There is no requirement to disinfect dissection equipment BEFORE being dispensed to a class. It is important that dissecting equipment be thoroughly clean and rust free before being issued to students for a dissection, to reduce the likelihood of any infection if the user were to cut or stab themselves.
The cleaning process occurs at the end of the dissection and the implements stored clean and dry ready for the next session.
After the dissection if blood is present on dissecting equipment it is desirable to soak them first in disinfectant. Otherwise washing in hot soapy water or putting them through the dishwasher is recommended practice. After washing, the dissecting instruments can be soaked in 70% v/v ethanol for 20 minutes as an optional additional disinfectant and to avoid equipment from rusting. Soaking in a bleach solution is not suitable as bleach will cause metal instruments to corrode.
