These are two of the most common claims on meat packaging, and they mean very different things depending on which animal you’re looking at. Here’s the straight story.
Antibiotics
”No Antibiotics Ever” (NAE)
This means exactly what it says—the animal was never given antibiotics at any point in its life. Not preventively, not therapeutically, never. If an animal gets sick and needs antibiotics to survive, it gets treated but is then removed from the NAE program and sold as conventional.
This is the gold standard for antibiotic claims and it’s verified through documentation and testing.
”Raised Without Antibiotics”
Same thing as NAE, different wording. The USDA treats these as equivalent claims.
Why It Matters
The concern with routine antibiotic use in livestock isn’t about residues in your steak—there are withdrawal periods before slaughter that prevent that. The issue is antibiotic resistance. Using antibiotics preventively in healthy animals (which conventional agriculture does) contributes to resistant bacteria that can affect human medicine. NAE programs eliminate that contribution entirely.
What Whole Foods Does
All meat at WFM is raised without antibiotics—ever. If an animal needs treatment, it’s separated from the WFM supply chain. This isn’t a premium upsell, it’s the baseline.
Hormones
The Species Problem
Here’s where it gets interesting:
Beef and lamb: Federal regulations allow the use of added growth hormones. So “no added hormones” on beef actually means something—the producer chose not to use them when they legally could have.
Pork and poultry: Federal regulations prohibit the use of hormones. So when you see “no hormones added” on chicken or pork, it’s legally required to also include the fine print: “Federal regulations prohibit the use of hormones.” Every chicken is hormone-free. It’s not a feature, it’s the law.
What Growth Hormones Do
In conventional beef production, hormones (natural and synthetic) are used to accelerate growth — the animal reaches market weight faster, which reduces feed costs. The most common are estrogen, testosterone, and progesterone implants.
Does It Affect the Meat?
The honest answer: the science is complicated and debated. The measurable hormone levels in treated vs untreated beef are both very low relative to what your body produces naturally. Whether that tiny difference matters long-term is an open question. If you’d rather not have it in the equation at all, buy hormone-free beef.
The Marketing Trap
Watch out for these:
- “Hormone-free chicken” — Meaningless. All chicken is hormone-free by law.
- “No antibiotics at the time of slaughter” — Weasel words. This only means antibiotics were stopped before processing, not that the animal was raised without them.
- “Responsibly raised” — Means nothing specific. No standard, no verification.
The Bottom Line
Antibiotics: “No Antibiotics Ever” is the real deal and it matters. Look for it. At Whole Foods, it’s already standard across all meat.
Hormones: Meaningful for beef and lamb, irrelevant for pork and poultry (already prohibited). If you’re buying beef elsewhere, “no added hormones” is worth paying attention to.
The rule of thumb: If a label claim doesn’t come with a specific, verifiable standard behind it, it’s probably marketing. The good stuff will say exactly what it means and have the documentation to back it up.
