The most recent large scale incident was in Washington,Idaho,California,and Nevada in early 1993 where approximately 500 people suffered cases of hemorrhagic colitis associated with E. coli 0157:H7 and three children died from eating contaminated hamburgers served at a fast food restaurant chain (U.S. Department of Agriculture (USDA) 1993,Schneider 1993). Another significant incident was the 1985 Chicago outbreak of salmonellosis associated with tainted pasteurized milk (Ryan et al. 1987),while concerns mount about salmonella in chicken,Alar on apples.
