An event that may have a negative impact on the wellbeing of Animals and was not foreshadowed in the approved project or activity.
An unexpected adverse event may result from different causes, including but not limited to:
- death of an Animal, or group of Animals, that was not expected (e.g. during surgery or anaesthesia, or after a procedure or treatment);
- adverse effects following a procedure or treatment that were not expected;
- adverse effects in larger numbers of Animals than predicted during the planning of the project od activity, based on the number of Animals actually used, not the number approved for the study;
- a greater level of pain or distress than was predicted during the planning of the project or activity;
- power failures, inclement weather, emergency situations or other factors external to the project or activity that have a negative impact on the welfare of the Animals.
