Sampling and Recall Activities
At the outset of the investigation, labels and production codes for possibly implicated products were not available from the consumers' homes to assist in confirming the source of the outbreak or in identifying product for recall.
The CFIA immediately developed and launched a national sampling plan for various frozen burgers, including The Gourmet Meat Shoppe Big & Juicy Burgers. A total of 151 retail boxes and 23 food service packages, representing 9 production dates, were sampled. On February 18, 2013, the CFIA laboratory identified 1 positive sample for E. coli O157:H7 in The Gourmet Meat Shoppe Big & Juicy Burgers produced on August 14, 2012.
Health Canada conducted a Health Risk Assessment of the affected product and determined that it posed a high health risk (Health Risk 1) to consumers. Recall actions were taken immediately.
On February 19, the CFIA in collaboration with Canada Safeway Ltd. issued a Health Hazard Alert for The Gourmet Meat Shoppe Big & Juicy Burgers and The Butcher's Cut beef patties, produced on the same line, with a best before date of August 14, 2013 Cardinal brand Beef Burgers, production code ending with 22712, also produced on the same line were recalled from the hotel, restaurant and institution level by Cardinal Meat Specialists Ltd.
Pulsed Field Gel Electrophoresis (PFGE) analysis (fingerprinting) was conducted on the positive sample of E. coli O157:H7. The result matched the illnesses reported on February 13, 2013 by PHAC.
Source of Contamination
The CFIA food safety investigation focussed on identifying the potential source of E. coli O157:H7 contamination.
