Fish and shrimp are very good sources of nutrients such as omega-3 fatty acids, vitamin D, and protein, so they form an important part of people's diet; However, seafood can bring risks for consumers, so the purpose of this study is to investigate the prevalence of Vibrio types in fish and shrimps caught in Qeshm city, Iran. In this study, 250 samples, 50 of each sample, including salted fish, Halvasfid, milkfish, shoe fish, and shrimp, were randomly taken from the beach of Qeshm City and transferred to the food hygiene laboratory of Shahrekord Azad University. The samples were tested according to the standard method of searching for Vibrio species. SPSS version 23 statistical software and chi-square statistical test were used for data analysis. The limit of significance in this study was considered (P<0.05). The results showed that the highest level of contamination among Vibrio was related to parahaemolyticus with 74% of contamination and the lowest level of contamination was related to alginolyticus with 14% of contamination. The contamination rate of salted fish, Halvasfid, milkfish, shoe fish, and shrimp were 30, 16, 6, 24, and 23% respectively. In this study, the risk of consuming raw, half-cooked, or undercooked products is clear. Therefore, it is important to pay attention to the hygiene principles after catching, i.e., freezing until the time of consumption and adequate cooking of the product.
