from cnn/money: Leafy greens - including lettuce and spinach - top the list of the 10 riskiest foods, according to a study from a nutrition advocacy group released Tuesday. The Center for Science in the Public Interest listed the following foods, in descending order, as the most risky in terms of outbreaks: leafy greens, eggs, tuna, oysters, potatoes, cheese, ice cream, tomatoes, sprouts and berries. The scientists rated these foods, all of them regulated by the Food and Drug Administration, by the number of outbreaks associated with them since 1990, and also provided the number of recorded illnesses. The severity of the illnesses ranged from minor stomach aches to death, the center said. With leafy greens such as lettuce, the top cause of illness were pathogens like E. coli, Norovirus and Salmonella in foods that were not properly washed.
