On friday at my job i was in the break room and i was gonna put a frozen pizza in the toaster over when a fellow co-worker of mine assisted me, she took the pizza out of the box with her bare hands and put it in the toaster oven, i turned it on to like 400 and cooked it for like 10 minutes maybe. I later noticed she had some cuts and stuff on her hads. If she had gotten some blood on the pizza and i ate it would there be any risk from something like this. Please answer.
