'I am having a huge problem. I run a pizzeria, and we have gotten a warning from the Board of Health saying that pizza is not allowed to be used off of the slice display.'This, of course, has to do with the fact that the cheese cannot be left between 40Â°F and 140Â°F and then reheated. No matter how hot the oven is, it is still a violation according to the Board of Health.'My question is, how do i comply with their regulations and still produce a quality product?'
