The Canadian Food Inspection Agency says “there is no indication” the blueberries and mixed berries in a major U.S. recall over the risk of serious illness and potential death were distributed in Canada.

The U.S. Food and Drug Administration upgraded a recall of frozen blueberries and mixed berries sold at Publix grocery stores across the country to a Class 1 recall, the highest health risk level on Tuesday, citing E. coli contamination. Publix initially recalled the affected products on July 29.

The CFIA told Global News in a statement that it is “aware of the outbreak investigation of E. coli Frozen Blueberries in the United States (U.S.),” and “based on the information currently available, there is no indication that the products affected by this recall were distributed in Canada.”
