Readywise’s serving bucket is a product containing prepared packages of shelf-stable food with a shelf life of 25 years, and is advertised as emergency supplies. The company said the recall was based on potential listeria contamination by one of its suppliers.

“In an abundance of caution, Red’s has expanded its voluntary recall on Southwestern Grilled Chicken Mini Burritos due to the potential of Listeria contamination in the chicken provided by one of our suppliers,” its notice said. The company also said customers should not eat it, but rather return it to Costco for a full refund.
