I'd toss it as well, and goodness knows I like cooking turkeys.
By the time meat smells bad, it has already gone bad for quite awhile (it spoils for awhile, bacteria growing, b4 it gets so bad you can smell it). And you haven't had food poisoning until you've had bad-poultry food poisoning. For the 20 bucks the turkey cost, it's just not worth it. It's better to wonder if you've tossed good meat than to be SURE you ate bad meat.
Sorry for your turkey loss! Welcome to the boards!
If you're afraid of butter, use cream. ~~ Julia Child
As you cook, you enjoy omniscience about food that no amount of label reading can match. Having retaken control of the meal from the food scientists, you know exactly what is in it. (Unless you start w/cream of mushroom soup, in which case all bets are off.) To reclaim control over one's food, to take it back from industry & science, is no small thing; indeed, in our time, cooking from scratch qualifies as subversive. ~~ Michael Pollan
