The US House of Representatives passed the Farm, Food, and National Security Act of 2026, which animal welfare organizations argue would override state animal welfare laws enacted by voters in multiple states. The bill's most controversial provision would nullify animal confinement laws in at least 15 states, including California's Proposition 12, which sets minimum space standards for breeding pigs and was upheld by the US Supreme Court in 2023.

Humane World for Animals and its affiliate Humane World Action Fund opposed the bill, which also blocked measures to improve oversight of commercial dog breeding facilities, enforcement of the Animal Welfare Act, restrictions on horse slaughter, taxpayer support for the mink industry, and retirement pathways for research animals. The Senate is expected to face opposition to these provisions as advocates push for a Farm Bill that respects state-level animal welfare standards and rejects attempts to strip states of their power to protect animals.
