My bet is that it's OK but then I'm not eating it. I had my turkey in the mini fridge for a few days and got basically the same type reading as far as the liquid temp.
It's kind of a tough fridge to get dialed in. So, I put the probe in the cavity of the bird, touching the rib bones and it was much cooler than the surrounding liquid and in the safe zone.
I did brine that bird for 24 hours as the salt helps. Long story short, 5 hours in the BGE and finishing temp of 165, everything was good to go and no ill effects from anyone.
