After histopathology, for how many years the formalin preserved wet tissues (biological specimen) has to be stored in archival and. Method of disposal of those tissues? Kindly help in this regard . Thank you in advance
It is difficult to give a straight answer when it comes to forensic material. Your own laws might give you diresctions. For the disposal these links might be of help: file:///C:/Users/Admin/Downloads/FormalinDisposal.pdf

The time duration varies depending on the conditions to which your tissue is stored but as long as the formalin is good the tissue will also be preserved. But my advice would be to utilize your tissues as soon as you can. Make the slides, view them, take pictures and store them in the cloud. That way you have immortalized your tissues. For disposal. by incineration or placing in the biohazardous labeled waste bin.
Hope this is helpful.

Hi Monika,
If your specimens are medico-legal related, it should depend on your institutional law regarding the specimen ownership and disposal. Concerning specimen integrity, prolonged formalin storage will harden the tissues and cause formalin pigments (artifacts). Should you need the wet specimens in the future, I would advise changing the formalin solution once in a while.
