PRINCETON - New accusations suggest Ivy League institutions, including Princeton University, have violated the Animal Welfare Act.

The accusations come from a group called the Physicians Committee for Responsible Medicine. Using reports from the United States Department of Agriculture, it ranks Princeton as the second-worst Ivy League university in treatment of lab animals, primarily primates or monkeys.

USDA inspection reports dating back to the summer of 2009 accuse Princeton of inadequate veterinary care.

A spokesperson from Princeton issued a statement saying the university takes the care of animals very seriously, and strives to maintain the highest standards of care. He says animal research leads to breakthroughs that benefit people, the environment and other animals.
