A voluntary recall has been issued for a Vancouver Island-produced cheese linked to an E. coli outbreak that infected five people.

Little Qualicum Cheeseworks’ Qualicum Spice cheese should be discarded or returned to the place of purchase, according to the BC Centre for Disease Control.

The E. coli outbreak occurred between August and October and was traced back to the unpasteurized product, which has a best before date up to and including April 24, 2019.

An investigation is ongoing “to determine the source and extent of contamination,” the BCCDC said.
