Abstract

The impetus for considering pre-harvest efforts for shiga-toxigenic E. coli 0157 (sometimes termed E. coli O157:H7, and denoted in the remainder of this paper as simply 0157) has been the growing recognition that the risk of foodborne disease associated with 0157 cannot be eliminated at processing, retailing, or consumer levels. This has led to the multiple hurdles model (Figure 1) in which some reduction is made at each level. Since reductions are multiplicative, the overall effect is one of great reduction in risk.
