Best source of information for cooking chicken and anything in fact.
Have you used your APC much before? Have you experienced long heating times for the water? I frequently deal with large quantities (a dozen beef cheeks or chicken breasts or even several roasting joints) at the same time in a large cooler with no extended reheating requirements. Perhaps take a few temperature checks of the bath to ensure your unit is performing as it should.
If you refer to the Baldwin table, at 150F if your chicken breasts were only an inch thick when raw they were successfully pasteurised. It is highly recommended that chicken be cooked to pasteurisation.
The thing is, you are the one that has to feel comfortable serving your guests. If in doubt throw it out. You are the only one who experienced your cook.
With regard to a more active forum… Other than Facebook. Fora are considered ‘old school’ so it is always highly unlikely that you’ll get the rapid turn around time on a query that you seem to expect.
