‘Serious risks’: Researchers join push against importing monkeys for drug testing

Must read

Dozens of researchers across Canada, including renowned environmentalist David Suzuki, have joined a growing chorus of voices urging the federal government to halt the importation of an endangered monkey species for medical research in Quebec.

A letter signed by 80 scientists, academics, doctors and students says testing on long-tailed macaques from Cambodia should be banned due to ethical concerns and potential public-health risks.

“A decade ago, chimpanzees, our closest primate relatives, ceased to be used for experimentation because using such animal ‘models’ could no longer be justified from scientific, ethical, and/or financial perspectives,” says the letter addressed to Prime Minister Justin Trudeau, his environment minister and the premier of Quebec.

The researchers say they are also concerned about “the serious risks of transmission of zoonotic pathogens” that could be associated with transporting macaques.

Their letter urges the federal government to end charter flights that have been bringing the macaques into Canada, and to adopt regulations banning the importation of all primates for biomedical testing.

It’s the latest group to add more pressure on Ottawa to suspend the monkey imports by Charles River Laboratories, a U.S.-based pharmaceutical giant that has a sprawling facility in Montreal.

The company announced in 2023 that it was halting macaque imports into the U.S., after it was subpoenaed in a case that involved the indictment of two senior Cambodian officials over what authorities described as “multiple felonies for their role in bringing wild long-tailed macaques into the United States.”

No charges have been brought against Charles River Laboratories, or any of its officials, and the company has said it will fully co-operate with the U.S. investigation.

At around the same time, imports of monkeys from Cambodia into Canada dramatically surged, with Statistics Canada data showing a 500 per cent increase in 2023 from the year before.

Environment and Climate Change Canada, the federal department responsible for monitoring commercial trade in wildlife, confirmed to the Canadian Press that Charles River Laboratories has imported 6,769 long-tailed macaques into the country between January 2023 and August of this year. The monetary value of these imported macaques is around $120 million dollars, according to Statistics Canada.

The department previously said that officials rigorously and closely inspect imports of foreign animals, including those brought in by Charles River Laboratories, and that all macaque imports so far this year have complied with federal and international wildlife regulations.
