USDA Prime sounds like the ultimate stamp of approval on a steak. But here's something a lot of shoppers don't realize: Prime beef can come from cattle raised with approved hormones or antibiotics. The grade doesn't tell you whether the animal was grass-fed, pasture-raised or how it was treated. So what DOES Prime actually tell you?
Wait.
USDA Prime beef can come from cattle raised with hormones?
Yes.
That surprised us too.
USDA allows certain hormone implants to be used in beef cattle to promote growth. Antibiotics can also be administered to prevent or treat disease, subject to federal requirements including withdrawal periods before slaughter.
And none of that automatically prevents the beef from receiving a USDA Prime grade.
Why?
Because that's not what Prime measures.
A Prime grade does not tell you whether the animal received added hormones.
It does not tell you whether antibiotics were used.
It does not tell you whether the animal was grass-fed.
It does not tell you whether it spent its life on pasture.
It does not tell you how the animal was handled.
And it does not tell you which ranch raised it.
Those are separate questions.
So what exactly are USDA graders looking at when they put that familiar Prime, Choice or Select shield on beef?
Let's take a look.
PRIME IS A GRADE OF THE BEEF, NOT THE LIFE OF THE ANIMAL
This distinction changes the way you look at that little shield.
USDA's beef quality grades evaluate characteristics of the carcass.
For the familiar Prime, Choice and Select grades, one of the biggest factors is marbling, those little flecks of fat distributed throughout the muscle.
USDA describes Prime as having at least slightly abundant marbling, Choice as having at least a small amount, and Select as having at least a slight amount, subject to the applicable maturity standards.
That's useful information.
Marbling can contribute to moisture, tenderness and flavor.
But here's the important distinction:
The grader is evaluating the beef in front of them.
They're not grading the pasture the animal lived on.
They're not grading the handling it received.
They're not grading its diet as a grass-fed claim.
They're not grading whether hormones or antibiotics were used.
USDA has entirely different labeling requirements for some of those claims.
SO YES, A PRIME STEAK CAN COME FROM CATTLE GIVEN APPROVED HORMONES
USDA is very straightforward about this.
Certain hormones are approved for use in beef cattle to promote efficient growth. USDA lists both naturally occurring and synthetic hormonal compounds that may be used as implants.
USDA also explains that the claim “no hormones administered” may be approved on beef labeling when the producer provides sufficient documentation demonstrating that hormones were not used in raising the animals.
Think about what that tells us.
If Prime already meant no hormones were used, there wouldn't need to be a separate substantiated claim telling consumers that.
They're two different pieces of information.
Prime = carcass quality grade.
No hormones administered = animal-raising claim requiring its own support.
A package can tell you one without telling you the other.
THE SAME GOES FOR ANTIBIOTICS
USDA says antibiotics may be administered to cattle to prevent or treat disease. Federal withdrawal periods are required before slaughter so drug residues can clear according to applicable requirements. FSIS also conducts residue testing.
But again:
Prime doesn't answer the antibiotic question.
USDA treats “no antibiotics added” as a separate labeling claim. To use it, the producer must provide documentation demonstrating that the animals were raised without antibiotics.
So you could theoretically have two beautiful Prime steaks sitting next to each other.
Both could meet the USDA requirements for Prime.
Yet the animals behind those steaks could have been raised very differently.
The shield alone wouldn't tell you that.
AND PRIME DOESN'T MEAN GRASS-FED OR PASTURE-RAISED EITHER
This may be another surprise.
A USDA Prime shield isn't a certification of an animal's entire feeding or production system.
USDA itself describes Prime beef as coming from young, well-fed beef cattle and emphasizes its higher level of marbling.
The quality grade isn't designed to answer:
Was the animal grass-fed?
Did it live on pasture?
How much space did it have?
Where did its feed come from?
How far did it travel?
How was it handled?
Those characteristics may matter tremendously to the person buying the beef.
They're simply outside what the Prime shield is telling you.
THEN WHAT DOES A USDA GRADER ACTUALLY LOOK AT?
Now the grading system starts to make a lot more sense.
USDA has two different systems for grading beef carcasses:
Quality Grade
and
Yield Grade.
Quality grading gives us the familiar:
Prime
Choice
Select
along with Standard, Commercial, Utility, Cutter and Canner.
Yield grading asks a different question:
How much usable lean meat is the carcass expected to produce?
Yield Grades run from 1 through 5, with Yield Grade 1 representing a higher expected yield of closely trimmed, boneless retail cuts than Yield Grade 5.
And to determine all of this, one particular part of the animal becomes incredibly important.
THEY LOOK AT THE RIBEYE
Yep.
The ribeye.
When a beef carcass is evaluated, characteristics visible in the exposed ribeye muscle provide important information for grading.
For quality grading, one of the biggest things graders evaluate is:
Marbling.
And USDA doesn't simply categorize it as:
Lots.
Some.
Not much.
There are established degrees of marbling.
Prime, Choice and Select correspond to different minimum marbling requirements, together with the applicable maturity and quality characteristics.
For younger carcasses, for example:
Prime: minimum Slightly Abundant marbling
Choice: minimum Small marbling
Select: minimum Slight marbling
So when you see that Prime shield, this is much closer to what it's actually communicating.
THE GRADER ALSO LOOKS FOR CLUES ABOUT MATURITY
The animal doesn't arrive with its birthday attached to the ribeye.
Instead, USDA standards use physical characteristics of the carcass to evaluate maturity.
That can include characteristics of the bones and cartilage, ossification, ribs and characteristics visible in the ribeye muscle itself.
Those maturity characteristics work together with marbling and other quality factors to determine the appropriate quality grade.
So there's legitimate science and standardization behind the shield.
Prime isn't meaningless.
Quite the opposite.
It just means something much more specific than many shoppers may assume.
AND THEN THERE'S YIELD GRADE
This is an entirely different measurement.
To determine Yield Grade, USDA looks at four major factors:
Fat thickness over the ribeye
Ribeye area
Hot carcass weight
Kidney, pelvic and heart fat
Together, those characteristics help estimate how much closely trimmed, boneless retail product the carcass will yield.
So the ribeye is doing double duty.
Its marbling helps tell graders about quality.
Its size helps tell them something about carcass yield.
Pretty incredible for one section of muscle.
TECHNOLOGY IS GETTING INVOLVED TOO
Today, this process doesn't necessarily depend entirely on a grader's eyes.
USDA has approved vision-grading instruments that can help predict marbling scores for Prime, Choice and Select, apply Yield Grades 1 through 5 and measure ribeye area.
USDA says these technologies are intended to improve consistency and uniformity in carcass evaluation.
And the system may be evolving even further.
In July 2026, USDA announced that it was seeking input on potential updates to the U.S. Standards for Grades of Carcass Beef.
USDA specifically noted that beef production, quality-assessment methods and consumer preferences have changed significantly.
So even this long-established grading system is being reconsidered as the beef industry changes.
HERE'S WHAT WE'RE QUESTIONING
We don't have a problem with USDA grades.
They're useful.
They give the beef industry and consumers a standardized way to communicate certain characteristics of a carcass.
But we do think consumers should understand exactly what that shield tells them.
And, maybe more importantly:
What it doesn't.
When you see:
USDA PRIME
it's easy to read that as:
This is the best beef.
But "best" depends on what matters to you.
If your only question is about the characteristics USDA's quality grade measures, that shield gives you useful information.
But what if your definition of premium beef also includes:
How the animal lived?
What it ate?
Whether added hormones were used?
Whether antibiotics were used?
Whether it lived on pasture?
How it was handled?
Where it was raised?
Where it was processed?
How traceable that animal is from ranch to table?
The USDA quality grade doesn't answer those questions.
It wasn't designed to.
And that's the part we think more people should know.
OUR DEFINITION OF PREMIUM STARTS BEFORE THE STEAK
At Falula Farm, we care about the beef itself.
Of course we do.
We care about marbling.
We care about tenderness.
We care about flavor.
We care about producing an exceptional steak.
But we don't believe the definition of premium beef begins when someone looks at a carcass.
We think it begins with the animal.
Our grass-fed cattle roam more than 3,000 acres of pasture in Bear Lake, Utah.
They breathe crisp mountain air and drink natural spring water.
They're raised without added hormones or antibiotics.
They're cared for by fourth- and fifth-generation ranching families who know the land and know the herd.
And when the time comes, each animal is thoughtfully processed here on the same ranch it called home, one at a time, in our USDA-inspected facility.
No mass production.
No conveyor belts.
Then the beef is aged for 14 days before being hand-cut, vacuum sealed, labeled and frozen.
To us, all of that is part of what makes beef premium.
The steak matters.
But so does the life behind it.
THE BEEF REPORT BOTTOM LINE
USDA Prime means something.
It just might not mean what you thought it meant.
Prime, Choice and Select are legitimate USDA quality grades based on defined carcass characteristics, with marbling playing a major role.
But a Prime shield does not by itself mean:
No added hormones.
No antibiotics.
Grass-fed.
Pasture-raised.
Low-stress handling.
Locally raised.
Those are different claims and different pieces of the animal's story.
So the next time you see that shiny USDA PRIME shield, don't ignore it.
Understand it.
And then ask the next question:
What else do I know about the beef behind it?
Because we don't think premium should describe only what happened after an animal became a carcass.
Premium should describe the life that came before it, too.
