According to a posting on Food Safety Canada’s website:

Romaine lettuce imported from the United States (U.S.) have been associated with several outbreaks of foodborne E. coliO157:H7 illnesses in Canada and the U.S. Food safety investigations from U.S. authorities have identified a recurring geographical area as the source of the outbreaks. This area encompasses the California Salinas Valley counties of Santa Cruz, Santa Clara, San Benito, and Monterey.

To decrease the risk associated with E. coli O157:H7 in romaine lettuce, the Canadian Food Inspection Agency (CFIA) is implementing temporary Safe Food for Canadians (SFC) licence conditions for the importation of romaine lettuce originating from the U.S. Between September 28 and December 22, 2022, importers of romaine lettuce and/or salad mixes containing romaine lettuce from the U.S. must:

  • declare that the product does not originate from counties of Santa Cruz, Santa Clara, San Benito and Monterey in the Salinas Valley, California, U.S., or 
  • submit an attestation form and Certificates of Analysis for each shipment to demonstrate that the romaine lettuce does not contain detectable levels of E. coli O157:H7

The complete details on the temporary SFC licence conditions and other existing import requirements are outlined in this document.

The temporary SFC licence conditions are in addition to other existing import requirements.
