[Histonet] Tissue Contamination

[Garrey Faller]

I agree with the comments made.
How do Histotechs mitigate the risk?
Do they use water? Do they just place the forceps back into the hot well/holder at the embedder? What is the best way to ensure safe embedding by the Histotech?

Although rare, contaminants do end up in blocks. The grosser says it’s the Histotech at fault. The Histotech says it’s the grosser.

I once inspected a lab and I witnessed the use of a microbiology flame sterilizer to sterilize the Histotech forceps between biopsies.   Never seen that before.

Each case utilizes a new scalpel blade and forceps are rinsed in water between cases. I am not aware of any cross over of tissues between cases when utilizing these practices.
