Tampa, Fla. –

In a letter sent today, PETA urges University of South Florida (USF) President Rhea F. Law to end the school’s cruel, U.S. Navy-funded decompression sickness/oxygen toxicity experiments on animals and follow the lead of the National Institutes of Health, the U.S. Food and Drug Administration, and others by pivoting toward cutting-edge, non-animal research.

Public records show that USF experimenter Jay Dean has spent more than $1 million in tax funds inducing seizures in rats without administering analgesics, cutting into their abdomens, and drilling into their skulls to place various recording devices before killing them. These archaic experiments are scheduled to receive additional funding of nearly $760,00 through 2026, despite the U.S. Naval Medical Research Center admitting that test results from animals don’t mirror human results due to major physiological differences between species.

Efforts from PETA and other allies contributed to the early termination of similar Navy-funded experiments on animals at other institutions. State-of-the-art, non-animal research methods, including in vitro studies and analyses of human diver data, are widely available, cost-effective, and significantly more applicable to humans.

“Archaic experiments on animals are a sinking ship, and the Navy must stop wasting time, money, and animals’ lives on junk science that benefits no one,” says PETA Vice President Shalin Gala. “PETA calls on USF to join the national shift toward scientifically superior human-relevant research.” 

Since 2020, the Navy has wasted more than $5.1 million on decompression sickness and oxygen toxicity tests on thousands of animals at USF, Duke University, the University of Maryland, Baltimore, and the University of California, San Diego.

More than 100 U.S. Navy veterans previously joined PETA and nearly 90,000 PETA supporters in calling on the military branch to ban these cruel and wasteful experiments.

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.
