If you regularly buy frozen berries or vegetables from Costco's frozen food aisle, you should check the label and verify it's not in a group of products currently being recalled.
Canadian residents should toss out any Nature's Touch Organic Berry Blend products purchased between December 11, 2015, and April 15. Officials in Canada are investigating links between consumers contracting hepatitis A from the frozen fruit; 11 cases related to the recall were reported. Costco's other recall affects over 30 US states as well as Canada. Frozen food vendors Wellsley Farms Organic, True Goodness by Meijer, Organic by Nature, and Schwan's issued recalls on several products due to a potential listeria outbreak. If your freezer is stocked with sweet corn, green peas, or shelled edamame from one of these suppliers, you should dispose of the product.
