Plant Protection and Quarantine (PPQ) is one of six operational program units within the Animal and Plant Health Inspection Service (APHIS) of the United States Department of Agriculture (USDA). The PPQ works to safeguard agriculture and natural resources in the U.S. against the entry, establishment, and spread of animal and plant pests, and noxious weeds in order to help ensure the protection of native flora and an abundant, high-quality, and varied food supply.
