In 2007, Oregon passed legislation phasing out the use of gestation crates over the following five years. Today, confining a pregnant pig for more than 12 hours during any 24-hour period in a manner that prevents the pig from lying down and fully extending her limbs or turning around freely is prohibited. Turning around freely means having the ability to turn in a complete circle in an enclosure without an impediment, including a tether, and without touching any side of the enclosure. A violation of this law is a Class A violation, resulting in a fine of $440. 

In 2019, Oregon passed legislation that prohibits the use of battery cages, and the in-state sale of eggs from hens raised in battery cages. This legislation took effect on January 1, 2024. Violation of this law may result in fees of up to $2,500.
