Food safety education from farm to end user is essential in the mitigation of food safety concerns associated with fresh produce. Iowa State University developed a multi-disciplinary three-level sequential program ("Know," "Show," "Go") to provide a holistic approach to food safety education. This program provides knowledge on GAP (Know); guides development and documentation of food safety practices (Show); and aids in grower's readiness for third party auditing (Go). Evaluations suggest this program is effective in changing long term food safety knowledge, attitude, and behaviors. The multi-disciplinary sequential approach can be used by other Extension programs to reach.
