Superbugs on the Rise, and Evidence Mounts Against Factory Farms

When Russ Kremer, a fifth generation hog farmer from Missouri, was gored in the knee by one of his Yorkshire boars, he figured it was a routine injury. But the cut got infected. His knee swelled up to twice its normal size, and his life hung in the balance as multiple courses of antibiotics over two months proved ineffective. Finally, treatment with a potent form of the antibiotic cephalosporin managed to beat back the multidrug-resistant superbug.

Research shows that people who work with livestock, like Kremer, are more likely to carry antibiotic resistant bacteria on or in their bodies, posing a risk of serious infection. But they’re not the only ones at risk. Two million Americans are sickened by antibiotic-resistant bacteria every year, and 23,000 die from these infections, according to a landmark CDC report published last week. Another recent study from Johns Hopkins, published on the heels of the CDC report, showed that anyone who lives near industrial livestock operations, or fields fertilized with pig manure, is also at greater risk of getting infected by a superbug.

For decades, scientists have been teasing out the link between the abuse of antibiotics on livestock farms and the rise of superbug infections in humans. Here’s what the research tells us:

  • Antibiotic abuse on factory farms—where animals are routinely given antibiotics in an effort to compensate for crowded, unsanitary conditions, or make them grow faster--allows antibiotic resistant-bacteria to flourish in these animals, and is contributing to the rise of antibiotic resistance.
  • Antibiotic-resistant bacteria can, and do, escape factory farms and enter the community at large.
  • Some drug-resistant bacteria from animals can cause multidrug-resistant (superbug) infections in people; they can also spread resistance to other bacteria, creating more superbugs which can infect people.
  • Antibiotic resistance kills 23,000 Americans, sickens 2 million, adds up to $26 billion to our health care costs every year, and likely more than $55 billion in total costs to the U.S. economy.

Leading medical and public health organizations, including the American Medical Association, the American Academy of Pediatrics, and the World Health Organization, are speaking out against the abuse of antibiotics in the livestock industry. Eighty percent of all antibiotics sold in the United States, by weight, are used by the livestock industry—mostly for animals that aren’t even sick. The CDC, in its recent report, stated bluntly, “Much of antibiotic use in animals is unnecessary and inappropriate and makes everyone less safe.”

NRDC is pushing the FDA to do the right thing and stop the use of antibiotics in animals that are not sick. The agency has been stalling on this issue for decades. It’s recently proposed some weak, voluntary “guidance” on proper antibiotics use, but the amount of antibiotics used on industrial farms has been steadily increasing, while antibiotic use in humans has remained relatively steady.  

While the FDA continues to try to tiptoe around the issue, more consumers are starting to demand meat  raised without antibiotics, and businesses are responding. Russ Kremer, after his illness, converted his conventional operation into an antibiotic-free livestock farm. (He earned a Growing Green award from NRDC for his work.) Major businesses, including Chipotle, Applegate, Stonyfield Farms, Niman Ranch, and others, are working to provide their customers with products from animals raised without antibiotics. And bills are pending in the House and Senate that would curb the abuse of antibiotics in livestock operations.

Antibiotics are a precious resource. The more we misuse them, the less effective they become, leaving sick people with fewer, and more difficult treatment options. For nearly forty years, scientific evidence has been building toward the same conclusion: routinely administering antibiotics to animals that aren’t sick is putting human lives at risk. The FDA needs to move quickly to stop this practice, and preserve antibiotics for their original purpose—to be used as life-saving medicine.

If we hadn't begun the very inhumane and flawed system of factory farming all our livestock for greedy profit, antibiotics abuse would never have been an issue. Then again, going vegan or vegetarian is always an option to end both problems.
