Consumers perceive antibiotic-free meat as a healthier, more ethical choice than meat from animals raised with antibiotics and pay higher prices for such meat. However, investigations reveal that many ‘antibiotic-free’ products in the United States are not what they claim to be.
I previously shared shocking figures released by the USDA’s Food Safety Inspection Service (FSIS) based on the results of a 2023 testing program that included 189 samples from 84 slaughter establishments in 24 states.
The FSIS found antibiotic residues in liver and kidney samples of 20% of cattle destined for the ‘Raised without antibiotics’ (RWA) market.
That is, approximately 20% of US beef claimed to be raised without antibiotics was being marketed with false claims.

What surprised me, when I stumbled upon that data, published in August 2024, was that it had not provoked any kind of outrage – or in fact any response at all – in mainstream media outlets.
Surely this was a scandal that consumers would want to know about?
It didn’t help that the figures were not published as a report but buried in the ‘Background’ section of an FSIS page announcing a comment period on a guideline for meat labelling claims.
This was not the first time antibiotic residues had been found in RWA meat and cattle. In 2022, researchers from the George Washington University reported that 15% of US RWA cattle contained antibiotic residues. Also in 2022, advocacy group Farm Forward found antibiotics in RWA beef purchased from Whole Foods.
In letters from the USDA to the companies found to be engaging in deceptive behaviour, obtained under freedom of information by Farm Forward, the USDA told the companies they may have produced misbranded product but would not be subject to any enforcement action.
In 2025, Farm Forward publicly named the companies with positive results, revealing that antibiotics were detected in beef declared ‘Raised without antibiotics’ from three of the four largest meat processors in the US.
In their April 2025 report, Farm Forward said JBS and Cargill continue to sell RWA, while Tyson abandoned some of its RWA brands in July 2024, after the USDA tests.
Smaller companies are also alleged to be continuing to use questionable claims, with Farm Forward stating that three smaller brands that market their meat as “no antibiotics ever” and “raised without antibiotics” continue to sell meat despite receiving positive results in the USDA survey and without announcing any changes to procedures, nor sharing any subsequent test results to verify their claims.
The USDA, which must approve all RWA claims before they may be used by a company, has not made any changes to its approval process and continues to rely on producers’ self-reporting of antibiotic use.
However, the FSIS states it now “strongly encourages meat and poultry establishments to substantiate such claims by implementing a routine sampling and testing program to test for the use of antibiotics in animals prior to slaughter.” Or, as an alternative, to obtain third-party certification that involves antibiotic testing.
This means that meat marketed as ‘antibiotic-free’ or ‘raised without antibiotics’ in the U.S. may continue to be affected by false and misleading claims. The USDA does not publicly disclose violations, nor penalise companies for mislabelling. As a result, consumers continue to pay premium prices for meat that may not be true to label.
Antibiotic-free meat: the global context
Antibiotics are used in meat production to prevent and treat bacterial infections in animals. In the United States, antibiotics are also used to promote growth and improve feed efficiency, allowing farmers to produce more meat with less feed.
However, the use of antibiotics as growth promoters is effectively banned in many other countries worldwide. Such bans aim to limit antibiotic use and curb the rise of drug-resistant bacteria, which pose major threats to public health.
In the U.S., the meat industry accounts for a significant portion of all antibiotics used in that country. For example, in 2020 it purchased 69% of the U.S. supply of medically important antibiotics, with just 31% being used for humans.
There is no publicly available information about the proportion of antibiotics that are used for prophylactic purposes, such as growth promotion, compared to treatment of already-sick animals in the U.S. However, compared to the European Union, the U.S. uses nearly double the quantity of antibiotics for livestock, based on 2020 figures.
‘Antibiotic-free’ meat is supposed to come from animals that have not received antibiotics at any stage in their lives. In the U.S., these products are labelled ‘Raised Without Antibiotics’ (RWA), a claim that is regulated by the U.S. Department of Agriculture (USDA) but which relies on self-attestation by meat producers.
Theoretically, under the USDA RWA program, if an animal falls ill and requires antibiotics, it is removed from the program by the farm operator, and its meat should not be sold under the antibiotic-free label.
Globally, only 20% of countries still use antimicrobials as growth promoters in meat production. In the European Union, antibiotics have not been permitted for use as growth-promoters since 2006, with China following suit in 2020.
There are partial restrictions in Australia, Canada, Uruguay, and Brazil, with most countries outlawing the use of antibiotics that are medically important for humans for use as livestock growth-promoters, while allowing other antibiotics to be used for such purposes.
A loophole related to the labelling and registration of feed additives exists in some countries. Feeds may contain undeclared low doses of antimicrobials, which are then unknowingly administered by farmers and veterinarians to their animals.
Globally, false claims of ‘antibiotic-free’ status may occur in any market where consumers pay a premium for meat labelled as such.
In short: USDA testing of animals destined for the ‘Raised Without Antibiotics’ market (RWA) revealed 20% of animals contained antibiotic residues 🍏 Companies were not named and no enforcement action was taken, despite the USDA telling companies they may have sold misbranded product 🍏 FSIS says it strongly encourages meat and poultry establishments to implement testing programs or engage with certifiers that use testing programs, however this is not mandatory 🍏 Purchasers of meat marketed as ‘antibiotic-free’ or ‘raised without antibiotics’ should be aware that these claims could be false 🍏
