Objective
The overall aim of this study is to assess the prevalence and persistence of STEC in sheep and in soil within small to medium-sized farm environments, so that farmers can address on-farm food safety issues involved with grazing production field. The objectives include: 1) To determine the baseline prevalence of STEC in sheep in bio-diversified California farms; 2) To assess the persistence and concentration of generic E. coli, total coliforms and STEC in the soil (from Day 0 to harvest); 3) To analyze factors that may affect E. coli persistence; 4) To identify good agricultural practices (GAP) that prevent cross-contamination.
