A Michigan company is recalling its sunflower seeds and snack mixes made with the seeds because these products have the potential to be contaminated with Listeria.

Lipari Foods of Warren, MI — located north of Detroit — issued a voluntary recall of its Raw Sunflower Seeds, Roasted Sunflower Seeds and Snack Mixes Wednesday after sampling by the Michigan Department of Agriculture revealed the presence of Listeria monocytogenes in raw sunflower seeds sold at retailers.

Products subject to the recall include 52 items that were distributed between April 5 and June 11, 2013 to manufacturers and retailers in nine states in the Midwest and East, including Illinois, Indiana, Kentucky, Michigan, Ohio, Pennsylvania, Tennessee, West Virginia and Wisconsin.
