WEST DES MOINES, Iowa — Hy-Vee Inc. based in West Des Moines, Iowa, is voluntarily recalling one of its salad toppings and additional trail mix products across its eight-state region due to possible contamination with Listeria monocytogenes.

The products include Hy-Vee Garden Style Salad Topping, Hy-Vee Trail Mix Bars, Hy-Vee Peanut Almond Dark Chocolate Protein Bars, Hy-Vee Caramel Cashew Honey Crunch Trail Mix, Hy-Vee Dark Chocolate Cranberry Trail Mix, Hy-Vee Raisin and Nut Trail Mix, and Hy-Vee Santa Fe Trail Mix.

The potential for contamination was discovered after Hy-Vee’s sunflower kernel supplier, SunOpta, announced it was recalling specific lots of sunflower kernels due to the potential for Listeria monocytogenes. The initial recall was limited to sunflower kernel products produced at SunOpta’s Crookston, Minnesota, facility; however, this week, the recall was expanded even further to include additional products supplied to Hy-Vee and other retailers across the United States.

Listeria monocytogenes is an organism, which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria monocytogenes infection can cause miscarriages and stillbirths among pregnant women.

To date, no illnesses have been reported in connection with these products.
