Abstract

Fresh and frozen seafood products (fish, shellfish, crustaceans, molluscs) in wide use in Croatia and typical for the Mediterranean diet, were examined for presence of microbiological contamination through winter and summer seasons. Total bacterial counts of aerobic mesophilic bacteria (AB), aerobic psychrophilic bacteria (AP), Salmonella spp., Enterobacteriaceae, Escherichia coli, Staphylococcus aureus, sulphite-reducing clostridia (SRC), Listeria monocytogenes, Vibrio cholerae and V. parahaemolyticus tests were performed. The microbiological quality of individual samples varied widely between the animal species and within winter/summer seasons regarding total counts of aerobic mesophilic and psychrophilic bacteria. The poorest quality was for (both summer and winter) fish samples, where 66.6 % of fresh and frozen fish were found unacceptable by Croatian standards. The overall prevalence of V. parahaemolyticus was 5 %. Its recovery rate was higher in fresh/frozen shellfish in both seasons than in other specimens or other storage/season conditions. Fresh crustaceans sampled in winter demonstrated significantly higher aerobic mesophilic counts than frozen ones. Unacceptable Enterobacteriaceae levels were obtained in 40 % of the summer fresh fish samples. The results of this survey constitute an indicator of bacteriological contamination of a variety of seafood. The findings could serve as a basis for future testing of seafood, and possibly as a template for developing a regional/Mediterranean testing scheme on the microbial contamination of seafood in order to establish data with comparative epidemiological and statistical values.
