Results obtained by examination of cloacal swabs from poultry for the presence of verotoxigenic strains of E. coli O157:H7 are presented. Twenty samples (9.2%) of 216 samples examined were positive for E. coli O157. Out of 20 E. coli O157, 19 strains were positive for the production of both verotoxins (VT1 and VT2). However, none of them was positive for the presence of H7 antigen.
