FAT scores every label using the same three-step analysis: What is disclosed? How credible is the disclosure? Who stands behind the label? This page walks the three steps for antibiotic claims on U.S. meat.

1 — What this label tells you (and doesn’t)

When shoppers see No Antibiotics Ever, Raised Without Antibiotics, or Antibiotic-Free, most assume the animals were raised without antibiotics — and that choosing those products helps reduce antibiotic resistance risk. That intuition is understandable, but antibiotic labeling is one of the most misunderstood areas of U.S. meat labels.

Residues are not the same as on-farm use. All federally inspected meat must meet U.S. residue limits. That means antibiotic-free can be misleading when it implies the meat is special simply because it has no unsafe residues. Residue compliance does not tell you whether antibiotics were used on the animal — only that withdrawal times and residue limits were met before slaughter.

What changed in 2017 (and what didn’t). The FDA’s Guidance for Industry #213 and the Veterinary Feed Directive, fully implemented January 1, 2017, accomplished two things: they removed growth-promotion uses for medically important antibiotics (those important for human medicine), and they brought medically important antibiotics in animal feed and water under veterinary oversight. They did not end the use of medically important antibiotics in food animals. Routine disease prevention and disease control uses, prescribed by a veterinarian, remain permitted — a distinction NRDC and others have argued functions as a continuing loophole.

The 2024 surge. FDA’s Annual Summary Report on Antimicrobials Sold or Distributed for Use in Food-Producing Animals showed total medically important antibiotic sales for food-animal use increased meaningfully in 2023 — with significant year-over-year growth in cattle. The post-2017 narrative that antibiotic use in U.S. food-animal production has been brought under control is no longer supported by the most recent data.

Most antibiotic claims on retail packages are voluntary marketing claims, not mandatory disclosures. The USDA does not directly verify raised without antibiotics; it relies on producer affidavits or third-party certification programs.

2 — How credible is the disclosure?

FAT assigns tiered, partial credit to antibiotic claims based on how rigorously they are verified.

Tier A — Full credit. Claims supported by rigorous third-party certification with audited records:

• USDA Organic — prohibits antibiotic use except to treat sick animals; an animal that receives antibiotics cannot subsequently be sold as organic.
• Certified Humane — prohibits routine antibiotic use; sick animals may be treated but the producer must follow specific protocols.
• Animal Welfare Approved (AWA / A Greener World) — no antibiotics for growth promotion or routine disease prevention; treatment of sick animals is permitted with documentation.
• Global Animal Partnership (GAP) step 4 and above — restricts routine and preventive antibiotic use.
• USDA Process Verified Program (PVP) for antibiotic protocols where the program has audited record-keeping standards.

Tier B — Partial credit. USDA-reviewed No Antibiotics Ever or Raised Without Antibiotics claims supported by producer affidavits or producer-maintained records, without independent audits.

Tier C — Minimal or no credit.

• Antibiotic-free — not a reliable term. Often used in ways that blur residues vs. on-farm use. FAT assigns no credit unless the producer defines the claim in a verifiable way (uncommon).
• No growth-promoting antibiotics — describes the legal baseline since 2017 for medically important antibiotics. Without further detail it adds little beyond what should already be true.
• Reduced antibiotic use / responsible antibiotic use — meaningful only when paired with a defined standard or audited program; standalone, these are marketing language.

3 — Who stands behind the label?

An antibiotic claim is only as credible as the entities that produced and processed the animal — and the regulators’ record on those entities. FAT surfaces the chain of accountability for every antibiotic-claimed package.

The processor and the FSIS National Residue Program. FSIS runs a public residue testing program that samples carcasses for antibiotic residues across species. Results are tied to the establishment number on the package. FAT links the FSIS establishment on the label to that processor’s public residue testing record. A raised without antibiotics claim on a package whose processor has recent residue violations carries less weight than the label alone would suggest.

The veterinary chain. Since 2017, medically important antibiotics in feed and water require veterinary oversight via a Veterinary Feed Directive (VFD) or veterinary prescription. The credibility of a no-antibiotic claim is meaningfully strengthened when the producer can document veterinary oversight protocols and audited VFD compliance, and meaningfully weakened when those records are not produced or not audited.

The brand owner and corporate parent. Vertically integrated producers (Tyson, Pilgrim’s Pride, Wayne-Sanderson Farms, Perdue) often run multiple brands at very different antibiotic-claim tiers within the same corporate parent. FAT traces brand ownership and notes when a single parent operates a Tier-A organic line and a Tier-C conventional line side by side.

Economic concentration. Four firms control roughly half of U.S. broiler chicken slaughter and a substantial share of pork and beef. Concentrated systems tend to standardize antibiotic-use protocols upstream of any retail label; the practical antibiotic regimen on the farm is often shaped more by the integrator than by the brand on the package.
