Listeria are Gram-positive, motile (at mesophilic condition), psychrotrophic bacteria with six (6) known species - L. monocytogenes, L. innocua, L. seeligeri, L welshimeri, L ivanovii, and L grayi. They are associated with clinical impor- tance due to their virulence activity. But among the six species of Listeria, the most prevalent is L. monocytogenes causing listeriosis including sepsis, men- ingitis, encephalitis, corneal ulcer, pneumonia, cervical infection, and abortion, where elderly, immunocompromised, pregnant women, and infants are the most susceptible. Due to the increasing Listeria outbreak, certain high-risk foods became necessary to test for Listeria contamination. These high-risk foods are as follows: ready-to-eat seafoods, pre-packed fruits and vegetables, drinks made from fresh fruits, deli meats without further cooking process, un- pasteurized milk, soft-serve ice cream, soft cheeses, salad dressings, and raw vegetable garnishes.
