Here's one "health" food that is probably best left off your facility's menu in raw or cooked form. The Food and Drug Administration had previously warned that elderly people and those with weakened immune systems should not eat raw bean sprouts due to the risk of E. coli and salmonellosis. Now the agency has updated its advisory to include lightly cooked mung bean sprouts. "As stated in the 2002 Food Code, hospitals, day care centers, nursing homes and senior centers should not serve sprouts," according to an FDA statement.
