Summary

Three hundred forty-seven samples obtained from 30 dairy processing plants were tested for the presence of Yersinia spp. Ten plants had one or more positive sites. A total of 20 of the 347 sites tested were positive for one or more species of Yersinia. Ten of the 20 positive samples were obtained from coolers and entrances to freezers. Yersinia-positive cooler/freezer sites were obtained from 9 of the 10 positive plants. The remaining 10 Yersinia-positive sites were from raw milk receiving areas (4/10) and drains around machinery (6/10), including an ice maker, a case washer, two holding tanks, one filler machine and a packaging area.
