Labor Day—and its many barbecues—is a bad time to find E. Coli in your burger, but that’s what happened in Florida over the weekend. Publix Super Markets had to issue a ground beef recall, according to the Florida grocery chain and the U.S. Department of Agriculture (USDA). The voluntary recall is for ground chuck items purchased by consumers between June 25 and July 31, 2018. These items are believed to contain E. coli 026, a strain of e. coli that can make individuals sick within two to eight days of consumption.

This is a Class 1 recall, which the USDA defines as “a health hazard situation where there is a reasonable probability that the use of the product will cause serious, adverse health consequences or death.” The amount of meat being recalled has not been determined, nor has the source of the meat sold at Publix Supermarkets. Products being recalled include ground beef, burgers, and meatballs. A comprehensive list of the ground beef and other meat products being recalled can be found here.
