Please see the following statement from PETA Senior Vice President Kathy Guillermo regarding a U.S. Department of Agriculture (USDA) citation issued to Bronco Research Services LLC in Fort Collins, Colorado, a contract testing laboratory owned by animal experimentation giant Inotiv, for a critical violation of the federal Animal Welfare Act. Inotiv posted this inspection report on its website as part of its settlement with the U.S. Department of Justice, following its 2024 plea to conspiring to violate the Animal Welfare Act and the Clean Water Act, and its agreement to pay the largest fine ever imposed under the Animal Welfare Act. Bronco staff noted that two beagles were “depressed and drooling” a day before they received the highest dose of a substance in an experiment. One was found dead the next day. The other was killed after being found “minimally responsive.” The facility’s animal care committee approved the experiment without a defined endpoint, so the dogs were dosed until death. Dogs who received a lower dose of the substance also suffered myriad effects, including “lethargy, drooling, regurgitation, and weight loss”:

Inotiv causes misery and death for animals everywhere it hangs a shingle, and every shack they operate should be run out of town and boarded up. USDA cited Inotiv’s Denver, Pa., facility recently for tormenting and killing rabbits, and its Cumberland, Md., beagle breeding operation was shut down, following a PETA undercover investigation. Inotiv should stop tormenting beagles, breeding rabbits, and importing endangered monkeys and pivot toward non-animal, human-relevant research methods.

PETA—whose motto reads, in part, that “animals are not ours to experiment on”—points out that Every Animal Is Someone and offers free Empathy Kits for people who need a lesson in kindness. For more information, please visit PETA.org or follow PETA on X, Facebook, or Instagram.
