A coalition of animal protection agencies are currently working to get the world's strictest welfare law for farmed animals passed in California.
If implemented, Prevent Cruelty California's proposed law that would ban cages of any kind for hens, gestation crates (also known as sow stalls) for pigs, veal crates for calves.
This would result in higher welfare standards than across the EU. The law would have implications for local farmers, as well as out of state producers who wanted to do business in California.
The coalition is collecting signatures
Under the US ballot system - a form of direct democracy - organizations and individuals can put laws directly to a public vote - bypassing politicians - as long as they can acquire enough signatures.
The coalition, which is currently collecting signatures - includes welfare organizations The Humane Society of the United States, California veterinarians, Center for Food Safety, and family farmers.
Josh Balk, Vice President of Farm Animals Protection for the Humane Society of the United States [HSUS] called the proposed law 'history in the making'.
He added: "This is the greatest shot farm animals have ever had."
