Preparation of Equipment for Dissections

Preparation of Equipment for Dissections: Is it now a requirement that all dissection equipment be disinfected BEFORE being dispensed to a class?

I usually put all items through the dishwasher after dissections and they come out completely clean. Is it required that we then disinfect the items after this process?

Preparation of Equipment for Dissections

Answer reviewed 15 December 2022

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.
