Respiratory infection, coco husk safe

A snake with an RI passed away unfortunately recently, it would be a shame to waste alp
the coco husk I have as substrate, is the stuff reusable if I possibly bake it in the oven or something? Or do I just dump it?

Double bag it and put it in the trash. Reusing substrate in any situation isn't a good idea.

Never reuse the same bedding from a sick animal.
Any porous items from the cage that can't be sterilized should also be tossed.
