It said that pork sold in the state needs to come from pigs whose mothers were raised with at least 24 square feet of space, including the ability to lie down and turn around.
That rules out the confined "gestation crates," metal enclosures that are common in the pork industry.Two industry groups, the Iowa-based National Pork Producers Council and the American Farm Bureau Federation, sued over the proposition.
They say that while Californians consume 13% of the pork eaten in the United States, nearly 100% of it comes from hogs raised outside the state, primarily where the industry is concentrated in the Midwest and North Carolina.
