By this time everybody knows—or ought to—that the non-therapeutic use of antibiotics in farm animals is a threat to human health. 

Using antibiotics to promote animal growth or reduce feed requirements is a bad idea.  Widespread use of these drugs induces microbial resistance, making the antibiotics ineffective against human disease.

So you would think that public health agencies would be falling all over themselves trying to reduce antibiotic use in farm animals.  No such luck.  Proposals to restrict use of antibiotics for therapeutic purposes runs up against the interests of meat and poultry industries. 

The best the FDA can do falls far short of what is needed.  Witness its pussy footing on cephalosporin drugs.

On January 4, the FDA proposed a final rule on use of cephalosporin drugs in animal agriculture.

The rule bans some “extralabel” (i.e., unapproved) uses of cephalosporin antimicrobial drugs in some food animals—cattle, swine, chickens, and turkeys. 

As the FDA’s press release explains, it is banning use of cephalosporins:

• At unapproved dose levels, frequencies, durations, or routes of administration
• In forms that are not approved for use in cattle, swine, chickens, and turkeys because they are intended for humans or companion animals
• For disease prevention

These are all good things but should do much more. 

Cephalosporins are used in humans to treat pneumonia, skin and soft tissue infections, pelvic inflammatory disease, diabetic foot infections, and urinary tract infections.

If bacteria are resistant to cephalosporins, doctors have fewer options for treatment and these are less effective or more harmful.

 What is troubling is that the FDA proposed a more restrictive ban in 2008 but reversed the decision under pressure from industry veterinarians.

As Food Safety News reports, the new order, which is scheduled to go into effect in April, follows a couple of previous notices published last year. 

In November, the FDA turned down consumer petitions calling for a ban on the non-therapeutic use of a broader range of antibiotics in farm animals. 

In December, the FDA admitted that it had given up a plan first announced in 1977 to withdraw approval for penicillin and tetracyclines in animal feed.

Apparently, the FDA has decided to try to get drug companies and the meat and poultry industries to reduce the use of antibiotics voluntarily.

Good luck with that. 

Philip Brasher writes in the Des Moines Register that the new restrictions will hit hardest on the chicken industry, which uses the drugs for disease prevention. 

He says the FDA’s 2008  proposal would have blocked hog producers from treating illnesses that aren’t listed on the label.   He quotes the chief veterinarian for the National Pork Producers Council:

We are pleased that FDA balanced the need to protect animal health with their concerns about resistance.

This is not about animal health.  Nobody is trying to stop the use of antibiotics to treat animal disease.  At issue is their use as growth promoters or feed savers.

Congresswoman Louise Slaughter (Dem-NY) understandably views the FDA’s action as “tepid.”  She has introduced the  Preservation of Antibiotics for Medical Treatment Act to deal with the problem of non-therapeutic antibiotic use.  Of the FDA’s proposal, she said:

This is a modest first step by the FDA…but we’re really just looking at the tip of the iceberg. We don’t have time for the FDA to ploddingly take half-measures. We are staring at a massive public health threat in the rise of antibiotic-resistant superbugs. We need to start acting with the swiftness and decisiveness this problem deserves.

We do indeed.  Her bill deserves much support.   Public health should not be left up to the meat, poultry, and drug industries to decide.

Addition, January 12: I missed the New York Times editorial on this issue:

It’s time for the F.D.A. to consider the public’s health as carefully as it considers the interests of intensive agriculture and pharmaceutical companies.

I was interested to read FoodSafetyNews this morning and learn about the FDA’s new count of the number and pounds of antibiotics used to promote the growth of farm animals used as food.

Because this is the first time the FDA’s Center for Veterinary Medicine has produced such a count, it is not possible to say whether the numbers are going up or down.  But the agency is now requiring meat producers to report on antibiotic use so we now have a baseline for measuring progress.

The FDA has been concerned about the use and misuse of animal antibiotics for some time now, so much so that in June it issued guidance on The Judicious Use of Medically Important Antimicrobial Drugs in Food-Producing Animals.

In the Federal Register notice announcing the guidance, the FDA explains:

Misuse and overuse of antimicrobial drugs creates selective evolutionary pressure that enables antimicrobial resistant bacteria to increase in numbers more rapidly than antimicrobial susceptible bacteria and thus increases the opportunity for
individuals to become infected by resistant bacteria. Because antimicrobial drug use contributes to the emergence of drug resistant organisms, these important drugs must be used judiciously in both animal and human medicine to slow the development of resistance. Using these drugs judiciously means that unnecessary or inappropriate use should be avoided….

In regard to the use of antimicrobial drugs in animals, concerns have been raised by the public and components of the scientific and public health communities that a significant contributing factor to antimicrobial resistance is the use of medically important antimicrobial drugs in foodproducing animals for production or growth-enhancing purposes.

The overuse of antibiotics in farm animal production was a key focus of the 2009 report of the Pew Commission on Industrial Farm Animal Production. Our conclusion: the overuse of antibiotics in animal agriculture is an enormous risk to public health and should be stopped.

The FDA report may be short and issued without comment, but it is a sign that the FDA is taking steps to address this serious public health problem.

I served as a member of the Pew Commission on Industrial Farm Animal Production which issued its final report in April 2008.  Our most important recommendation: reduce the widespread use of antibiotics as growth promoters and as a routine method of preventing infections.  Why?  Because of increasing evidence of human resistance to the kinds of antibiotics used in farm animal production and to related antibiotics.

You think everyone involved in production of farm animals understands the dangers of continued overuse of these drugs?  Not a chance.  A coalition of 20 meat producing groups has asked Congress not to restrict their use of antibiotics.  The American Meat Institute has issued a statement condemning our report.  The American Veterinary Medical Association (AVMA) has done even more.  It just issued its own report taking on the Pew Commission’s antibiotic recommendations.  Why the ferocity and why now?  Congress has submitted a bill – the Preservation of Antibiotics for Medical Treatment Act of 2009 (PAMTA) – that would restrict use of several antibiotics in farm animal production.

Ralph Loglisci, who was the Pew Commission’s communication director, has an excellent blog post dealing with the AVMA statement.  If you want to understand what all this is about, take a look at it.

While these debates continue, antibiotic-resistant bacteria are increasingly turning up in our food supply.  Tell your representatives to support PAMTA!

The Pew Commission on Industrial Farm Animal Production (of which I was a member) recommended as its #1 priority the elimination of antibiotics for promoting growth and other unnecesary purposes in farm animals.  I discussed this report in a previous post.

There is much fuss about this issue this week because the House is holding hearings on the Preservation for Antibiotics for Medical Treatment Act.  If passed, this will phase out the use of seven classes of antibiotics important to human health that are currently allowed to be used as growth promoters in animal agriculture.  The FDA testified in favor of the act.  So did members of the Pew Commission: Robert Martin, Fedele Baucio, and Bill and Nicolette Niman.

So who could possibly be opposed to such a good idea?  How about the American Veterinary Medical Association, for starters, apparently more worried about its members’ self interest than about sensible use of antibiotics.

Maybe we’ll get lucky and the Congress will do the right thing on this one.

Update July 16: Ralph Logisci, who helped staff the Pew Commission, posted a blog on the movement to ban non-therapeutic antibiotics on Civil Eats.  It goes into considerable depth on the issues and is well worth reading. And the Institute for Agriculture and Trade Policy (IATP) has just produced a report on eliminating the use of non-thereapuetic antibiotics in, of all things, ethanol production.  Who knew?  Turns out they use antibiotics to control fermentation.  Oops.  Not a good idea.  IATP says plenty of alternatives are available and the ethanol industry should adopt them.

July 20 update: in case you haven’t seen it, here’s the meat industry’s July 9 statement in opposition to the bill attempting to ban antibiotic use.

I attended a meeting at Cornell last week at which FDA Commissioner Robert Califf answered questions from faculty and staff.

He started out by remarking on the poor health status of Americans, despite our spending twice as much on health as any other country.  He noted the disparities in health status, particularly singling out the declining health of rural Americans.

In answer to questions from panel members and, later, from the audience, he said (my notes and paraphrase, unless in quotes):

• We have real health problems on the ground right now.
• The  big issue is chronic disease, on which we are “doing terribly.”
• We have to deal with the marketing of ultra-processed foods designed to make you hungry for more.
• On tradeoffs in trying to discourage ultra-processed foods: This isn’t like drugs with clear risk/benefit calculations.  Food research has big confidence intervals and less rigorous estimates. The FDA has lots of bosses.  The executive branch and Congress can overrule anything it does.
• One Health (the movement to treat human and animal health issues as parts of a whole) is essential to the future of humanity.
• Climate change has moved pathogens into areas where they didn’t used to be.
• Action on animal antibiotics stagnated as a result of the pandemic: “We are all sinners in this regard.”
• We need a global strategy; infectious diseases do not respect borders.
• ”There is a lot of rhetoric about food safety, but the systems do not come together as they should.
• There is too much financial influence on policy.  “Policy is everyone’s job.”
• A lot of people are making a lot of money on our food and health systems, but it’s not spent on the right things.
• On the Supreme Court’s overturn of Chevron: the FDA cannot extend its rulings beyond what Congress intended.  It will slow things down.
• “We should reserve most of our energy to do our jobs well.”
• Courage is important: we must have courage to do things differently.

Comment

I was impressed by his knowledge, thoughtfulness, and concern about public health issues, especially those around food, as well as his understanding of the current political barriers against using expertise and regulation to improve food systems and public health.

He used the occasion to encourage students to consider careers in the FDA and noted the remarkably low turnover of permanent staff.

Jerry Mande sent me a link to a report of remarks the Commisioner made in December: America has a life expectancy crisis. But it’s not a political priority (Washington Post), and also to Helena Bottemiller Evich’s report, FDA Commissioner says ultra-processed foods drive addictive behavior.

So the Commissioner is giving serious thought to these issues.  So are others: see Announcement below.

The big question: who at FDA will take the lead on all this?

The FDA has just undergone a major reorganization.

As of October 1, the Human Foods Program looks like this.

The big question: who will head the new Nutrition Center of Excellence?

My big hope: Califf will appoint someone to that position who shares his committment to reducing diet-associated chronic disease.  Fingers crossed.

Announcement

Senator Bernie Sanders (I-Vt.), announced that his Committee on Health, Education, Labor, and Pensions (HELP) will hold a hearing on the urgent need for the FDA to “adequately protect Americans – especially children – from unhealthy foods that are pushed on consumers by the food and beverage industry.”  Here is his invitation letter to Commissioner Califf and Deputy Commissioner Jim Jones, who heads the FDA’s Human Foods Program.

When: 10:00 a.m. ET, Thursday, December 5, 2024
Where: Room 562 Dirksen Senate Office Building. The hearing will also be livestreamed on the HELP Committee’s website and Sanders’ socials.

The USDA announces updated guidelines for substantiating claims on meat and poultry labels in these categories.

• Animal Welfare Claims
• Breed Claims
• Diet Claims
• Living or Raising Conditions Claims
• Negative Antibiotic Use Claims
• Negative Hormone Use Claims
• Source and Traceability Claims
• Organic Claims
• Environment-Related Claims

It says:

Animal-raising claims, such as “Raised Without Antibiotics,” “Grass-Fed” and Free-Range,” and environment-related claims, such as “Raised using Regenerative Agriculture Practices” and “Climate-Friendly,” are voluntary marketing claims that highlight certain aspects of how the source animals for meat and poultry products are raised or how the producer maintains or improves the land or otherwise implements environmentally sustainable practices…FSIS [USDA’s Food Safety and Inspection Service] last updated its guideline on these claims in 2019.

USDA’s new guidance says it “strongly encourages”

• The use of third-party certification to substantiate animal-raising or environment-related claims
• Substantiating “no antibiotics” claims by testing for antibiotics or using a third-party certifier who does the testing
• Providing data on soil or air quality studies to substantiate environmental claims

Comment

This guidance is voluntary.

This raises immediate questions about the antibiotic claim.  A study conducted by researchers and policy experts at George Washington University found 20% of cattle marketed as “raised without antibiotics” to have been treated with antibiotics.

You would think that fixing this situation requires mandatory regulation, not voluntary.

Groups concerned about animal welfare also object.  The Animal Welfare Institute wants stronger standards.

The ASPCA issued a press release: “ASPCA Condemns Long-Awaited USDA Guidelines that Fail to Meaningfully Improve Oversight of Animal Welfare Label Claims”

ASPCA’s labeling guide points out that claims for cage-free, humane-raised, and pasture-fed, for example,

which often appear on the packaging of meat, egg and dairy products, may indicate better animal welfare but lack strong standards and have no on-farm verification processes, meaning farm conditions and the treatment of animals vary widely across producers.

Voluntary means that producers can voluntarily ignore such guidelines.  Plenty of evidence suggests that many do.

We need a better system.

• The full guidelines.
• The advance Federal Register notice.

The FDA issued its most recent report on antibiotics late last year: 2022 Summary Report On Antimicrobials Sold or Distributed for Use in Food-Producing Animals, along with Antimicrobial Sales and Distribution Data 2013-2022.

It did this in response to public concerns about antibiotic use in food animals: if antibiotics are used at subtherapeutic doses, they might induce microbial resistance to drugs used to treat diseases in humans.

This is not a theoretical concern.  It’s a real problem.

It’s also a problem because the vast majority of antibiotics were used as growth promoters or to prevent infections in animals crowded together—not to treat disease.

In 2014 or so, the FDA ruled that medically important antibiotics could no longer be used as growth promoters in farm animals.  That rule went into effect in 2017.

The FDA’s good news: the amounts of antibiotics used in farm animals has declined since then.

Are medically important antibiotics still used for non-therapeutic purposes?

The report says that since 2017, zero antibiotics are administered for growth promotion.

If you wonder whether this is really true (as I do), consider that $11.2 million kilograms of antibiotics were used in food animals in 2022.  This is a decrease from the 15.6 million kg used in 2015, but still a lot.

Of these drugs, 63% are administered in feed, and 31% in water.

All antibiotics still used as growth promoters are supposed to be drugs not used in human medicine.

I’m not the only skeptic on this one.  See:

I.  The Bureau of Investigative Journalism’s Antibiotics in agriculture: The blurred line between growth promotion and disease prevention.

In an investigation published today, the Bureau revealed how US farm animals are still being dosed with antibiotics vital to human health, despite efforts to curtail such usage and combat the spread of deadly superbugs. We also found that a regulatory loophole means that using antibiotics to make animals fatter – a process known as growth promotion – is technically still possible, despite this practice being banned in January 2017.

II.  Nature: Antibiotic use in farming set to soar despite drug-resistance fears. Analysis finds antimicrobial drug use in agriculture is much higher than reported.

III.  Vox: Big Meat just can’t quit antibiotics: Meat production is making lifesaving drugs less effective. Where’s the FDA?

According to an analysis published in September by the Natural Resources Defense Council and One Health Trust, medically important antibiotics are increasingly going to livestock instead of humans. In 2017, the meat industry purchased 62 percent of the US supply. By 2020, it rose to 69 percent.

Does the FDA check?  It has guidance for industry on The Judicious Use of Medically Important Antimicrobial Drugs in Food-Producing Animals, but this guidance is non-binding.

Obviously, the FDA needs to do more.  Its officials told Vox:

I’m trying to keep up with what’s happening with cultivated meat.  So far, the FDA has approved a couple of cultivated chicken cell companies, and these are selling “chicken” in a couple of restaurants, one in San Francisco and the other in Washington DC.

The big issue: scaling cell production up enough to have product to sell.  It takes lots of cells–billions? trillions?—to make a portion big enough to eat.
