Maybe if the lid had been off it MIGHT have been a bit safer if your kitchen was on the cooler side too. With the lid on there was no way for the heat to escape. My kitchen stays very cool and if that happened to me, lid OFF, it MAY have been ok. However, I've had food poisening (from eating out, not at home) about 7 times and I wouldn't hesitate in throwing it out!!!!!
This is for your wife ONLY - next time have him eat a bowl or two - put your feet up but don't have an adult beverage as you will have to drive
