The indictment of a number of members of an alleged worldwide monkey smuggling ring is sending ripples via the U.S. biomedical group. Final week, the U.S. Division of Justice (DOJ) charged two Cambodian wildlife officers and several other members of a Hong Kong-based primate provide firm with illegally exporting hundreds—and potentially more than 2000— cynomolgus macaques, an endangered species, to the US for analysis. The animals had been reportedly captured from the wild in Cambodia and falsely labeled as captive-bred.
The indictment, which carries a number of felony costs, will seemingly exacerbate the scarcity of those monkeys, utilized in every part from drug security testing to vaccine analysis, says Dave O’Connor, a virologist on the College of Wisconsin, Madison, who research infectious illness in cynomolgus macaques. Nonetheless, he says, the principle precedence must be stopping this unlawful commerce, each for the science and the animals themselves. “These kinds of unscrupulous actors give a black eye to an already closely scrutinized business.”
Animal advocacy teams are pushing to ban additional monkey imports till extra is understood about their provenance. And a few consultants within the biomedical group are suggesting shifting the breeding of this species of macaque to the US and amassing extra genetic and pedigree info on the monkeys that come from abroad. Additionally they say labs ought to discover methods to make use of fewer of those animals.
It’s unclear how lots of the animals in query have been utilized in analysis, however one in all two corporations that acquired them is the most important non-public provider of monkeys to U.S. analysis labs, Science has discovered. The corporate, Inotiv, tells Science that “whereas we don’t but know if these allegations will likely be confirmed true, Inotiv strongly condemns any and all unauthorized buying and selling/importation of endangered species. … To substantiate our screening processes are (and had been) stable, now we have plans in place to conduct the required audits to make sure excellence and supply transparency.”
Cynomolgus macaques, also called long-tailed macaques or cynos, are—by far—the monkey species most imported to the US. Almost 30,000 entered the nation final yr, in accordance with knowledge from the U.S. Facilities for Illness Management and Prevention (CDC), which regulates the import of nonhuman primates. Most cynos are utilized by pharmaceutical and biotechnology corporations. (Rhesus macaques, one other closely used monkey species in U.S. biomedical analysis, are largely utilized by the tutorial group, which largely obtains them from nationwide primate analysis facilities.) Cynos are additionally the principle monkey species imported to Europe for analysis. They’re sometimes bred in giant services in Asia.
China was once the principle provider of cynos—exporting roughly 30,000 in 2018—however the nation shut off its provide throughout the pandemic, which consultants have attributed to the commerce battle with the US and China’s want to beef up its personal biomedical business. A number of international locations, largely in southeast Asia, stepped in to fill the hole. Cambodia now exports the most important share of cynos—greater than 29,000 in 2020, the overwhelming majority of which had been shipped to the US.
The pipeline is probably going not sustainable. Although the precise variety of cynos within the wild is unclear, the Worldwide Union for Conservation of Nature downgraded the standing of the monkeys from susceptible to endangered this yr, citing rising demand from the analysis business as an element that might incentivize unlawful commerce.
The necessity for cynos has certainly grown, particularly throughout the pandemic. The species was one of many fundamental animal fashions employed to test COVID-19 vaccines, and researchers are more and more utilizing the monkeys to check Alzheimer’s, Parkinson’s, and different ailments. “There’s a sky-high demand for these animals,” O’Connor says.
Which may be what’s fuelling the alleged unlawful commerce in Cambodia. In response to the DOJ indictment, two high-ranking staff of Vanny Sources Holdings, a Hong Kong-based firm that breeds monkeys for analysis, paid hundreds of thousands to black market suppliers and Cambodian wildlife officers to seize 1000’s of cynos from nationwide parks and different protected areas of Cambodia, and to pretend their paperwork to point the animals had been bred in captivity.
Almost 1500 of those “laundered” cynos arrived in the US from 2018 to 2020, in accordance with the indictment, with probably a whole lot extra in 2021. They seem to have ended up at services in southern Florida and southern Texas. The businesses operating the services aren’t named within the indictment, however in a submitting with the U.S. Securities and Trade Fee final week, Inotiv disclosed that its principal provider of nonhuman primates was the goal of the DOJ probe, indicating that the corporate will get most of its monkeys from Vanny.
Final yr, Inotiv bought the foremost analysis animal provider Envigo (under fire recently for a sequence of animal welfare violations at one in all its beagle breeding services), making it the world’s largest provider of nonhuman primates for analysis. The corporate at present homes greater than 9000 monkeys—the overwhelming majority cynos—which it sells to non-public and tutorial labs.
If monkeys are for use in analysis within the U.S., there’s a duty to make sure they’re nicely cared-for … and sourced responsibly.

Cindy Buckmaster, a spokesperson for People for Medical Progress, which advocates for the usage of animals in scientific research, says there’s not a lot that corporations like Inotiv—or the labs they promote to—can do to test the provenance of the animals they obtain. “We have now to take the documentation at face worth,” she says. “The whole lot else is past our management.”
Nonetheless, she calls the alleged unlawful import of cynos “horrible” for the animals, and a violation of the belief each the scientific group and the general public put in animal analysis. She says wild-caught monkeys carry viruses that might infect different animals they’re housed with or people. They usually’re liable to stress simply from being round folks for the primary time, which might lead to “very completely different knowledge.”
Final week, the animal rights group Folks for the Moral Therapy of Animals requested CDC to droop all nonhuman primate exports from Cambodia. On Monday, it requested the U.S. Nationwide Institutes of Well being “to find out the exact origin of each [cyno] imported from Cambodia since 2017 and at present in publicly funded laboratories.”
In an announcement launched final week, Cambodia’s ministry of agriculture mentioned it was “shocked and saddened” by the indictment, and that it was dedicated to upholding all legal guidelines governing the worldwide commerce of animals. It additionally denied that any of its exported monkeys had been captured from the wild.
“If that is the response from the availability aspect, then we expect there must be a lot stricter controls on the demand aspect,” says Eric Kleiman, a researcher on the Animal Welfare Institute, an animal advocacy group that has intently adopted the difficulty. “If monkeys are for use in analysis within the U.S., there’s a duty to make sure they’re nicely cared-for… and sourced responsibly.”
Sarah Kite, the co-founder of Motion for Primates, a U.Ok.-based advocacy group, agrees. She notes the European Union is poised to go a legislation this month that may ban the import of all wild-caught animals and their offspring—and says the US ought to do the identical. “That’s the one means to make sure they’re not getting wild-caught animals,” she says. “The analysis group must be held accountable for what’s occurring to this species.”
O’Connor suggests one resolution: making certain that every one captive-bred animals have in depth pedigree information, which might be saved in a world registry. He additionally suggests genotyping each monkey utilized in a analysis research to raised hint their origins.
Main pharmaceutical and biotech corporations contacted by Science both declined to touch upon the difficulty or didn’t reply.
“I believe [the indictment] goes to constrict the pipeline much more,” says a U.S. advisor on business and tutorial monkey analysis who has labored within the subject for many years however requested to not be named due to considerations of damaging relationships together with his shoppers. The U.S. biomedical group ought to spend money on breeding these animals domestically, he says. “We have to migrate away from delivery an animal from midway all over the world, the place we will’t management the place it got here from.”
However the group additionally must focus extra on decreasing the variety of monkeys it makes use of, he says. That might be completed by designing research that require fewer animals, and dealing with regulators to require fewer of those animals for analysis corresponding to drug security research. “That’s simpler, sooner, and cheaper than increase an even bigger pipeline.”
