The University of Pennsylvania is committed to the humane care and treatment of animals. Per the USDA Animal Welfare Regulations (AWRs) and the Public Health Service (PHS) Policy IV.A.3., the University of Pennsylvania's Institutional Animal Care and Use Committee (IACUC) is required to review and investigate any concerns involving the care and use of animals resulting from reports by research and facility personnel or by public complaints. As such, the IACUC encourages the prompt (within 24 hours) reporting of concerns or incidents related to animal welfare. Allegations should be as detailed and specific as possible to allow for a thorough investigation. All concerns are reviewed regardless of how they are received.
