This label can be found on: Beef, mutton (sheep), goat, bison and dairy products.

ORGANIZATION: There is no single program or government agency behind the “grass fed” label.

Labels on meat with a “grass fed” claim have to be approved by the Food Safety and Inspection Service (FSIS), an agency of the U.S. Department of Agriculture (USDA). FSIS staff reviews a one-time application with supporting documentation supplied by the company making the claim.

Labels on dairy products are regulated by the Food and Drug Administration (FDA), which does not require prior approval or verification of a “grass fed” labeling claim. The FDA requires that labels on dairy products are truthful and not misleading but does not have a regulatory definition for the “grass fed” labeling claim.

What this label means

Beef and dairy cattle are ruminants, and their digestive systems have evolved to digest high-fiber and low-starch grasses. They gain weight more rapidly when they are fed grain in addition to grass, which has become standard practice in the beef and dairy industries. Grain-feeding comes at a cost to the nutritional value of the meat and dairy they produce, and the animals’ health.

Meat: The US Department of Agriculture (USDA) requires prior review and approval of labels on meat products making a “grass fed” claim. The agency requires that “grass fed” or “100% grass fed” claims may only be applied to meat and meat product labels derived from cattle that were only (100%) fed grass (forage) after being weaned from their mother’s milk. The diet must be derived solely from forage, and animals cannot be fed grain or grain by-products and must have continuous access to pasture during the growing season until slaughter.

Dairy: The Food and Drug Administration (FDA) oversees labels on dairy products, and has no regulatory definition of “grass fed” and no guidelines for producers making a “grass fed” claim. The FDA requires that labels on dairy be truthful and not misleading. Currently, the FDA has no position on whether the claim would be truthful and not misleading if dairy cows were allowed to graze on pasture and also fed grain in the diet. No verification is required for dairy producers making a “grass fed” labeling claim.

Why it matters

Nutritional benefits. Studies suggest that there are important health benefits from consuming 100% grass fed meat and dairy compared with grain fed meat and dairy. Studies have found that, compared to grain fed alternatives, grass fed meat contains lower levels of overall fat and higher levels of vitamins and antioxidants; grass fed meat and dairy have also been found to have higher levels of omega-3 fatty acids, which appear to provide health benefits.

Animal health benefits. Ruminants on a grass-based diet without grain are less likely to suffer from gastrointestinal disorders such as acidosis. With acute acidosis, the acidity level and glucose levels in the animal’s intestines increase markedly due to grain consumption, leading to damage to the intestinal wall or other health conditions.

Another health effect of a high-grain diet for cattle is a higher rate of liver abscesses. For prevention of liver abscesses in grain fed cattle, the FDA has approved numerous antibiotics that can be added to cattle feed – the same grain-based feed that is often contributing to the abscesses in the first place. Antibiotics approved for this purpose include the critically important antibiotics tylosin, ceftiofur, virginiamycin and chlortetracycline. A sustainable way to prevent liver abscesses is to promote healthy animals with a species-appropriate diet of grass and forage.

How meaningful is this label?

“Grass fed” is a meaningful claim. On its own on a label, the claim is somewhat meaningful on meat, but not meaningful on dairy products.

On meat labels, producers can make a “grass fed” claim after submitting a one-time label application with the USDA, with required documentation to support that the “grass fed” claim means the animals were not given any grain. However, there is no requirement for on-farm inspections and no requirement for annual review or auditing of the producer’s records to ensure compliance.

On dairy products, the “grass fed” claim is not verified and the FDA has no regulatory definition, so the label is not meaningful on its own. The FDA requires that labels on dairy be truthful and not misleading. Currently, the FDA has no position on whether the claim would be truthful and not misleading if dairy cows were allowed to graze on pasture and also fed grain in the diet. Some companies making a “grass fed” labeling claim on dairy products feed grain in addition to grass.

Consumers looking for 100% grass fed meat and dairy products should look for one of the meaningful labels listed below accompanying a “grass fed” claim.

Consumers should look for the following additional labels or seals, which are highly meaningful:

PCO Certified 100% Grassfed
American Grassfed
Certified Grassfed by AGW
NOFA-NY Certified 100% Grass Fed


The following additional seals and labels mean that the grass fed claim has been verified:

USDA Process Verified
