Escherichia coli O157 isolates from bovine hide (n=117) and beef trimmings (n=32) from a single abattoir were examined by pulsed field gel electrophoresis (PFGE). Using BioNumerics software, dendrograms of isolates from each sample type (i.e. hide and beef trimming) were produced. In assessing the genetic relatedness of isolates, a similarity criterion of 80% was applied. The 117 E. coli O157 hide isolates were grouped into 14 clusters, comprising of 109 different PFGE profiles. Of the 109 different PFGE profiles, 8 were common to multiple isolates (i.e. shared 100% similarity by PFGE). The 32 E. coli O157 beef trimming isolates produced 28 different PFGE profiles and 2 clusters. Of the 28 PFGE profiles, 2 were common to multiple isolates and the remaining 26 were distinct. On a number of sampling occasions, isolates displaying identical PFGE patterns were recovered from multiple isolates collected from a single sample type (i.e. hides or trimmings), suggesting cross contamination from contaminated hides/animals to uncontaminated hides/animals and from contaminated beef trimmings to uncontaminated beef trimmings during abattoir operations.
