Which regulatory entity enforces the Animal Welfare Act?

The entity responsible for enforcing the Animal Welfare Act is the USDA (United States Department of Agriculture), specifically through its Animal and Plant Health Inspection Service (APHIS), under the division known as Animal Care. This agency's role includes setting standards for animal care, conducting inspections of facilities that use animals, and ensuring compliance with welfare regulations.

The Animal Welfare Act establishes minimum standards for the humane care and treatment of certain animals. The USDA/APHIS/Animal Care is tasked with implementing these standards and ensuring that individuals and organizations comply with the regulations set forth in the Act.

Other organizations mentioned in the options, such as OHRP (Office for Human Research Protections), OMB (Office of Management and Budget), and OLAW (Office of Laboratory Animal Welfare), have distinct responsibilities that do not encompass the enforcement of the Animal Welfare Act. OHRP pertains to human subjects research regulations, OMB oversees budgetary and management issues in the federal government, and OLAW focuses on the policies regarding the health and welfare of laboratory animals but does not have the same regulatory enforcement authority as USDA/APHIS/Animal Care when it comes to the Animal Welfare Act.
