In most cases animals are euthanized at the end of their studies. If animals are not euthanized, the final disposition must be indicated in the Animal Usage Form. Euthanasia must be performed using methods approved by the IACUC. 

IACUC will euthanize small animals at no charge for investigators; farm animal euthanasia will be charged time and materials. These euthanasias are performed on IACUC's schedule. If investigators wish to schedule euthanasia for the purpose of collecting tissues, IACUC will charge for that as a veterinary special service.  IACUC provides carbon dioxide euthanasia chambers in most of its animal facilities.  Investigators should be familiar with the use of these chambers.

Carcass disposal

Animals that have died or are euthanized and are to be disposed of must be placed in a sealed plastic bag or glove and then placed in the red bag within the red biohazard container located in the animal morgue coolers. Do not place animal tissues or other full biohazard bags in the red barrels left outside of the cooler. Place your bags in the barrels kept inside the cooler. Do not put bags on the floor of the cooler. All bags and tissues must be placed in a red plastic barrel lined with a biohazard bag. There is a 50 pound limit on how much can be placed in these containers. Larger animals must be sectioned. It is essential that all animals be carefully examined to determine that they are dead prior to placing in the bag. Animals euthanized with ether must be kept in a fume hood for 30 min to evaporate the ether before they are placed in the morgues to prevent ethafume explosions.

If IACUC finds a dead animal, the investigator will be notified. The animal death is recorded on the cage card. The bag will be marked and placed in the "save" side of the cooler. Saved carcasses are held for 48 hours and are disposed of if not claimed by the investigator.
