Warning of ‘Pig Zero’: One Drugmaker’s Push to Sell More Antibiotics

Warning of ‘Pig Zero’: One Drugmaker’s Push to Sell More Antibiotics

Facing a surge in drug-resistant infections, the World Health Organization issued a plea to farmers two years ago: “Stop using antibiotics in healthy animals.”

But at last year’s big swine industry trade show, the World Pork Expo in Des Moines, one of the largest manufacturers of drugs for livestock was pushing the opposite message.
“Don’t wait for Pig Zero,” warned a poster featuring a giant picture of a pig peeking through an enormous blue zero, at a booth run by the drugmaker Elanco.

The company’s Pig Zero brochures encouraged farmers to give antibiotics to every pig in their herds rather than waiting to treat a disease outbreak caused by an unknown Patient Zero. It was an appealing pitch for industrial farms, where crowded, germ-prone conditions have led to increasing reliance on drug interventions. The pamphlets also detailed how feeding pigs a daily regimen of two antibiotics would make them fatter and, as any farmer understands, a heavier pig is a more profitable pig.
The rise of drug-resistant germs, caused by overuse of antibiotics, is one of the world’s most nettlesome health predicaments. Excessive use of the medicines has allowed germs to develop defenses against them, rendering a growing number of drugs ineffective for people and animals. The practices of livestock farmers, who for decades have used huge quantities of the drugs deemed important to humans, have long been viewed as one of the roots of the problem, but the role of the companies that make the drugs has received less scrutiny.

Antibiotics continue to be an important part of the business of companies like Elanco, which spun off from Eli Lilly in September, its share price soaring to $33 from $24. While Elanco is developing antibiotic alternatives for animals, like vaccines and enzymes, the antibiotics promoted by the Pig Zero campaign are exactly the kinds that global public health officials are trying to curb. And Elanco is no outlier — its rivals are also urging aggressive use of their own antibiotic cocktails.

“The reality is that antibiotics and large-scale industrial farming really grew up together,” said Dr. Gail Hansen, a former state epidemiologist and state public health veterinarian in Kansas, who sits on advisory boards addressing antibiotic resistance. She equated the problem with climate change. “By the time people understand and believe it,” Dr. Hansen said, “it may be too late.”

Elanco had already been put on notice about the drugs used in its Pig Zero push. In 2015, the Food and Drug Administration warned Novartis Animal Health, which had been acquired by Elanco, that the same antibiotic cocktail was “unsafe” and “misbranded,” because it was being illegally marketed to fatten pigs, rather than to simply treat disease. One of the drugs, tiamulin, has been a top seller for Elanco; the W.H.O. views it as medically important to humans, but American regulators do not. Pig Zero trumpets the benefits of coupling tiamulin with chlortetracycline, a drug made by Elanco’s competitors that both American and international regulators consider medically important to humans.

In an interview at Elanco’s headquarters outside Indianapolis, Jeffrey Simmons, the chief executive, said the company had decided to change the program’s marketing and to stop distributing the Pig Zero brochure after The New York Times began asking questions about it.

“We’re trying to be stewards and leaders at the same time,” said Mr. Simmons, adding that the brochure “wasn’t misrepresentation, necessarily, relative to the label or the science, or how a farmer would look at it.”

Dr. Shabbir Simjee, Elanco’s chief medical officer, said drugs like those in the campaign “would never be administered” in a herd “without some animals being physically sick,” adding that “there would need to be some animals showing clinical signs.”

He likened treating a herd to caring for children in a nursery: “If one child gets sniffles, you usually find that the whole class ends up with a cold, and this is exactly the same principle.”

But children almost certainly would not all be treated with preventive antibiotics in such a situation, and many scientists believe animals often should not be treated that way, either.

The connection of overuse of antibiotics in livestock to human health takes two paths: As bacteria develop defenses against drugs widely used in animals, those defense mechanisms can spread to other bacteria that infect humans; and, resistant germs are transmitted from livestock to humans — through undercooked meat, farm-animal feces seeping into waterways, waste lagoons that overflow after natural disasters like Hurricane Florence, or when farm workers and others come into contact with animals.

New F.D.A. regulations put in effect in the waning days of the Obama administration prohibited farms from fattening livestock by lacing their feed with medically important antibiotics. The new rules, along with rising consumer demand for antibiotic-free meat, cut antibiotic use significantly in 2017. But such drugs are still routinely given to pigs and cattle, accounting for almost 80 percent of medically important livestock antibiotics in the United States and nearly 5,000 tons of active ingredient. Worldwide use is projected to keep rising sharply as growing middle classes in places like China and Brazil demand more meat.

Ellen Silbergeld, a professor at Johns Hopkins University, who has worked with the W.H.O. on drug resistance, called the continuing promotion of the drugs by pharmaceutical companies “very dangerous.”

“The reason they’re doing it, though, is money, honey,” she added. “That’s what it’s all about. That’s what it’s always been about.”

Now, the industry has an important ally in Washington: President Trump, who appointed one of Elanco’s former executives, Ted McKinney, as under secretary of agriculture for trade and foreign agricultural affairs. Mr. McKinney told international food safety regulators at a meeting last summer in Rome that they were too singularly focused on consumers, at the expense of pharmaceutical companies and research scientists working to meet growing global demand for food. “We have got to rededicate a focus on them as our customers,” he said.

In 2015, Mr. Simmons, Elanco’s chief executive, joined a White House summit meeting to pledge the company’s commitment to curbing antibiotic use.

Sylvia M. Burwell, then the health and human services secretary, hailed the gathering as a “hopefully historic step to protect the health of our nation.” Dr. Thomas R. Frieden, the director of the Centers for Disease Control and Prevention at the time, warned that antibiotic resistance “could result in the medicine chest being empty when we need it most.”

Mr. Simmons outlined Elanco’s lofty aims. “We’re going to create antibiotic alternatives,” he said, adding, “We believe strongly that there are solutions, there are pipelines, there are options.”

A farm boy from upstate New York, he was a nearly 30-year veteran of Eli Lilly when Elanco spun off last year with its 5,800 employees. His wife helps run a church food bank. Mr. Simmons sits in an unassuming cubicle on Elanco’s campus.

He refers to himself as a “purpose-driven leader” on a mission to fight hunger — echoing the megachurch founder Rick Warren’s best-selling book “The Purpose-Driven Life,” which Mr. Simmons has read and taken to heart. He uses social media to spread a sort of protein-affordability gospel: “#Protein is a nutritious part of a balanced diet, but many don’t have access to it,” he once wrote on Twitter. “We can/must change this!”

While microbiologists emphasize the urgency of fighting antibiotic resistance, agrochemical industry veterans like Mr. Simmons say it must be balanced against hunger and the world’s growing demand for food. He often recounts his time as an executive in Brazil, when an anguished guard in his gated community sought help feeding his two children.

“I’m not doing it for a paycheck or profits,” Mr. Simmons said
in an interview. “Purpose has to override that.”

(He does get a paycheck, though. His total compensation was $5.4 million last year.)

Financial disclosures for Elanco and its rival Zoetis, which spun off from Pfizer in 2013, show the two companies sell roughly $2 billion annually in livestock antibiotics. In Elanco’s case, antibiotic sales represent more than one-third of its overall business. Some antibiotics, like monensin, a top seller for Elanco, belong to a class not used in people, and thus are not considered a resistance threat. But so-called shared-class antibiotics, like chlortetracycline, are used in humans and animals, creating risk for resistant infections.

Mr. Simmons said that while Elanco “started as an antibiotic company,” antibiotics that are medically important for people and used in livestock feed now make up only 5 percent of its sales. “We’re not building our company on that 5 percent,” he said. But the company has also said that 12 percent of Elanco’s sales overall, including antibiotics used in feed and administered in other ways, come from medically important antibiotics.

While consumer demand has made developing alternatives an industry imperative, few companies are eager to cede ground on existing business.

Del Holzer, who was the director of meat and poultry for Elanco’s global industry food team from 2012 to 2017, said the company and its competitors want to take positive steps and look good, to a point.

“They want to do the right thing,” said Mr. Holzer, who now works for a division of the agriculture giant Cargill, an Elanco competitor that develops antibiotic alternatives. “But they say, ‘My bottom line is my shareholders will be really pissed at me.’”
