Grass Fed Beef, Grass Finished & Pasture Raised: What’s the Difference?
Updated: Oct 12
How to Decode Beef Labels:
When you’re looking at a grocery store meat case, packages of beef can carry so many different phrases: Grass Fed, Grass Finished, Pasture Raised, Organic, Natural. Which of these actually tells you how the cattle were raised? At Eat Pasture Raised, we help you find products from animals actually raised outdoors, in conditions that match the marketing.
Beef labeling is primarily overseen by USDA’s Food Safety and Inspection Service. Some terms describe the animal’s diet, some describe where it lived, and others describe how the meat was processed. We’ll help you understand which terms are meaningful and which aren’t, so you can better understand the origins of the food you’re buying.
Here’s how to decode the labels on beef at your local grocery store.
Grass Fed / 100% Grass Fed Beef
Overview: “Grass Fed” tells you what the animal ate — but in the case of beef, it also tells you quite a bit about how the animal lived. The USDA considers “Grass Fed,” “Grassfed,” “Grass-Fed,” and “100% Grass-Fed” to all mean the same thing for beef: after weaning, cattle must eat only grass and other forage, cannot be fed grain or grain by-products, and must have continuous access to pasture during the growing season. The USDA specifically notes that this means 100% grass-fed cattle can never be confined to a feedlot.
What this tells you: “100% Grass Fed” is one of the most meaningful labels you can look for on beef. It tells you the cattle ate a forage-based diet, after weaning, throughout their lives and had continuous access to pasture during the growing season until slaughter. For Eat Pasture Raised, Grass Fed beef meets our standard for cattle raised outdoors.
Grass Finished Beef
Overview: While they sound similar, and can often be found on the same label, “Grass Finished” on its own does not mean the same thing as “Grass Fed.” Under USDA guidance, “Grass Fed” cattle must have continuous access to pasture during the growing season. A “Grass Finished” claim does not carry that same requirement. “Finishing” means the final period of a cattle’s life before slaughter, when they are raised to their final market weight. “Grass Finished” describes how cattle were fed during the finishing stage of their lives (i.e. they were fed grass, not grain), but on its own does not tell you that they spent the majority of their lives outside on pasture. A grass-finished cow could still have spent much of its life in a feedlot.
What this tells you: “Grass Finished” alone is not a reliable signal that cattle were raised on pasture. If you’re looking for beef from cattle that spent meaningful time living on pasture, look for “Grass Fed,” “100% Grass Fed,” or “Pasture Raised” claims instead.
Pasture Raised Beef
Overview: The USDA’s current animal-raising guidance strongly encourages producers using claims like Pasture Raised and Pasture Fed to document that cattle were raised on pasture (which they define as land predominantly covered in rooted vegetation) for the majority of their lives. Pasture Raised describes where the animal lived, not necessarily an exclusively grass-and-forage diet. Pasture-raised cattle could potentially receive supplemental grain, but it does signal that the animal lived outside.
To look for additional verification of pasture-based living and animal-welfare standards, you may also see certifications such as Certified Animal Welfare Approved by AGW®, Certified Humane®, or G.A.P.® Step 4 and above. These programs have their own requirements and auditing, but a third-party certification is not necessary for us to consider a USDA-substantiated claim meaningful.
What this tells you: If you’re looking to buy products from cattle raised outside, pasture-raised beef meets that standard. If you’re looking to buy products from cattle raised outside and fed only grass, we recommend opting for the “Grass Fed” or “100% Grass Fed” label.
Organic Beef
Overview: The USDA requires organic cattle to have access to the outdoors year-round and to graze on pasture throughout the regional grazing season, which must be at least 120 days per year. During that season, they must get at least 30% of their diet from pasture. These are meaningful pasture requirements, but the Organic standard does not require cattle to spend the majority of their lives on pasture.
What this tells you: Organic tells you that cattle had real access to pasture and spent part of each year grazing, but it is not as strong a signal of a pasture-based life as Grass Fed or Pasture Raised. If your priority is beef from cattle that spent the majority of their lives outdoors on pasture, look for “Grass Fed,” “100% Grass Fed,” or “Pasture Raised.”
Natural Beef
Overview: “Natural” sounds like it might describe how cattle were raised, but it doesn’t. Under USDA rules, Natural refers to the meat itself: it means the product contains no artificial ingredients or added color and is only minimally processed. The claim says nothing about whether cattle had access to pasture, were grass fed, or were raised outdoors.
What this tells you: Natural tells you about how the meat was processed, not how the animal lived. Natural beef can come from cattle that were raised in a feedlot or fed grain. If you want beef from cattle raised outdoors, look for “100% Grass Fed” or Pasture Raised instead.
Other Common Beef Claims
Overview: Beef packaging is full of claims that can sound like they describe how cattle was raised, but many of them actually tell you something completely different.
No Antibiotics Ever / Raised Without Antibiotics. These claims relate to antibiotic use, not housing. Cattle raised without antibiotics can still be raised or finished in a feedlot.
No Added Hormones. Unlike poultry, hormones can legally be used in beef production, so this is a meaningful distinction about how cattle were raised. But it does not tell you whether cattle had access to pasture or lived outdoors.
Grain Fed / Corn Fed. These claims describe what cattle ate, not where they lived. Grain-fed cattle may have spent time on pasture earlier in their lives, but the claim does not guarantee pasture access.
Regenerative / Regeneratively Raised. These terms generally relate to farming and land-management practices, but on their own they do not guarantee a particular amount of time on pasture or a specific animal-welfare standard.
Humanely Raised / Responsibly Raised. These phrases can sound reassuring, but unless they are reinforced with specific words or standards that require outdoor access (see above!), they do not necessarily tell you whether cattle were raised outside.
Angus. Angus refers to a breed of cattle, not how the animal was raised. Angus beef can be grass fed, grain fed, pasture raised, or feedlot finished.
USDA Prime / Choice / Select. These are beef quality grades based on characteristics of the meat, including marbling. They do not tell you whether cattle were raised outdoors or had access to pasture.
What this tells you: These claims may provide useful information about other aspects of a beef product, but none of them on their own tells you that the cow was raised outside. We recommend looking for “100% Grass Fed” or Pasture Raised on the package.
