A survey for Listeria species, motile aeromonads and Yersinia enterocolitica on bovine and ovine carcasses.
One hundred ovine and 100 bovine carcasses in two abattoirs were sampled just after dressing for the presence of Yersinia enterocolitica, Listeria monocytogenes and motile aeromonads. Yersinia enterocolitica was not isolated and only two samples were positive for Listeria spp. In both cases, the Listeria species were not normally pathogenic to man. In contrast, motile aeromonads were isolated from 81% of ovine and 35% of bovine carcasses.
