In a web search on how long cooked turkey lasts, the results were 3—4 days in the fridge in the first ~20 or so hits. Exceptionally, one deviant article said 5—7 days but I lost track of it.
I regret not vacuum sealing the meat, each piece individually. All was in a big zip lock. On day 1 and day 2 I opened it to pull out a piece, which was more opportunities for contamination. Some sites say there is only a 2 hour window of time to get it into the fridge after the initial cooking. In my case that was probably more like ~6 hours. So I guess I made plenty of mistakes.
I’d be quite happy to make soup with it. After re-roasting and boiling it, the foul odor is gone. I’m sure it would taste fine.
But some people seem convinced it cannot be salvaged by any process. If it has clostridium perfringens, even if I kill the bacteria in the recook, it would have an exotoxin that would survive any amount of cooking.
I really wish I could have easily tested or know from the odor whether clostridium perfringens was present. The odor could have come from a less dangerous bacteria but I guess it’d be a risky gamble.
