Final answer:
The IACUC and legislation like the AWA and the PHS Policy guide the U.S. in animal-cruelty legislation issues, with advocacy organizations like PETA bringing visibility to these matters.
Step-by-step explanation:
The organization that advises the United States on proposed animal-cruelty legislation includes the Institutional Animal Care and Use Committee (IACUC), which reviews proposals for research involving non-human animals. The Animal Welfare Act (AWA) and the Public Health Service Policy on Humane Care and Use of Laboratory Animals (PHS Policy) serve as primary regulations in the United States pertaining to biomedical research animals. The AWA, amended several times since 1966, requires researchers to register their use of animals and consider alternatives to procedures causing distress or pain. Meanwhile, the PHS Policy mandates that institutions conducting federally funded animal research must have an IACUC, including a veterinarian and a community member, to ensure humane treatment of animals in research.
Additionally, organizations like People for the Ethical Treatment of Animals (PETA) often serve as policy advocates drawing public attention to issues of animal cruelty and influencing legislation and regulation.
