In 2006, Arizona passed a ballot measure that prohibited the use of gestation crates and veal crates by 2012. The law forbids confinement that prevents pigs and calves from lying down, fully extending their limbs, or turning around in a complete circle without touching the sides of their enclosure. Violation of this law is a class 1 misdemeanor, punishable by a jail term of up to 6 months, a maximum fine of $2500, or a maximum of 3 years probation. 

In 2022, Arizona issued regulations that phase out the use of cages in egg production, along with prohibiting the in-state sale of eggs from caged hens. 

After January 1, 2025, aside from certain exceptions, all eggs produced and sold in the state must come from hens housed in a cage-free manner. 

While producers are already prohibited from using gestation or veal crates in the state of Arizona, beginning in 2025, egg operators will need to keep their hens in cage-free housing systems that contain environmental enrichments including scratch areas, perches, nest boxes, and places to dust bathe. And eggs that are sold in the state will also need to be raised under these conditions.
