Covance, a scalpel for hire, imprisons thousands of monkeys in its laboratories and subjects them to tests for everything from drugs to industrial chemicals for its clients. Historically, it was the largest importer of nonhuman primates into the U.S., until Envigo (above) acquired the branch of the company that imports, breeds, and sells animals for use in experimentation.
Covance clients include Tulane National Primate Research Center, Walter Reed National Military Medical Center, MRIGlobal, MPI Research, and NIH, which has given Covance $8,366,307.91 since 2008.
The company has a list of animal welfare violations a mile long. In 2016, for instance, the USDA fined it $31,500 after 13 macaque monkeys died of hyperthermia in two separate incidents in which no one noticed malfunctioning thermostats, causing rooms to overheat. For nearly a year, a PETA eyewitness worked in a Covance-owned laboratory owned where workers struck, choked, and screamed at terrified monkeys. They slammed primates into cages and sprayed them with pressurized hoses. The company was fined $8,720.
Hazelton Laboratories, as Covance used to be known, was responsible for three shipments of Ebola-infected monkeys, causing an unprecedented Ebola outbreak in Reston, Virginia—a suburb of Washington, D.C.—after dozens of macaque monkeys suddenly died and four workers were infected with a previously undiscovered strain of Ebola. Hazelton renamed itself Covance after the scandal.
