“For decades, evidence had amassed that the widespread use of antibiotics to help chickens, pigs, and cattle grow faster — and survive the crowded conditions of factory farms — was causing bacteria to mutate and develop resistance to antibiotics. By 2009, US agriculture companies were buying up two-thirds of what are termed medically important antibiotics — those used in human medicine. This in turn has made those precious, lifesaving drugs less effective for people.

Over time, once easily treatable human infections, like sepsis, urinary tract infections, and tuberculosis, became harder or sometimes impossible to treat. A foundational component of modern medicine was starting to crumble. But it wasn’t until the mid-2010s that the FDA finally took the basic steps of requiring farmers to get veterinary prescriptions for antibiotics and banning the use of antibiotics to make animals grow faster — steps that some European regulators had taken a decade or more prior.”

…

“according to Matthew Wellington of the Public Interest Research Group, the FDA’s reforms went after the low-hanging fruit, and they didn’t go nearly far enough. Now, in a concerning course reversal, antibiotic sales for use in livestock ticked back up 7 percent from 2017 to 2021, per a new FDA report. The chicken industry, which had led the pack in reducing antibiotic use on farms, bought 12 percent more antibiotics in 2021 than in 2020.”

…

“In 2019, antibiotic-resistant bacteria directly killed over 1.2 million people, including 35,000 Americans, and more than 3 million others died from diseases where antibiotic resistance played a role — far more than the global toll of HIV/AIDS or malaria, leading the World Health Organization to call antibiotic resistance “one of the biggest threats to global health, food security, and development today.””

…

“The FDA and the US food industry have proven that they can make progress on the issue — but to keep antibiotics working, they need to do a lot more. That will require them to tackle beef and pork, two of the more stubborn and complex sectors of America’s meat system that just can’t seem to quit antibiotics, since doing so could demand substantive changes to how animals are farmed for food.”

…

“In the early 2000s, the nation’s fourth-largest chicken producer Perdue Farms began efforts to wean its birds off antibiotics, which it achieved in 2016 by changing chickens’ diets and replacing antibiotics with vaccines and probiotics. At first, chicken raised without antibiotics cost 50 percent more, but the company says it has since been able to all but close the cost differential.

In the mid-2010s, while Perdue was making progress, activists leveraged the momentum and successfully convinced McDonald’s to source chicken raised without medically important antibiotics. Tyson Foods, the nation’s largest poultry producer, then committed to reducing antibiotic use, contributing to a “domino effect” in which producers and restaurants made further pledges to reduce antibiotics in poultry, said Wellington.

By 2020, a little over half of America’s 9 billion chickens farmed for meat were raised without antibiotics, according to an industry survey.

The sea change in chicken production demonstrated it was possible to quickly scale down antibiotics in farming, but it didn’t do much to reduce overall use, as the chicken industry only used 6 percent of antibiotics in agriculture in 2016. And the momentum didn’t spread to other parts of the meat business, like beef and pork, which together account for over 80 percent of medically important antibiotics fed to farmed animals.”

…

“Chickens are slaughtered at just six or seven weeks old, so the chance they’ll get sick is lower than pigs, who are slaughtered at six months old, or cattle, slaughtered at around three years of age.

The chicken industry is also vertically integrated, meaning a company like Tyson or Perdue controls virtually every link in the supply chain, so making big changes like cutting out antibiotics is easier than in the more decentralized supply chain of beef. For example, the typical steer will change hands several times before slaughter, going from a breeder to pasture grazing to a feedlot, all of which make it harder to coordinate an antibiotic-free regimen. In the last few months of their life cattle are also fed a high-grain diet that they aren’t adapted to digest, which increases the chance they’ll develop a liver abscess, a condition that’s prevented with — you guessed it — antibiotics.”

…

“The pork sector, like poultry, is also vertically integrated, but the industry has largely opposed animal welfare, environmental, and antibiotic reforms. Antibiotics in pig production shot up 25 percent from 2017 to 2021.

There’s also no pork or beef giant that’s taken the antibiotic-free leap like Perdue did for chicken.”

…

“Aside from outright banning the routine use of medically important antibiotics to prevent disease, Wellington said he’d like to see the FDA take three actions: set a target of reducing antibiotic use by 50 percent by the end of 2025 (based on 2010 levels); publish data on antibiotic use, not just sales; and limit the duration of antibiotic courses for farmed animals.

An FDA spokesperson said specific reduction targets weren’t possible because the agency doesn’t know how many antibiotics farmers are using: “We cannot effectively monitor antimicrobial use without first putting a system in place for determining [a] baseline and assessing trends over time.” The agency right now only collects sales data, and it’s been exploring a voluntary public-private approach to collect and report real-world use data.”

…

“here’s a lot to learn from the Europeans: Denmark, the continent’s second-largest pork producer, has become the de facto case study in how to wean Big Meat off antibiotics. In the early 1990s, it started phasing out antibiotics in pigs with little impact on the industry. From 1992 to 2008, antibiotic use per pig fell by over 50 percent, and while pig mortality went up in the short term, by 2008 it had dropped back to near-1992 levels.”
