Ok, small children and easily offended adults should stop reading this post right about now. When they say 'cross contamination' it really means 'raw chicken contamination', because there's no harm in putting the clean into the dirty, and because there's nothing else as dirty in the kitchen, including the just released from jail cook, than chicken. And the joke 'must be sprayed with bleach if contaminated with chicken' isn't a joke. They generally are washed down with a bleach solution before packaging so they don't smell like poo when you open the package. If the average person saw or smelled a chicken going into a processing plant they'd never eat the stuff again.
Yes, I eat chicken, but I wash the stuff and cook it to 165F, and treat it like it's leaking and dripping critters everywhere when it's raw...because it is.
Beef burger? I'll eat them rare.
