California is set to enforce a 2018 proposal that requires more space for breeding pigs, laying hens, and calf calves, leading to a potential pork supply shortage. The new rules, which could result in a significant increase in pork costs, are causing concern for restaurants and grocers that rely heavily on pork. The swine industry is seeking federal assistance and has sued the state, but the courts have so far supported the California law. The Humane Society of the United States has advocated for the industry to comply with the laws, representing the will of the Californian public.
