Kashi is recalling two varieties of its granola bars over concerns about possible contamination from listeria bacteria.

Kashi Trail Mix Chewy Granola Bars and Bear Naked Soft Baked Granola, Cinnamon + Sunflower Butter are both being recalled because of "possible serious and sometimes fatal infections" contamination from listeria monocytogenes.

"Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women," the company said in a statement. No other Kashi or Bear Naked products are affected.
