Cooking ham in an oven with oven cleaner If a ham was cooked for 20 mins in an oven before realising that there was a layer of oven cleaner in the oven, is the meat safe to eat?
I'm not sure what kind of cleaner you used, but either way, the heat changes the molecular structure of the cleaner used and 'gases' it, allowing it to permeate into your food.  It is a shame, but throw it away.
