WEST DES MOINES, Iowa – Hy-Vee is recalling packages of its Spring Pasta Salad because of possible Salmonella contamination.

This voluntary recall covers both one pound and three pound containers produced between June 1 and July 13. The grocery chain says it has been notified of about 20 illnesses in Iowa, Minnesota, South Dakota, and Nebraska that could have been caused by the salad.

Hy-Vee says this product was distributed to all 244 of its stores in eight states, including Illinois, Missouri, Kansas, and Wisconsin, and had expiration dates ranging from June 22 to August 3. The company says it removed all Pasta Salad products affected by this recall from its shelves and service cases Monday night.

Anyone who bought Hy-Vee Pasta Salad in either of these sizes may return it to their local store for a full refund. For more information, contact Hy-Vee Customer Care Representatives at 1-800-772-4098.

The Centers for Disease Control and Prevention says Salmonella is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Symptoms include fever, possibly bloody diarrhea, nausea, vomiting and abdominal pain. Salmonella infection can also, in rare circumstances, produce more severe illnesses such as infected aneurysms, endocarditis and arthritis.
