Egg labels explained

Egg cartons carry two different kinds of claims: food-safety and quality statements that are mandatory or federally graded, and housing and welfare claims whose meaning depends on who verifies them. This page sorts out which is which.

Who regulates what

Several agencies share responsibility for shell eggs, according to the USDA Food Safety and Inspection Service (FSIS):

FDA enforces the Egg Safety Rule (21 CFR part 118), which applies to producers with 3,000 or more laying hens whose eggs are not treated, such as by pasteurization, and requires preventive measures against Salmonella Enteritidis on the farm plus refrigeration in storage and transport (FDA).
USDA FSIS verifies that shell eggs packed for consumers are labeled “Keep Refrigerated” and are stored and transported under refrigeration.
USDA AMS runs the Shell Egg Surveillance Program and the voluntary grading program — the source of the USDA grade shield and of verified housing claims on graded cartons (AMS).
State agriculture departments enforce state housing and sales laws (see state cage-free laws).

Housing and welfare claims

Label	Who defines it	What it requires	Source
Cage-free	USDA AMS (on USDA grade-shield cartons); several state laws	Hens can roam vertically and horizontally in indoor houses, with fresh food and water, litter, perches, nests and scratch areas. No outdoor access required.	AMS QAD 709 memo
Free-range	USDA AMS (on grade-shield cartons)	Everything required for cage-free, plus “continuous access to outdoors during their laying cycle.” The outdoor area may be fenced or covered with netting.	AMS QAD 709 memo
Pasture-raised / pastured	No single federal definition; AMS requires third-party certification on grade-shield cartons	Must be “currently certified by a nationally recognized certifying body such as American Humane or Certified Humane.”	AMS QAD 709 memo
Certified Humane “Free Range”	Humane Farm Animal Care (private certifier)	2 sq ft of outdoor space per bird; outdoors at least 6 hours a day, weather permitting.	The Poultry Site, 2014
Certified Humane “Pasture Raised”	Humane Farm Animal Care (private certifier)	108 sq ft per bird (1,000 birds per 2.5 acres); outdoors year-round with housing for nighttime protection.	The Poultry Site, 2014
USDA Organic	USDA National Organic Program	Under the Organic Livestock and Poultry Standards, poultry must have year-round outdoor access; porches do not count as outdoor space.	AMS OLPS fact sheet
“No hormones”	USDA FSIS (labeling of poultry)	Hormones are not allowed in raising poultry; a “no hormones added” claim must be followed by “Federal regulations prohibit the use of hormones.”	FSIS labeling terms
USDA grade shield (AA, A)	USDA AMS (voluntary, paid grading)	A licensed USDA grader checked quality and weight. Grading is voluntary; inspection for wholesomeness is mandatory.	FSIS

Cage-free vs free-range vs pasture-raised

The key legal difference between USDA-verified cage-free and free-range is outdoor access: the AMS memo requires free-range hens to have continuous access to the outdoors during the laying cycle, while cage-free hens are housed indoors, often in multi-tier aviaries (AMS). For pasture-raised there is no single federal definition, so AMS relies on third-party certifiers. One such certifier, Humane Farm Animal Care, set 108 square feet per bird for its “Pasture Raised” standard, compared with 2 square feet for its “Free Range” standard (The Poultry Site).

These AMS definitions apply to claims on cartons packed under USDA grading. According to AMS, cartons without the grade shield are not subject to its facility, sanitation and labeling requirements (AMS).

Organic

The USDA’s Organic Livestock and Poultry Standards (OLPS) rule, published in November 2023, requires organic poultry to have year-round outdoor access and bars porches from counting as outdoor space (AMS fact sheet). Operations had to comply by January 2, 2025, but layer operations certified before that date have until January 2, 2029 to meet the outdoor stocking-density and soil and vegetation requirements (Federal Register).

Outdoor access and food safety

Outdoor access brings its own safety rules. In August 2022 the FDA issued guidance for producers whose hens can go onto porches, outdoor runs or pasture, treating a porch as an area outside the poultry house and suggesting measures such as monitoring outdoor areas for rodents and flies (FDA).

Safety and date statements

Safe Handling Instructions. Untreated shell eggs must carry the statement “SAFE HANDLING INSTRUCTIONS: To prevent illness from bacteria: keep eggs refrigerated, cook eggs until yolks are firm, and cook foods containing eggs thoroughly.” Retailers must hold eggs at 45°F (7.2°C) or cooler. Eggs treated to kill Salmonella, such as in-shell pasteurized eggs, are exempt (FDA).
Dates. On USDA-graded eggs, code dates are optional. “Sell by” or “EXP” dates can be no more than 30 days from packing; “use by” or “best before” dates may not exceed 45 days including the pack date (FSIS).

Labels that say little about housing

“Natural” is defined by FSIS as a product with no artificial ingredient or added color that is only minimally processed — a definition that says nothing about how hens are kept (FSIS). FSIS also notes that artificial color additives are not permitted in eggs (FSIS).
