An anonymous whistleblower says labs at Princeton University are regularly and badly mistreating their animals.
The anti-animal research group Stop Animal Exploitation announced the complaints were announced on Thursday. The group has asked the U.S. Department of Agriculture's animal welfare enforcement arm to investigate.
The complaint says the serious violations date at least to 2003.
Among the most serious are claims that marmosets were killed when they were sent along with their cage through a high temperature washing machine.
The report also says that a marmoset that escaped was clubbed.
The group says many of the biggest problems apparently went unreported. That would also be a violation of the federal Animal Welfare Act.
A Princeton spokesman says the university had not seen the allegations.
