Abstract

Clostridium difficile was isolated from 12 (20%) of 60 retail ground meat samples purchased over a 10-month period in 2005 in Canada. Eleven isolates were toxigenic, and 8 (67%) were classified as toxinotype III. The human health implications of this finding are unclear, but with the virulence of toxinotype III strains further studies are required.

Comparison of PCR ribotypes of Clostridium difficile isolates from meat and of human, bovine, and canine origin in Ontario, Canada, 2005, by using the method of Bidet et al (10). PCR 077, 014, and 027 represent international ribotype nomenclature recently reported for calves (4). PCR M26 and M31 are temporary ribotype designations. Note that PCR M31 and 027, both NAP1/toxinotype III ribotypes, are different.
