evidence: Federal, State, and local policies, such as tax incentives for donating food, can support food-loss reduction, recovery, and recycling, but some policies may fail to address the underlying causes of loss. Moreover, some existing policies may unintentionally serve as barriers, such as restrictions on gleaning (the harvest of intentionally unharvested produce for the purpose of donation) or supply control through private-public marketing orders. Quality standards enforced through private and public marketing orders may also affect food-loss rates.
