Published in 2004 by Iowa State University Extension, On Farm Food Safety: Guide to Good Agriculture Practices (GAPs) looks at developing a safety plan through organizing action steps in line with Good Agricultural Practices (GAPs) to reduce the risk of foodborne illnesses on farms. These action steps focus on four primary components of production and processing: soil, water, hands, and surfaces. This publication also includes a list of further resources at the end.
