Abstract: The rectal contents of 330 cull cows and 66 lambs were sampled over the 1984-1985 killing season at a New Zealand freezing works for the presence of Yersinia species. Samples from the cows revealed one isolation of Y. pseudotuberculosis and one isolation of Y. intermedia. Samples from the lambs gave thirteen isolates of Y. enterocoliticu, three of Y. inter-media, two of Y. pseudotuberculosis and one of Y. frederiksenii. Two of the isolates of Y. enterocolitica were shown to be serotype 0:3. Although no parallel studies were carried out on young cattle or adult sheep, these findings are consistent with the hypothesis that Yersinia infection primarily involves young animals. Thus there exists the potential for transmission of the above species of Yersinia from young animals to man which needs further detailed study.
