Penn State Extension conducted on-farm food safety workshops statewide to train fruit and vegetable growers on Good Agricultural Practices (GAPs). These workshops were evaluated using pre- and post-tests to assess the impact of the training on participating growers. Results indicate overall increases in produce growers' knowledge, attitudes, confidence, and intentions on GAP-related activities. However, few respondents (20%) intended to seek third-party certification (TPC) for their farms. Future evaluations should collect information on the challenges that growers face in implementing GAPs on their farms. Extension should tailor its food safety programs to meet growers' GAPs needs.
