Abstract
The microbiological quality of fresh shrimp (Litopenaeus vannamei) commercialized in Fortaleza (CE) was investigated by quantifying the coagulase-positive staphylococci (CP Sph), total coliform (TC) and thermotolerant coliform (TTC). Besides, detection of Salmonella and Escherichia coli isolation techniques were carried out. Twenty-four samples purchased at retail were analyzed. Four (16.7%) samples showed CP Sph counts above of 103/g. No Salmonella was isolated from the analyzed samples. The rates of positive samples for TC, TTC and E. coli were 95.8%, 54.2% and 25.0%, respectively. According to the Brazilian legislation in force, those four Sph CP-positive samples with counts >103/g should be considered unsuitable for human consumption. The other fact that called attention was the E. coli isolation from 25% of analyzed samples, which is an indicative of fecal contamination.
