Earlier than changing into secretary of the US Division of Well being and Human Companies and chief of the Make America Wholesome Once more motion, Robert F. Kennedy Jr. was a swashbuckling environmental legal professional who repeatedly took goal on the meat trade. He sued giant meat corporations and the Environmental Safety Company over water air pollution from manufacturing unit farms, and criticized manufacturing unit farming for its “unspeakable” animal cruelty and overreliance on feeding animals hormones and medicines.
For over a decade, a gaggle of meals security, environmental, and animal welfare nonprofits has petitioned the US Meals and Drug Administration — which Kennedy now oversees — to ban using probably the most controversial of these medication: ractopamine hydrochloride.
Fed to pigs within the ultimate weeks of their lives, ractopamine hurries up muscle achieve in order that pork producers can squeeze extra revenue from every animal. However the drug has been linked to extreme opposed occasions in pigs, together with trembling, reluctance to maneuver, collapse, lack of ability to face up, hoof issues, problem respiration, and even loss of life. It additionally carries a variety of environmental and human well being considerations.
Earlier this yr, the FDA denied the petition to ban the drug, arguing that present laws guarantee a “cheap certainty of no hurt to customers.” Whereas the company doesn’t dispute that ractopamine can hurt animals, and it halved the utmost dose in pigs in 2006, it has argued welfare points will be mitigated by merely asking meat producers to deal with ractopamine-fed animals extra fastidiously — a response that the petitioning organizations known as “toothless.”

The FDA didn’t reply to a request for remark in time for publication. Elanco, the pharmaceutical firm that developed ractopamine, didn’t reply to an interview request for this story.
Whereas 26 international locations have authorized ractopamine use in livestock, greater than 165 have banned or restricted it, and lots of have set restrictions on or have altogether prohibited the import of pork and beef from ractopamine-fed animals — actions which have set off commerce disputes. The bans stem primarily from considerations that the hint quantities of the drug present in meat may hurt customers, particularly these with cardiovascular situations, since ractopamine belongs to a category of medication (beta-agonists) that may improve individuals’s coronary heart charges.
There’s solely been one tiny examine on ractopamine in people who took the drug instantly, which European regulators — vulnerable to taking a precautionary method with new meals components — say is inadequate to show its security. Chinese language scientists are involved in regards to the drug as a result of its residues focus at larger charges in pigs’ organs, that are extra generally consumed in Chinese language diets.
The heated worldwide debate led one crew of biotechnology researchers to name ractopamine “essentially the most controversial meals additive on this planet.”

Daniel Waltz, managing legal professional of the Animal Authorized Protection Fund — one of many organizations petitioning the FDA to ban ractopamine — advised me it looks like simply the form of factor Kennedy would need to prohibit. “So why isn’t the FDA leaping on the alternative to do one thing about ractopamine?” Waltz stated.
Kennedy and the broader MAHA motion have lengthy elevated fears over prescribed drugs and meals chemical compounds, and it may typically be tough to parse their legitimate considerations from their harmful conspiracy theories. However he doesn’t seem to have ever publicly criticized ractopamine, and it’s unknown whether or not it’s even on his radar.
Given the dearth of trials, ractopamine’s menace to human well being is unclear, and cheap individuals can disagree on how authorities companies ought to deal with it. However there’s a transparent case to be made that ractopamine should be banned due to its terrible results on animals. The FDA’s determination to proceed to permit it in meat manufacturing represents a missed alternative to problem the manufacturing unit farm system that Kennedy has lengthy railed in opposition to, and to ban a chemical that nobody — besides the trade — actually needs.
“Ractopamine divides the world”
There’s ample real-world proof that ractopamine will be horrible for pigs.
Over an 11-year interval, the FDA acquired stories that over 218,000 pigs fed ractopamine suffered opposed occasions, like trembling, an lack of ability to face up, hoof issues, and problem respiration. That’s a comparatively small share of the billion or so pigs raised and slaughtered for meat throughout that point interval, however the quantity solely contains opposed occasions reported to the FDA — many extra may’ve occurred with out being reported. The subsequent most reported drug had a bit over 32,738 instances spanning 24 years.
The FDA has stated that stories of opposed occasions don’t set up that the drug brought about the consequences — basically that it’s correlation, not proof of causation. However shortly after the drug got here onto market, the FDA additionally acquired stories of an uptick in ractopamine-fed pigs unable to face or stroll at slaughterhouses.
Some research, together with a pair carried out by the drugmaker — Elanco — have proven that ractopamine is related to a variety of points in pigs, together with hoof lesions, fatigue, elevated aggression, and metabolic stress. Over time, Elanco has added warning labels that ractopamine-fed pigs are at an elevated threat of fatigue and lack of ability to stroll.

On the similar time, a literature evaluation by Elanco staff and college researchers taking a look at ractopamine research discovered it had minimal impact on pig mortality, inconsistent results on aggression and acute stress, and combined outcomes on a variety of physiological responses, like cortisol and coronary heart charge, with some analysis displaying little to no results, and others displaying reasonable results. The scale of the dose — and the way staff deal with the animals — had been usually necessary elements. Elanco has up to date its label to make clear that there’s no profit to feeding pigs greater than the bottom dose.
There’s additionally some proof to counsel ractopamine negatively impacts the welfare of cattle, a few of whom are fed the drug.
Much more than considerations over animal welfare, the uncertainty over ractopamine’s impact on customers’ well being has courted worldwide controversy. These considerations have led to international locations rejecting shipments of US pork and beef; Taiwanese lawmakers throwing pig intestines at each other and mass protests in a dispute over the nation’s determination to permit US pork imports from ractopamine-fed pigs; and a extremely contentious, multiyear debate on the United Nations-run Codex Alimentarius Fee, which units meals requirements necessary for worldwide commerce.
By the late 2000s, quite a few international locations had restricted imports of meat from ractopamine-fed animals, which posed a monetary menace to the US meat trade. So the US Division of Agriculture spent 5 years advocating for the Codex fee to approve most residue ranges of ractopamine in beef and pork as secure, which might give the US extra authorized leverage to problem different international locations’ import bans.
The fee’s combat over ractopamine was “actually, actually ugly,” Michael Hansen, a senior scientist at Customers Union — the writer of Shopper Reviews — who attended fee conferences, advised me.
European Union officers argued there wasn’t sufficient knowledge to make sure customers could be secure from ingesting hint quantities of ractopamine. Whereas the drug had been examined on numerous animal species, just one human scientific trial had been carried out in 1994, which included simply six wholesome younger males taking the drug, one in every of whom dropped out after complaints that his coronary heart was pounding.
In response to the trial, an FDA official on the time acknowledged that “the information from this examine don’t present enough assurance that the anticipated ractopamine ranges in meat merchandise will likely be with out cardiovascular pharmacological results in man.”
In 2012, the UN fee narrowly voted to set most secure ractopamine residue ranges in beef and pork by a margin of simply two votes — an uncommon consequence for a fee that traditionally ran on consensus. China and EU representatives, Hansen advised me, had been livid. US meat trade teams and the USDA secretary on the time, Tom Vilsack, cheered the choice.
Writing in regards to the fee combat, commerce lawyer Michael Burkard wrote that ractopamine “divides the world.”
Shortly after the Codex vote, Taiwan loosened its restrictions on imported beef from ractopamine-fed cattle, although China, Russia, and the EU preserve their bans. The US pork trade has tailored. Some corporations have devoted total slaughterhouses to ractopamine-free pigs, whereas others have phased out ractopamine fully. Within the early 2010s it was estimated that 60 to 80 p.c of US pigs had been fed ractopamine, however that determine has seemingly since gone down.
Nevertheless, ractopamine stays controversial and the topic of commerce disputes; simply final yr, China blocked shipments of US beef that contained traces of the drug.
The combat over ractopamine is a microcosm of a broader downside within the meat trade: The federal government’s reluctance to control it.
Over the past century, meat corporations have reworked how animals are raised for meals. They’ve packed animals into crowded, sprawling warehouses; bred them to develop larger and quicker to the detriment of their welfare; saved huge quantities of their manure in open-air lagoons that leach into the atmosphere; and designed advanced drug regimens to maintain them alive in unsanitary situations or, like within the case of ractopamine, make a bit more cash off every animal.
At any time when customers and advocacy teams elevate considerations over the issues manufacturing unit farming has created, most of the time, a authorities company tasked with regulating it takes motion to defend the meat trade, not reform it.
Kennedy has gained notoriety as somebody unafraid to problem each the pharmaceutical and agricultural sectors. Whereas a few of his concepts are downright harmful, his critiques of manufacturing unit farming are largely proper. Prohibiting US meat producers from utilizing a drug that advantages the trade on the expense of animals — and probably customers — would present his grandiose guarantees to reform the American meals system are greater than empty rhetoric. Doing so could or could not make America more healthy, however it might make animals undergo much less.
