While USDA considers the humane treatment of animals to be important, the USDA’s regulatory authority does not extend to animals used for food, fiber, or other agricultural purposes. However, most livestock production industries in the United States have developed and implemented science-based animal care guidelines. Assurances that animals are being raised according to these guidelines are provided through voluntary third-party audits rather than legislation.
Typically, State and local laws govern the treatment of farm animals. Accordingly, you may wish to contact the appropriate State and local authorities. Local and national humane organizations can also provide information on humane treatment of farm animals.
