In this study, the prevalence of Vibrio cholerae, parahaemolyticus, mimicus, vulnificus and spp. in shrimp from retail markets Reynosa, Mexico was determined. A total 765 isolates, identified as (59·1%), V. cholerae (17·8%), mimicus (6·7%) parahaemolyticus (4·6%), were obtained; not detected. Most strains isolated supermarkets (48·1%), followed by street vendors (37·3%) stores (14·6%). Moreover, several virulence genes cholerae: toxR (100%), OmpU (76·5%), hlyA VPI (19·9%) tcpA (5·1%); mimicus: vmh wzb (74·5%), pilF (54·9%), (43·1%), (29·4%) tdh (9·8%); parahaemolyticus: tlh VP1680 (51·4%) (11·4%). These results show low safety food potential risk to consumers' health, since product Mexican cuisine is sometimes served raw or semi‐cooked. This study shows pathogenic that commercialized Reynosa city. could represent a outbreaks related contaminated with have been previously reported. Additionally, fishing has major role Mexico's economy.
