Statistics reports of foodborne diseases are quite low in Brazil, however, this fact is a matter of Public Health. In their majority concerning consumption of bivalves meat, the availability of safe products requires the use of technology as food irradiation. The objective of this paper was to evaluate the presence of bacteria resulting from the environmental contamination and epidemiological importance, Salmonella spp., total and faecal coliforms of mussel （Perna perna） from that region and the use of irradiation on the product in natura. Fifteen indicative samples of mussel were collected from five gr owing points in Ilha Grande Bay. A sample of each point was irradiated with doses of 1.0 and 1.5 kGy. The bacteriological analysis followed the instructions of the Brazilian legislation. The samples presented irregularities in relation to Salmonella spp. and faecal coliforms, the latter for the control group. The control group was noticed as not appropriate for consumption. The dose of 1.0 kGy was effective for the reduction of faecal coliforms, but ineffective for the extinction of Salmonella spp.展开更多
