Recordings released by the Humane Society of the United States showed how animal testing was done by a laboratory in Mattawan, Michigan.
The Humane Society of the United States conducted an undercover investigation at the Charles River Laboratories from April 2018 to August 2018 and on Tuesday, March 12, 2019, released video of testing done on dogs provided by commercial breeders.
Humane Society of the United States President and CEO Kitty Block said in a written statement, “The disturbing findings at this facility are sadly not unique. Experiments are happening at hundreds of laboratories each year throughout the county, with more than 60,000 dogs suffering.”
The Humane Society said it was trying to release 36 beagles involved in a test of a fungicide by Corteva Agriculture, a division of DowDuPont.
On Wednesday, officials at the Charles River Laboratories released a statement saying that it follows all federal laws and international standards in its testing procedures.
"Charles River Laboratories operates our facilities in a way that is consistent with our commitment to the welfare and ethical treatment of the animals in our care," the company said in the statement. "As animal caregivers and scientific researchers, we are responsible to our clients and the public for the health and well-being of the animals under our stewardship, and we strive to fulfill that responsibility on a daily basis."
Animal testing is legal and required by many governmental agencies, such as the Environmental Protection Agency and the Food and Drug Administration.
The Humane Society said the testing is done to determine toxicity levels of pesticides, drugs and other products.
Both Dow and Corteva issued statements via Twitter regarding the Humane Society report. The companies said that they follow the law regarding testing, and have taken steps to reduce the use of animals in those operations.
