Good agricultural practices (GAP) are voluntary guidelines for produce farmers to reduce the risk of foodborne illnesses through safe and sustainable farming methods. The guidelines are based on the FDA's recommendations for minimizing microbial hazards in fresh produce. As more people consume fresh produce and foodborne illness outbreaks associated with produce have increased, some large buyers now require vendors to be audited by a third party to certify they follow GAPs. Modern agriculture focuses on conservation and renewability of resources like traditional agriculture extracts, in order to support overall economic development through effective population and environmental resource management.
