Listeria is a bacteria found in unpasteurized milk, smoked fish, soft cheeses (made with unpasteurized milk), raw meat, deli meats, hot dogs or sausages that are not fully heated (even pre-cooked ones), and unwashed vegetables.

Listeria can make humans very ill with Listeriosis if consumed though slight exposure to Listeria does not, in most cases, result in symptoms. A Listeria infection may present with fever, a sore neck and vomiting or diarrhea. Complicated forms can lead to the development of both encephalitis and certain forms of meningitis.

Those with weakened immune systems like small children, pregnant or nursing mothers, and the elderly are at greater risk and should exercise greater care.  A Listeria outbreak in Cantaloupes killed 33 people in 2011.
