CDC study: Hummus tops the list of foods that sickened people

You might eat hummus because it's healthy and tasty, but the Mediterranean treat topped the list of foods that made people sick in a single outbreak, according to a just-released study of outbreaks of food poisoning that sickened people.

The U.S. Centers for Disease Control and Prevention studied 2007 data and reviewed a total of 1,097 food borne disease outbreaks that led to 21,244 illnesses and 18 deaths. Salmonella and norovirus were the top contaminants.

Salmonella was the cause of illness in two of the three largest outbreaks that year. Hummus was the top source with 802 illnesses, the CDC reported. Another Salmonella outbreak was linked to frozen pot pies that sickened 401 people. The second biggest outbreak was connected to 526 cases of norovirus at a conference hotel.
