DES MOINES, Iowa (AP) — A California law taking effect Jan. 1 could make pork harder to find and more expensive. Voters in 2018 overwhelmingly approved the law, which requires more space for breeding pigs, egg-laying chickens and veal calves. National veal and egg producers are optimistic they can meet the new standards, but only 4% of hog operations now comply with the new rules. Unless the courts intervene or the state temporarily allows non-compliant meat to be sold in the state, California will lose much of its pork supply. Groups have long been pushing for more humane treatment of farm animals but the California rules could be a rare case of consumers clearly paying a price for their beliefs.
