I used to work for a preclinical pharmaceutical company and our primary model was monkeys (macaques like rhesus and cynmolgus). We worked on drugs for cancer, Alzheimer’s, lupus, and more.

We had full time 24/7 vets, regular checkups, enrichment programs, and the techs would constantly give the animals treats and were very passionate about the most humane treatment. We got surprise inspected by the FDA and others in order to keep our GLP and AAALAC status and we worked with some major companies who would not work with us if we lost our status.

Euthanasia was a big part of many studies because they need to necropsy the animals so they can see what the drugs to do parts of the body.

This mention of “destroyed” seems much more harsh than what I experienced in the labs. Burning testicles is brutal bullshit - what the hell are they even testing?! This lab sounds like a fucking shit show!!!
