An outbreak of Salmonella Chester, an unusual strain of Salmonella, was identified in British Columbia, Alberta, Saskatchewan, and Ontario, Canada. The only common food consumed by the case-patients was headcheese, which had been purchased from various delicatessens from mid to late June. Headcheese is a deli product made from meat from the head of a pig, combined with gelatine and spices. Approximately half of the case-patients required hospitalization; most case-patients were over the age of 70. The product was manufactured for Freybe by Brandt Meat Packers, in Mississauga, Ontario, by Brandt Meat Products Ltd. The product was then distributed to the Overwaitea Food Group (which includes Save-on-Foods, PriceSmart Foods, Urban Fare and Cooper’s Foods) and Thrifty Foods stores, as well as other smaller delis in Western Canada and the Yukon. Because the headcheese was sliced and packaged at deli counters in various stores, most consumers may not be aware of the brand of head cheese purchased. The inspection of G. Brandt Meat Products also detected Listeria contamination. Although no cases were known to have developed listeriosis from the meat products, the various additional meat products were recalled and the production plant underwent a thorough cleaning.
