Ok, when I make yogurt, I leave it in a warm area for 24ish hours.
So, the other day I bought two containers of full fat, plain organic yogurt.
Somehow the bag got left in the car. We found one of them the following morning. I thought the other one was already in the refrigerator. Nope, I found the 2nd one that afternoon. So, one was in the car from 4 to about 10am the following morning and the other one was found around 3 that afternoon.
I stuck them both in the refrigerator and just opened them and they smell perfectly fine. I tasted it and it tastes fine. But, I understand that not all bacteria smell.
So, would you eat it? I keep going back to the fact that when making your own yogurt, it sits in a warm place for 24 hours. But, it was warm in the car. Probably in the 80s that day.
