Why is it sanitary to use the same spatula to cook hamburger from raw to cooked?

When you place the burger on the grill, you usually use your hands. Then when you do the first flip, the underside of the burger is cooked. So the spatula is actually touching cooked meat on the first flip. Hope this helps. As for the girl that was trying to compare it with bacon... The bacon I cook is actually smoked when I buy it, so it is actually cooked before it hits your pan. Have a nice day.
