It would scare me enough to know that they can find trace amounts of the plastic bag that carried my blood into the hotel.
I wonder if that same test could taste the cedar plank that my salmon was infused with, because I sure can't.
"The cedar plank is soaked in water, and then when set on top of a grill. The wood smoke caused by direct heat is infused in the salmon and creates a great flavor that pairs nicely with the Maple Syrup and Mustard Glaze"
