Study of Iran south coast shrimps for contamination with Vibrio spp. with focus on Vibrio cholerae (Summer and fall 2000)

With regard to the economic importance of shrimp export and report of cases of cholerae especially in south coasts of Iran, and because of the possibility of contamination of surface water which is used in farms with waste water. this study was conducted. In this study marine and farm shrimps from south coasts of Iran were evaluated for possible infection with Vibrio spp .specially Vibrio cholerae. In three stages, 770 samples of shrimps from marine and farms in provinces of Hormozgan , Boshehr and Khozestan were collected. After early preparation in the provincial food control laboratories the samples transferred to Tehran. Each sample included 25g shrimp in a strile ice-bag. Samples were tested for Vibrio spp. by enrichment and culture on selective media and biochemical tests. Although four spices of vibrio, which have little importance in food hygiene .including V.parahaemolyticus, V.damsella , V. alginolyticus and V.fluvialis were isolated from the samples ,no V.cholerae was found. Although it is now very unpredictable to find any contamination of shirimps with V.cholerae in south coasts of Iran, it is recommended to prevent contamination of surface water with sewage.
