Aims: To study the incidence of Shiga‐toxigenic Escherichia coli (STEC) in seafoods from India. Methods and Results:Escherichia coli isolated from various seafoods such as fresh fish, clams and water were screened for the presence of stx , hly A and rfb O157 genes by PCR; 5% of clams and 3% of fresh fish samples were positive for non‐O157 STEC. Conclusions: STEC is prevalent in seafoods in India, and non‐O157 serotype is more common. Significance and Impact of the Study: Seafood could be a vehicle for transmission of STEC even in tropical countries.
