What is Listeria? Recent Spread Makes News

There was a recent outbreak of listeria in a particular brand of ice cream. But, what is listeria?

Listeria-tainted ice cream is linked to a total of five illnesses and three deaths in Texas and Kansas from the Blue Bell brand and Sabra recalled 30,000 cases of classic hummus, because of listeria-contamination concerns.
