E. coli O157:H7 Linked to California Walnuts Being Investigated in Canada

walnuts.gifThe Public Health Agency of Canada (PHAC) is investigating an outbreak of E. coli O157:H7 in three provinces. The Canadian Food Inspection Agency (CFIA) and Amira Enterprises Inc. are warning the public not to consume certain bulk and prepackaged raw shelled walnut products described below because these products may be contaminated with E. coli O157:H7.

PHAC is working with Health Canada, the Canadian Food Inspection Agency (CFIA) and authorities in the affected provinces to actively investigate this outbreak. At this time, the outbreak investigation indicates that several individuals have reported consuming raw shelled walnuts.

Until further notice, consumers who have raw shelled walnuts in their home can reduce the risk of E. coli infection by roasting the walnuts prior to eating them. Consumers should place the nuts on a cooking sheet and bake at 350°F for 10 minutes, turning the nuts over once after five minutes.

Consumers should also be aware that the Canadian Food Inspection Agency (CFIA) has issued a Health Hazard Alert and is warning the public not to consume certain bulk and prepackaged raw shelled (out of the shell) walnut products because these products may be contaminated with E. coli.
