Massachusetts Question 3: Pork Confinement, Certification, Penalties

Massachusetts Question 3 pork requirements prohibit the sale of uncooked whole pork cuts in the Commonwealth if they come from a breeding pig that was confined so tightly it could not lie down, stand up, fully extend its limbs, or turn around in a complete circle. The pork provisions took effect on August 24, 2023, and compliance runs through the supply chain by way of signed written certifications.¹ The Attorney General enforces the law, with civil fines of up to $1,000 per violation and the power to seek injunctions against non-compliant products.

What Counts as Covered Pork

The sales ban reaches “whole pork meat,” which the regulations define as any uncooked cut consisting entirely of pork aside from seasoning, curing agents, and similar additives. Chops, ribs, roasts, loins, ham, bacon, steaks, brisket, shanks, and cutlets all qualify.² If it looks like a recognizable raw cut on the butcher’s counter, assume it is covered.

Ground, diced, minced, or otherwise comminuted pork falls outside the rule, even when nothing else has been added. Sausage is not covered. Neither are processed and combination foods such as hot dogs, sandwiches, soups, or pizza with pork toppings, because those contain ingredients beyond pork meat and basic additives.²

The law applies only to sales that happen inside Massachusetts, with the sale location defined as the place where the buyer takes physical possession. Pork that passes through a Massachusetts distribution center on its way to a buyer in another state is not subject to the ban, because no in-state sale occurs.²

The Confinement Standard for Breeding Pigs

Massachusetts does not use a square-footage rule. The standard is behavioral: a breeding pig cannot be housed in a way that prevents it from lying down, standing up, fully extending its limbs without touching the enclosure’s sides, or turning around in a complete circle without obstruction.³ If the pig can do all four, the housing passes regardless of exact dimensions.

That distinction matters because California’s Proposition 12, which the Massachusetts rule is often confused with, sets a fixed 24-square-foot minimum per breeding pig. The two laws reach similar outcomes in practice but measure differently. Traditional gestation crates fail the Massachusetts test by a wide margin because the animal cannot turn around at all.

Certification Requirements Through the Supply Chain

Compliance moves down the chain through written certifications. Under 330 CMR 35.05, any business involved in selling whole pork meat in Massachusetts, whether located inside or outside the state, can certify that the product was not derived from a cruelly confined animal.⁴

A compliant written certification must contain:

The name and address of the entity producing, selling, or supplying the pork.
Identification of the covered animal raised or the product produced.
The date of the certification.
A statement, signed under penalty of perjury, that the pork was not derived from a breeding pig confined in a cruel manner.
Where applicable, the name of the entity the product was sold or supplied to, and the date of that transaction.

The signed-under-perjury element has real weight. A supplier who signs a false certification faces potential perjury consequences on top of any underlying violation of the confinement law.⁴

The 2021 amendments built in a protection for downstream buyers. A retailer or distributor that relies in good faith on a written certification from its supplier can use that reliance as a legal defense if enforcement comes knocking.⁵ The law does not require third-party audits; self-certification is permitted, though some businesses use outside auditors to verify that upstream facilities actually meet the behavioral standards.

Penalties and Who Enforces

The Massachusetts Attorney General has exclusive enforcement authority. Each violation carries a civil fine of up to $1,000 under M.G.L. c. 129 App., § 1-6. The Attorney General can also seek injunctive relief to stop the sale of non-compliant products, which is often the more consequential tool because it can shut down a product line rather than just impose a per-sale fine.

The Department of Agricultural Resources drafted the implementing regulations at 330 CMR 35.00 and provides compliance guidance. Businesses should expect that inspectors may examine certifications and procurement records for whole pork meat in inventory, and the state can trace documentation back through the supply chain to check that certifications are consistent.

For a business that unknowingly sells non-compliant pork, the good-faith defense is the whole ballgame. A valid supplier certification on file is the shield. A business that stocks whole pork cuts without any certification paperwork is exposed to both fines and injunctions with nothing to fall back on.

Court Challenges That Shaped the Current Rules

The pork industry challenged Massachusetts directly in Triumph Foods, LLC v. Campbell, arguing that Question 3 discriminated against out-of-state producers, was preempted by federal meat inspection law, and violated several constitutional provisions. In October 2025, the First Circuit Court of Appeals rejected every argument, holding that the law “does not discriminate against out-of-state producers in purpose or effect” and does not impose a substantial burden on interstate commerce.⁶

One piece of the original law did not survive the litigation. The district court severed the so-called slaughterhouse exemption, which would have let pork sold on the premises of a federally inspected facility in Massachusetts avoid the confinement requirements. The court found the exemption effectively favored in-state processors, since only a company with a federal facility inside the Commonwealth could use it. Neither side appealed the severance, so that carve-out is gone.⁶

The U.S. Supreme Court’s May 2023 decision in National Pork Producers Council v. Ross dealt with California’s Proposition 12, not Massachusetts, but the Court’s reasoning that states may regulate products sold within their borders based on animal welfare preferences significantly weakened the legal basis for Commerce Clause challenges to Question 3.⁷

Federal Preemption Risk Ahead

Congress remains the main threat to Question 3’s long-term survival. The Ending Agricultural Trade Suppression (EATS) Act would bar states from imposing standards on agricultural products that exceed federal requirements, which would effectively preempt both Question 3 and Proposition 12. The EATS Act was included in H.R. 7567, the Farm, Food, and National Security Act of 2026, which passed the U.S. House of Representatives on April 30, 2026, by a vote of 224 to 200.⁸

The bill still needs Senate approval and the President’s signature, and farm bills get heavily renegotiated between chambers. The preemption provision has drawn opposition from animal welfare organizations, state attorneys general, and some farming groups that have already invested in compliant housing. Until a final bill passes, Question 3 remains in force exactly as the First Circuit upheld it, and businesses selling whole pork into Massachusetts need their supplier certifications in order.
