More than 400 frozen food products have been recalled in North America amid fears of listeria-linked illnesses. The products are marketed under more than 40 brand names at major retailers, including Costco in Canada. Some of the products were sold as far back as 2014. So far, eight people have been sickened by listeria that’s genetically similar to that found in CRF vegetables, and two have died, though listeria was not the primary cause of death. The CRF plant closed two weeks ago. The company is still trying to pinpoint the source of the contamination.Click here for a list of the recalled products.
