Brenham TX-based Blue Bell Creameries has issued a voluntary recall of certain flavors of ice cream distributed across the South after finding chocolate chip cookie dough from a third-party supplier for use as an ingredient was potentially contaminated with Listeria.

The company said it would recall pints and half-gallons of Blue Bell Chocolate Chip Cookie Dough and half-gallons of Blue Bell Cookie Two Step produced at its Sylacauga AL creamery. Internal testing discovered the cookie dough from Garner IA-based Aspen Hills Inc was potentially tainted, according to Blue Bell.

No illnesses have been reported from the ice cream, which was distributed in Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North and South Carolina, Tennessee, and Virginia.

This recall affects Chocolate Chip Cookie Dough half-gallons with the code date 082618226 on the carton bottoms and pints with the code dates 081518242 and 082418242, as well as Cookie Two Step half-gallons with the code dates 080418222 and 081818224. Consumers should return the affected cartons to their place of purchase to receive full refunds.

Listeria can induce serious, sometimes deadly infections in young children and frail or elderly people, as well as those with weakened immune systems. Healthy people may receive short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain, and diarrhea, but the infection can bring miscarriages and stillbirths to expectant mothers.

In 2015, Blue Bell stopped sales and issued a voluntarily recall of all of its products due to bacteria contamination that was linked to 10 Listeria cases in four states. Three people died from the infections.
