If today is an average day in the United States, 13 people will die from food poisoning. Another 200,000 will get sick for a few days. And several thousand more may begin to suffer reactive arthritis, paralysis, or other symptoms that can last for months or years (see "Food Poisoning's Long Shadow," May 2002, p. 1).
Which foods cause the outbreaks that sicken the most people? "Fruits and vegetables top the list," says Caroline Smith DeWaal, director of food safety at the Center for Science in the Public Interest (which publishes Nutrition Action Healthletter).
CSPI has just issued the fifth edition of Outbreak Alert, a tally of food poisoning outbreaks in the U.S. since 1990 in which the food sources have been identified. (The Centers for Disease Control and Prevention--CDC--declares an outbreak when at least two people who eat the same contaminated food get sick. Since 1990, 2,472 outbreaks have sickened 90,355 people.)
"About half of the fruit-and-vegetable outbreaks were caused by salads, berries, raw sprouts, and lettuce," notes DeWaal. "Four out of every ten produce outbreaks were the result of bacteria, viruses, and other pathogens that are commonly found in meat and poultry," she adds. That means that the fruits and vegetables were probably contaminated in the fields with tainted water or manure.
