Antibiotics benefit farm animals, but at what cost?

Should we just say “no” to antibiotics for farm animals?

Your veterinarian hands you a bottle of antibiotics after treating your cat’s abscess. “Finish them all,” he urges. If you fail to comply, you’ll be contributing to the development of antibiotic resistance. In which case it won’t be your cat’s health alone that suffers, but potentially yours, too. All this because of a biological process in which bacteria mutate, deftly avoiding the mechanism by which antibiotics would see them exterminated.

Antibiotic resistance is an emerging threat that has accelerated in recent decades. The rise of the so-called “superbug” (think MRSA) has struck fear in the heart of anyone who would overprescribe, misuse or otherwise abuse antimicrobial drugs.

Physicians, veterinarians, patients and their families have all been put on notice: Overuse antibiotics at the public’s peril.

Still, that hasn’t stopped the animal agriculture industry from feeding hogs and chickens and cattle their daily dose of antimicrobial drugs. Aimed at promoting growth and preventing disease, the use of antibiotics in farm animals has been a boon to animal agriculture. Animals grow bigger, faster and healthier. They succumb to fewer diseases. They need less feed. For a farmer, the calculus is simple: Animals cost less when we spike their feed with drugs to prevent diseases.

If you eat most commercially produced meat, you’ve reaped the benefits, too. You spend less on your protein, and your food supply isn’t as likely to contain excesses of harmful bacteria. The public is well served by our modern methods, it would seem.

But at what cost?

That’s what the Obama administration has been pointedly asking over the past year in its quest to ban antibiotics from being used in healthy animals. These animals don’t need the drugs to treat their diseases. Feeding them a daily dose of drugs only accelerates the onset of a health care crisis the vast majority of the medical establishment agrees is looming.

Indeed, this issue has been decades in the making, meandering through public Senate subcommittee hearings and closed-door FDA sessions. Books have been written. Papers peer-reviewed and published. White papers authored. Commissions formed.

Much like climate change’s plodding progress toward more widespread acceptance, the science underlying modern industrial animal agriculture’s antimicrobial utilization methods has been increasingly questioned over the past few decades. Nonetheless, the findings have only recently gained purchase at the political level.

In large part, that’s thanks to the Pew Campaign on Human Health and Industrial Farming. Consider the following points for a taste of its findings:

1. Up to 70% of U.S. antibiotics go to animals raised on industrial farms that aren’t sick, to offset crowding and poor sanitation. The practice promotes the development of deadly strains of drug-resistant bacteria that can spread to humans.

2. Food-borne bacteria are more dangerous in their antibiotic-resistant forms, because they are harder to treat and may require multiple antibiotic treatments, longer hospital stays and other interventions before finally being eliminated.

3. Antibiotic-resistant bacteria cost the U.S. health care system an estimated $4 billion to $5 billion per year.

4. Each year, 300,000 hospitalizations and 5,000 deaths are caused by food contaminated by dangerous pathogens and bacteria such as salmonella and E. coli, which are increasingly becoming antibiotic resistant.

… among other frightening results.

But the AVMA (American Veterinary Medical Association), which traditionally supports animal agriculture, disagrees. Here’s an excerpt from its position statement (on the subject of Obama’s proposed ban on non-therapeutic antimicrobials in animal feed):

“This type of broad-based ban is contrary to the practice of veterinary medicine and is not risk-based. As legislation concerning the use of antibiotics in animal agriculture is considered by Congress, it is imperative that decisions be made based upon the science supporting the issue.”

Essentially, my profession’s leading organization says there’s little evidence to show that Point 1 has anything to do with Points 2 through 4. Correlation has been established, as it has for human misuse of antibiotics and the development of bacterial resistance. Causality has yet to be teased out —— something nearly impossible to achieve, whether for human misuse or animal overmedication. Yet it’s on this basis that we are asked to limit our enthusiasm for the obvious: Treat agricultural species like we treat ourselves and our pets. Give them antibiotics only when they’re sick.

Then we’re subjected to the most offensive argument offered by an animal-health-supporting body:

“The AVMA opposes this legislation because it would increase animal disease and death — an unfortunate and unintended consequence — without assurance of improving human health. As defined within the text of the legislation, elimination of “non-therapeutic” uses of antimicrobials would disallow disease prevention and potentially control uses.”

It’s true: The animal agriculture industry keeps infections at a manageable level by tamping them down with routine antibiotic use. If this kind of legislation is enacted, I have no doubt our agricultural animals that currently consume drugs daily will be less healthy in the short term. And, yes, that has implications for human health, animal welfare and the price you pay at the supermarket. (Check out the antibiotic-free meats if you care to compare.)

Nonetheless, I believe the Pew people have put their finger on the pulse of industrial animal agriculture and found it artificially strong. Like me, they see antibiotic use not only as a threat to human health, but as an animal welfare issue in and of itself.

After all, antibiotic use in animal agriculture makes sense primarily because of how we crowd and transport our creatures. Remove the antibiotics, and more animals will surely get sick in the short term. But long-term, that only means the industry will be forced to reform how it houses and ships its “widgets.”

Yes, long-term, I predict the trend toward voluntarily paying more at the supermarket (as some of us do now when we buy our antibiotic-free meats) will become mainstream as we’re forced to revert to meats raised in less intensive, drug-addled, hormone-laced environments — for the good of our public health.

Even if it does shrink the wallet somewhat, how bad can it be if it ultimately means Americans are persuaded to eat less of what we currently overeat?

Dr. Court’s Comments:

I always recommend that my patients eat as organic as possible.  This includes buying meats that are antibiotic free.  The meat industry in this country has become like every other large industry; it is dominated by large corporations who will stop at nothing to make more money.  This includes mistreating the animals and feeding them drugs and other chemicals so their when they are sold per pound they weigh more and collect more profit.

It is shameful, but it occurs everyday on farms and in slaughter houses around the country.  Let’s forget for a minute that what is done to these animals is not humane and consider the consequences on your health.

Do you want to consume the meat of an animal that has been injected with drugs and chemicals? Where do you think these chemicals go?  If you consume the meat, they go into you, that’s where.  While the antibiotics may reduce bacterial loads in meat it can create problems for you.  It can alter your gut flora causing you to absorb undigested proteins, fungus, parasites and other things that are not conducive with healthy living.

This is not just a question of animal welfare and treatment.  This is a major health problem in the US and changing it would change our meat supply for the better and result in healthier people across the country.

While free range, antibiotic, organic meat is more expensive, it is also much healthier for you.  Isn’t your health worth it?

One response to “Antibiotics benefit farm animals, but at what cost?

  1. Interesting argument but there are other very important factors that we must consider and speak out load and clear.

    Hospitals and our homes are cleaned using very strong chemicals (biocides) that are said to kill helpful bacteria (sensitive to antibiotics) and not the resistant strains. Brewers are said to be using antibiotics that has promoted resistant strains colonising in alcohol and over enthusiastic hand washing result in dermatitis that colonise resistant strains.

    First we must advice our doctors and nurses to stop abusing antibiotics. Let us not forget that we allowed this culture of prescribing antibiotics for viral infections saying this is to prevent secondary bacterial infections. By encouraging this we have conditioned our patients to demand antibiotics for coughs and colds.

    In UK patients visit nurse-led clinics where their expectations are met when we say NO to antibiotics . The healthcare providers collect data from these satisfied “Clients” and claim the service offered by these clinic are the best in the world.

    Unfortunately our healthcare providers and politicians have not understood the role of a doctor, so it is time we explained why we are must remain as the “Custodians of Antibiotics”

    “A good doctor is the one who does not prescribe but try and find out what makes their patient ill”.

    By allowing medically untrained professionals, we are allowing this epidemic to explode into a major pandemic in the near future. This will not only be a major threat to our community but will ultimately bring our profession on its knee.

    Doctors who manage a dying sick child with these infections will probably understand this better because I think this is one of the saddest and the most difficult situation we will encounter.

    Let us not forget our contribution to the society as doctor is to “Postpone death because only God can save lives”, if we fail, I do not think our profession will exist despite the wealth of knowledge we assimilated in past sixty years.
