Abstract :
Today, consumption of seafood has a special place among consumers. Consumption of seafood can lead to the transmission of bacterial pathogens of primary or secondary origin, among the most important of these bacteria are Vibrio species that are naturally found in aquatic environments and in the bodies of aquatic organisms. Every year, many cases of food poisoning caused by Vibrio species are reported in consumed fish. The purpose of this research is to investigate the level of Vibrio contamination of raw fish sold in Shahrekord city. In this research, 50 fish samples were prepared from 30 fish and aquatic supply stores in Shahrekord city and then analyzed at the Nutrition and Organic Products Research Center of Islamic Azad University, Shahrekord branch. Vibrio parahaemolyticus, Vibrio cholerae, Vibrio vulnificus, Vibrio mimicus and Vibrio alginolyticus can be mentioned among the most important species investigated. Then, based on the presence or absence of grown spores, 40% of the meat of the studied samples (20 pieces) were infected with Vibrio. The high abundance of Vibrio species in the samples confirms the lack of hygiene in the fish and its products preparation and distribution centers. It seems that the processing stations and the method of transporting and distributing fish do not have proper hygiene.
