Proposition 12 ("Prop 12") was a California ballot proposition in that state's general election on November 6, 2018. The measure was self-titled the Prevention of Cruelty to Farm Animals Act. The measure passed, by a vote of about 63% Yes to 37% No. The proposition establishes new minimum requirements on farmers to provide more space for egg-laying hens, breeding pigs, and calves raised for veal. California businesses will be banned from selling eggs or uncooked pork or veal that came from animals housed in ways that did not meet these requirements.
