CHICAGO – A dozen animals died during experiments at Loyola University’s medical school between 2006-2007, the result of untrained lab workers and inadequate care, according to federal documents.

U.S. Department of Agriculture inspectors cited Loyola’s Stritch School of Medicine in suburban Maywood for 22 violations during three inspections from March 2006 through November 2007, according to USDA reports obtained by the animal rights group Stop Animal Exploitation Now.

The research in question was halted and problems were corrected, said Loyola spokesman Jim Ritter. USDA spokeswoman Jessica Milteer said inspectors returned to Loyola this May and found problems resolved. No fines were issued, but Loyola did get a warning letter, she said.

Still, Budkie faulted Loyola for repeat violations.

Treating research animals humanely is a top priority at Loyola, said a written statement released by the university.
