C and Escherichia coli in water samples, shrimp and ration, were evaluated. The results for coliform at 37oC and E. coli in the water samples of different stages of cultivation were similar regardless the location of sampling. Salmonella spp. was isolated in two water and shrimp samples from the farm “B”. These results indicated that this production system lead to presence of pathogenic enterobacterias. Coliforms nor Salmonella spp. were not detected in the ration samples. The amount of coliform at 35oC and at 45oC demonstrated that the nurseries are in good sanitary-hygienic conditions. The productive management used by the operators shrimp of Piaui is similar in all stages of cultivating and the environment are contaminated with coliform and E. coli in shrimps and water. The management system used in the shrimp culture favors the presence of Salmonella sp. in shrimps and waters of the nurseries, but does not favor the increasing of coliform and E. coli in the effluent. The ration used in crops are not a source of contamination of nurseries by coliform and E. coli.
