The CFIA has closed its current line of investigation. At this time, no further activity is anticipated.

The investigation began on February 13, 2013 and CFIA investigators pursued all avenues of inquiry, including:

  • Assessing production, inspection and testing records;
  • Reviewing plant food safety procedures; and
  • Conducting additional testing on burger ingredients.

The CFIA trace back investigation focused on the company's records to identify ingredients used in the production of the recalled burgers. As a result, the CFIA has confirmed that all available ingredients tested negative for the presence of E. coli which included: spices and some domestic beef ingredients. No inventoried imported ingredients remained for testing. As well, no contamination source was identified during the trace back investigation.
