WEST DES MOINES, Iowa (AP) — Hy-Vee Inc. says it is recalling a host of products because they contain peanut butter that has the potential to be contaminated with salmonella.

The company said in a news release on Saturday that it is recalling Peanut Butter Cookies, Monster Cookies, Peanut Butter Reeses Pieces Cookies, Peanut Butter Chocolate Chip Cookies, Lunchbox Reeses Pieces Cookies, Lunchbox Peanut Butter Cookies, People Chow Party Mix and Assorted Truffle Fudge.

The company said that all sell-by dates are included in this recall and that the items should be destroyed or returned to Hy-Vee for a full refund.

Hy-Vee officials say they ordered the voluntary recall after Peanut Corporation of America, a company that supplies bulk peanut butter to Hy-Vee, issued a recall of the peanut butter ingredient used to make the Hy-Vee bakery products.

The company said it was taking a “precautionary step.”

Salmonella can cause serious and sometimes fatal infections in young children, frail or elderly people. Healthy people who are infected often experience fever, diarrhea , nausea, vomiting and abdominal pain.

The recall applies to the items Hy-Vee stores in Iowa, Illinois, Missouri, Kansas, Nebraska, South Dakota and Minnesota.

The PCA recalled a number of lots of the product after health inspectors found salmonella contamination in an already-opened container of peanut butter at a nursing home in Minnesota. Hy-Vee had been shipped product from two of the lots.

The grocery chain said it has sent samples of the peanut butter to an independent lab for testing.

Hy-Vee, Inc., is based in West Des Moines. It operates 225 retail stores in seven Midwestern states.
