Vegetables and Juice
Raw vegetable sprouts are loaded with vitamins. But they often carry disease-causing bacteria such as salmonella and E. coli; seeds may become contaminated by animal manure, and hot and humid growing conditions allow bacteria to flourish. Sprouts -- including alfalfa, radish, and mung bean (Chinese sprouts) -- are often added to sandwiches and salads, so request that yours are prepared without.
Also, drink only pasteurized juice (packaged unpasteurized juice is identified on the label). Most of the time you don't need to worry about this: 98 percent of fruit and vegetable juices sold in supermarkets are pasteurized. But it becomes a bigger issue at restaurants, juice bars, and farm stands, where unpasteurized juices are commonly served.
In healthy adults, salmonella and E. coli infections cause diarrhea, nausea, abdominal cramping, and fever that last for several days. Pregnant women, however, can become seriously ill from these infections and can occasionally pass the infection to their fetus.
