Pathological waste is defined as any recognizable human or animal body part, organs and tissue. If contaminated with radioactive material, such as an animal carcass labeled with tritum, it is not considered medical waste, but radioactive waste, which then cannot be placed into pathological waste containers. Pathological waste is placed in a biohazard container lined with a red bag.
Pathological waste is a category of biohazardous waste. The parent category includes infectious animal bedding/feces, human and/or animal pathogens and disposable items contaminated with human blood or body fluids.
