California’s egg law requires that every shell egg and liquid egg product sold in the state come from hens housed in cage-free systems meeting specific space and enrichment standards, that every business handling those eggs register with the state, and that sellers keep records proving their supply chain complies. The rules apply to California farms and to out-of-state producers shipping in, and violations carry both criminal fines and civil penalties.
What the Housing Standards Require
Since January 1, 2022, hens whose eggs are sold in California must be kept in cage-free housing. Cages of any kind are prohibited. Each hen must have at least 144 square inches of usable floorspace, and the housing system must meet the space and enrichment standards in the 2017 United Egg Producers’ cage-free guidelines, which call for roughly one to one and a half square feet per hen depending on the system.1California Legislative Information. California Health and Safety Code 25991
A qualifying cage-free system can be a multi-tiered aviary, a partially slatted system, or a single-level litter floor system. Whatever the design, hens must be able to roam unrestricted and have access to scratch areas, perches, nest boxes, and dust bathing areas.1California Legislative Information. California Health and Safety Code 25991 Housing a hen with less space, or in any kind of cage, is defined as “confined in a cruel manner” under state law. That definition is what triggers both the criminal penalty and the ban on selling the eggs in California.2California Legislative Information. California Health and Safety Code 25990
The standards apply equally to in-state and out-of-state producers. Where the hens live doesn’t change the rule; what matters is whether the eggs end up on a California shelf.
Who Must Register
Every business that handles, distributes, or sells eggs in California must register with the California Department of Food and Agriculture’s Egg Safety and Quality Management (ESQM) program. There are no exemptions. Out-of-state handlers shipping eggs into California register the same way California handlers do.3California Department of Food and Agriculture. Egg Safety and Quality Management Program
Registration itself is cheap. The fee is $15 for out-of-state handlers. The ongoing cost is an assessment of up to five cents per 30-dozen case of eggs sold, which funds the inspections and audits the ESQM program runs. Two narrow exemptions apply to the assessment: eggs sold directly to household consumers from flocks of 500 hens or fewer, and shipments to federal government agencies accompanied by a USDA grade certificate.4California Department of Food and Agriculture.

ESQM auditors conduct shell egg food safety audits at laying facilities, compliance inspections at production and wholesale operations, and inspections at packing, distribution, and retail locations. That authority extends to out-of-state facilities whose eggs enter California.3California Department of Food and Agriculture. Egg Safety and Quality Management Program
Sales and Labeling Rules
You cannot sell shell eggs or liquid eggs in California if you know or should know the eggs came from hens confined below the housing standards. That duty falls on retailers, wholesalers, and distributors as well as producers. In practice it means sourcing only from registered, compliant suppliers and keeping documentation that shows it.5California Legislative Information. California Code HSC – Shelled Eggs
Egg cartons must display the producer or distributor’s name and address. Labels using terms like “cage-free” or “pasture-raised” must match California’s legal definitions. Mislabeling can be pursued under the state’s unfair competition statute and carries civil penalties of up to $2,500 per violation.
Pasteurized in-shell eggs carry an added rule. Each consumer-facing container must show a “Sell by” date, and that date cannot be more than 75 days after pasteurization. The processor has to back the date up with a documented shelf stability study addressing public health criteria. If the eggs are later repacked, the original sell-by date carries over.6California Legislative Information. California Food and Agricultural Code 27644.5
Records You Have to Keep
Egg handlers must retain records of all egg transactions for three years. Records identifying the original plant where eggs were first processed must be kept for at least one year from the processing date. Every record, invoice, and document relating to eggs produced, stored, sold, labeled, or transported for sale in California is open to inspection and audit by the CDFA or its certifying agents.7Legal Information Institute.

How the Rules Reach Out-of-State Producers
If your hens aren’t housed in a compliant cage-free system, you cannot legally sell those eggs in California. The housing standard travels with the egg, not with the farm’s zip code.
The compliance path for an out-of-state operation starts with ESQM registration. Registration alone satisfies the legal requirement to sell in the state, but CDFA retains authority to run food safety audits and compliance inspections at out-of-state facilities. Many producers also obtain third-party cage-free certifications as added proof. Retailers that buy from a noncompliant supplier risk having products pulled from shelves and face enforcement of their own.3California Department of Food and Agriculture. Egg Safety and Quality Management Program
Penalties for Violations
The CDFA and local district attorneys enforce the law. Consequences come on two tracks.
On the criminal side, violating the farm animal cruelty provisions is a misdemeanor punishable by a fine of up to $1,000, up to 180 days in county jail, or both.8California Legislative Information. California Health and Safety Code 25993 The $1,000 cap applies per violation, and each noncompliant sale or each day of noncompliant confinement can be charged as a separate offense, so exposure for a commercial operation adds up quickly.
On the civil side, a violation of the sales ban is treated as unfair competition under Business and Professions Code Section 17200. That carries civil penalties of up to $2,500 per violation, injunctions ordering a business to stop selling noncompliant eggs, and court-ordered disgorgement of profits from the illegal sales. The California Attorney General, local district attorneys, and certain city attorneys all have standing to bring these actions. Courts weigh the seriousness of the misconduct, the number of violations, and how long they continued when setting the amount.9California Legislative Information. California Business and Professions Code 17200-17210
Is the Law Still Subject to Legal Challenge?
The core framework is settled. On May 11, 2023, the U.S. Supreme Court decided National Pork Producers Council v. Ross, which involved Proposition 12’s pork provisions but turned on legal reasoning that applies directly to the egg rules. The industry argued the law discriminated against interstate commerce, unconstitutionally regulated activity outside California, and imposed burdens on interstate commerce that were clearly excessive compared to its local benefits. The Court rejected all three arguments. Writing for the majority, Justice Gorsuch noted that the law imposes identical requirements on in-state and out-of-state producers, so it doesn’t discriminate, and the Court found nothing in its precedents supporting an almost-automatic rule against state laws that affect commerce beyond state borders.10Supreme Court of the United States. National Pork Producers Council v. Ross, No. 21-468
A separate theory, that the federal Egg Products Inspection Act preempts California’s sales ban and labeling rules, was pressed in a lawsuit brought by the Trump administration’s Department of Justice and dismissed by a federal court. Future administrations could try similar arguments, but courts so far have sided with California’s authority to set its own standards for products sold within the state.
