I've got a whole chicken which is a couple of days past its sell-by date. It's vacuum packed, and when I bought it the plastic was flush against the meat. Now there are gas bubbles in there, and the plastic bulges out in places, but it's still sealed tight. I know that for canned food, a bulging lid can mean contamination. Has this fowl gone foul?
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
