    I was cooking bone broth according to HIP recipe. The recipe says to cook one hour under pressure, then open the cooker. Close, bring back to pressure, cook another hour.

    After one hour I did NOT open the pressure cooker. I forgot. I left it on the kitchen counter overnight.

    Is it safe to continue cooking or should I toss the contents? I’m guessing it might be safe — that the second hour of pressure would kill any germs — but not sure.

    Feedback, please :)

    You need to get rid of it, not safe, even within a closed pressure cooker, the air must enter in order to equalize pressure. Since pressure exits during a Natural Pressure Release (NPR) then air also enters the same way.

    The current brochure, “Keep Food Safe! Food Safety Basics,” on the U.S.D.A. Web site, says not to leave prepared foods in the bacterial growth zone for longer than two hours. And if it’s a 90-degree summer day, cut the two hours to one. Link here:

    When in doubt, throw it out…

    Hope this helps out.
