NO! Cooking does not render bad meat good or edible. This is always my biggest fear as a judge -- that somebody will go ahead and prepare tainted meat.
I've had several instances of bad meat in cryovac -- usually ribs. That's why I always save my receipts AND open all my meat (cryovac and local packaging) before I head for a contest or get ready for a big cook.
If it smells bad, please don't cook it
