You should look at the potential for the materials used in the chemistry labs to sorb into the lab bench tops. I had a material containing 35S sorb into a black lab bench top that we could never remove. It stayed hot regardless of how much or what we scrubbed it with.

Thank you all for your responses.  I guess I should add a bit more detail.  This "flip" of the lab space would occur every semester (so one semester would have chemicals, the other food).  This food would be for consumption by the students preparing it.

Those of you saying that it could be "decontaminated" to the point that it would be suitable for this type of use, I assume you mean scrubbing down every surface and then taking representative samples from around the room to test for every hazardous material ever used in the room?

Would any of you or your organizations permit food in a laboratory space that does not currently house chemicals, nor have current work going on with chemicals?  Specifically, would you permit a class involving food preparation to occur in a lab space that the previous semester was used for a freshman level general chemistry class, even if the area were "cleaned" and all chemicals removed?
