How long can you keep jello OUT of the fridge?   Foods that are left out in room temperature for more than an hour can begin bacteria growth. Our stomach acids can kill some of these bacterias but not all and some can â¦make you very sick. Keep foods OUT of the danger zone- Above 45 degrees and Below 145 degrees. Between these temperatures bacteria lives and breeds on our foods. 2 people found this useful.
It's good for longer then an hour. They say that in the back of the directions because they want u to use more formula. It can be good for up to 3 hours. But if ur not sure then what I use is a formula jug and only poor what I think my little guy is going to eat. The formula jug in the fridge is good for 24 hours. I love it. Also making it a head of time brings down the bubbles in the formula.
