Consumption of food contaminated with Listeria monocytogenes can cause listeriosis, an uncommon but potentially serious disease. The most common manifestation of listeriosis is meningitis, which has symptoms of high fever, severe headache, neck stiffness and nausea. Listeriosis can also cause miscarriages and stillbirths, as well as serious and sometimes fatal infections to infants, the elderly and those with weakened immune systems such as persons with chronic diseases or taking chemotherapy for cancer. Below is a nice photo is a distinct umbrella shape on the motility tube which is produced by L.monoctogenes they are also small gram positive rods, and are beta hemolytic on sheeps blood agar.
