Publix customers in Georgia are being urged to check their freezers after the grocery chain recalled a specific lot of frozen blueberries linked to 12 confirmed cases of E. coli illness.

The recall involves 10-ounce bags of GreenWise Organic IQF Blueberries with lot code 60401 and a best-by date of February 9, 2028. The product was sold at Publix stores in Georgia and seven other southeastern states. No other lot codes or best-by dates are included in the recall.

The recall was initiated after 12 people became ill with E. coli O145:H28 infections between May 11 and June 5. Consumers who have the affected blueberries should not eat them and should either throw them away or return them to Publix for a full refund.

Health officials say E. coli O145 can cause severe stomach cramps, diarrhea that may be bloody, and vomiting. Young children, older adults, and people with weakened immune systems are at the greatest risk for serious complications, including a type of kidney failure known as hemolytic uremic syndrome. Anyone who becomes ill after eating the recalled product should seek medical attention promptly.

The recalled blueberries were produced by Frutas y Hortalizas del Sur S.A. of Chile. The company and Publix are working with regulatory agencies as the investigation continues.
