General Mills is voluntarily recalling four flavors of Nature Valley Protein Chewy Bars and Nature Valley Simple Nut Bars because the items may be contaminated with Listeria, a bacteria that can result in serious or life-threatening illness in consumers.

The issue is related to a nationwide recall by sunflower kernel supplier SunOpta. General Mills said no illnesses have been reported and the recall affects four flavors of Nature Valley's nearly 40 different products.

"We know this is inconvenient for consumers who love these four flavors," said Anton Vincent, president of General Mills Snacks Division. "We promise they will return as soon as it is safe to do so."

The recalled product list includes:

Nature Valley Protein Chewy Bar - Honey, Peanut & Almond with Pumpkin Seeds - 5 count.

Nature Valley Protein Chewy Bar-Peanut, Almond & Dark Chocolate - 5 count.

Nature Valley Simple Nut Bar - Roasted Peanut & Honey - 4 count.

Nature Valley Simple Nut Bar - Roasted Peanut & Honey - 16 count.

Nature Valley Simple Nut Bar - Almond, Cashew & Sea Salt - 4 count.

Nature Valley Simple Nut Bar-Almond, Cashew & Sea Salt - 25 count.
