I stand to be corrected but I feel ASIC hardware is an industrial computing equipment which means using it to warm any thing food-like including Pizza will require heating them in exhaust air gotten from this mining device and might pose threat to health. On another thought dust caked on the heatsinks can generate unpleasant odors or deposit particles that could be lead to serious illnesses.
What kind of health do you think this matchine will bring? Cancer?
I think you are over thinking it. You see the image from the first page, that's a clean miner, there is no dust from the picture and even if there is any, I don't think the food are openly exposed to.yhr food. Pizza are kept inside the paper and hot sink is supply through the medium. If there is anything that will pose health threat to the Piza then it's going to be the paper and not the mining machine.
