"Kathy Guillermo, PETA's director of lab investigations, said the warning was significant because it was the first one to uphold "all of the years of complaints" the group made about animal treatment at the lab. Guillermo said the group sifted more than 1,000 pages of documents to identify the three cases, and didn't know how representative they were of care at the Oregon center or the nation's other seven primate centers. But "we suspect that there are problems like this ongoing," she said, and wishes the USDA had more inspectors to check labs."
