Alpine Slicing and Cheese Conversion Company in Wisconsin is voluntarily recalling “HEB Queso Cotija (Grated)”, “El Viajero Queso Quesadilla (Shredded)”, “El Viajero Queso Cotija (Grated)”, and “BMF Queso Quesadilla (Shredded)” because it has the potential to be contaminated with Listeria monocytogenes, 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 infection can cause miscarriages and stillbirths among pregnant women.
