Several grocery store chains are recalling ice cream bars that may be contaminated with Listeria. The bars were manufactured by Fieldbrook Foods Corporation between January 1 and December 31 of last year. The bars have sell by dates of January 1, 2018 through December 31, 2018. The company says routine testing found Listeria in a few ice cream bar samples. They say there is no evidence of contamination before October 31, but the company extended the recall back to January 1 as a precaution. No illnesses have been reported. Customers who have bought these ice cream bars are urged to return them to the place of purchase for a full refund. They were sold at various stores under various brand names. For example, ice cream bars sold at Kroger were under the Kroger Arctic Blasters brand name.
