Grocery stores in the midwest are pulling pasta salad off their shelves in the most recent Salmonella outbreak.

On July 17, Hy-Vee, Inc. announced a voluntary recall of its Spring Pasta Salad due to a threat that it may be contaminated with Salmonella, as noted on the U.S. Food and Drug Administration website.

In what folks across the country might typically serve at a barbecue or summer party, the pasta salad has already been linked to 20 illnesses across Minnesota, South Dakota, Nebraska and Iowa.

The voluntary recall affects 1 pound (16 oz.) and 3 pound (48 oz.) plastic containers produced between June 1, 2018 and July 13, 2018. The product is typically available from the deli section of grocery stores and has an expiration date of June 22, 2018 and August 3, 2018.

Hy-Vee Pasta Salad comes in both 16 and 48 oz. containers

According to the U.S. Centers for Disease Control and Prevention, Salmonella is an organism that can cause severe and sometimes fatal infections in those with weakened immune systems, young children, or elderly persons.

Healthy individuals can experience diarrhea, fever, nausea, vomiting and abdominal pain. However, Salmonella can enter the bloodstream and cause even worse illnesses like endocarditis, arthritis, or arterial infection.

Hy-Vee recalled the product from 244 grocery stores in Iowa, Illinois, Missouri, Kansas, Nebraska, South Dakota, Minnesota and Wisconsin

Those who purchased the Hy-Vee Spring Pasta Salad should return it for a full refund. If you feel you have become sick from eating the contaminated salad, contact your physician.
