It’s not. Not at all. If it has a space in your freezer, the fastest you will put in in the fridge the longer it will last, and will be more sanitary.

In room temp, germs multiple on your food in a rate of doubling every 20 min (exponential growth)

In fridge its at least 8 hours I believe, for every doubling themselves, and freezer its a day and a half
