Farmers continue to use antibiotics on animals, which is not good for people who eat that meat. A war is in progress, and consumers are losing the war against meat antibiotics.
Antibiotics serve two purposes for large-scale meat farmers. These antibacterial agents allow farmers to raise animals in unsanitary, confined conditions that would otherwise sicken or kill them. They also allow factory farmers to use less feed. How much less feed? Without antibiotics, 175,550 more tons of feed would be needed to grow U.S turkeys lamented Michael Rybolt of the National Turkey Federation at 2008 hearings when the FDA tried to limit farm use.
Antibiotics and efficient food
It is thought that antibiotics increase weight in livestock by strengthening microbes that absorb nutrients, making food more “efficient.” (The same action of antibiotics may explain the human obesity epidemic postulate researchers.)
But the biggest harm of the animal antibiotic orgy on the farm is not human obesity. It is that it creates antibiotic resistant microbes, including E. Coli, salmonella, Methicillin-resistant Staphylococcus aureus (MRSA), C. difficile and others. Each year in the United States, at least two million people become infected with bacteria that are resistant to antibiotics. At least 23,000 people die each year as a direct result of these infections says the CDC.
Meat antibiotics profit
One of the reasons Pharma has not dedicated itself to developing new antibiotics to address the antibiotic resistant microbes afflicting humans is there’s no money in them. Unlike the statins and psychoactive drugs which have made Pharma arguably the most profitable industry in the world, antibiotics are only taken for a few days by humans.
But, of course, feeding them by the ton to farm animals which enriches large-scale meat farmers and Pharma is a different story. And, despite the efforts of public health agencies, hospitals, doctors and lawmakers to stop feeding healthy animals antibiotics at the expense of human health Pharma is still brazenly pushing the practice. It is an issue that often pits medical doctors against veterinarians.
A recent New York Times article details how Animal Pharma giant Elanco has launched a shocking new campaign called “Pig Zero” that tells farmers to treat pigs with antibiotics when they are healthy and before a disease outbreaks occurs. This is the exact opposite of what the CDC, doctors and public health officials urge.
U.S. industrial farmers turn nasty when the government tries to take away their antibiotics. In 2008, the egg, chicken, turkey, dairy, pork and cattle industries stormed Capitol Hill over the FDA’s attempt to prohibit the use of antibiotics called cephalosporins and they won. Antibiotics are downright “green” said the National Turkey Federation’s Rybolt at the hearings since less land is needed for crops.
After a decade-long battle with Bayer whose fluoroquinolone Baytril (enrofloxacin) was routinely used in poultry, the government managed to ban the antibiotic’s use in poultry water. But, and it is a big “but,” fluoroquinolones—including Baytril—are still clearly in use on U.S. farms, behind the public’s back. For example, the U.S. Department of Agriculture’s (USDA) National Residue Program for Meat, Poultry, and Egg Products, which tests for six fluoroquinolones, found enrofloxacin (Baytril) and ciprofloxacin (Cipro) residues in meat in 2014.
Also found by the USDA were residues of danofloxacin, an antibiotic not even approved for humans. Danofloxacin is so dangerous its label says, “Animals intended for human consumption must not be slaughtered within 4 days from the last treatment. Do not use in cattle intended for dairy production. A withdrawal period has not been established for this product in preruminating calves. Do not use in calves to be processed for veal.”
Though a 2013 FDA guidance required Pharma companies that make livestock antibiotics remove “growth production” from the label, the drugs are still routinely used for the new indication of “disease prevention” Senior Staff Scientist at Consumers Union Dr. Michael Hansen told me soon after the new guidance.
One example of the persisting uses is seen in feedlots, said Dr. Hansen. Feeding cattle grain instead of a more natural diet produces a high level of liver abscesses, he said and feedlot operators routinely give them the antibiotic Tylosin for the abscesses thus “preventing disease.” Tylosin reduces abscess incidence by 40 to 70 percent in such cattle according to medical journals.
Congress and antibiotics
The late Congresswoman Louise M. Slaughter, a microbiologist with a master’s degree in public health, said the 2013 guidance was “an inadequate response to the growing antibiotic resistant crisis caused by overuse of antibiotics on the farm.”
A Reuters investigation in 2014, after the 2013 guidance confirmed her suspicions. The investigation determined that Tyson Foods, Pilgrim’s Pride, Perdue Farms, George’s and Koch Foods were using antibiotics “more pervasively than regulators realize.”
Pilgrim’s Pride’s feed mill records show the antibiotics bacitracin and monensin are added “to every ration fed to a flock grown early this year.” (Pilgrim’s Pride threatened legal action against Reuters for its finding.) Also caught red-handed using antibiotics despite denying their use on its website, KFC-supplier Koch Foods’ Chief Financial Officer Mark Kaminsky, said “I regret the wording.”
Both the late U.S. Senator Edward Kennedy and Rep. Slaughter fought valiantly to curtail farm antibiotics but they had formidable enemies. Pharma and factory farmers spent over $17 million to block the bill they were supporting, the Antibiotics for Medical Treatment Act of 2007 said Rep. Slaughter. “It seems scarcely believable that these precious medications could be fed by the ton to chickens and pigs,” wrote Kennedy in the bill, noting that up to 70 percent of all U.S. antibiotics go to livestock.
Meat antibiotics transfer to crops
Nor do the meat antibiotics remain in the meat. Scientists at the University of Minnesota found antibiotic residues in corn, green onions and cabbage after growing them on soil fertilized with livestock manure. The drugs siphoned right up from the soil in just six weeks.
A University of Iowa study in 2010 found the resistant bacteria MRSA in 70 percent of hogs on farms studied and 64 percent of workers. Superbugs have even been found on an unopened soft drink can in a car following a poultry truck. Increasing antibiotic resistance is a big problem.
With pro-public health voices like Sen. Kennedy and Rep. Slaughter gone and a pro-industry administration in charge in the United States, it looks like consumers are losing the war against antibiotics. It is a war taking place on America’s farms.
