USDA Animal and Plant Health Inspection Service (APHIS)

USDA Animal and Plant Health Inspection Service (APHIS)

The Animal and Plant Health Inspection Service is a multi-faceted Agency with a broad mission area that includes protecting and promoting U.S. agricultural health, regulating genetically engineered organisms, administering the Animal Welfare Act and carrying out wildlife damage management activities. These efforts support the overall mission of USDA, which is to protect and promote food, agriculture, natural resources and related issues.

To protect agricultural health, APHIS is on the job 24 hours a day, 7 days a week working to defend America’s animal and plant resources from agricultural pests and diseases. In the event that a pest or disease of concern is detected, APHIS implements emergency protocols and partners with affected States to quickly manage or eradicate the outbreak. This aggressive approach has enabled APHIS to successfully prevent and respond to potential pest and disease threats to U.S. agriculture.
