How long can sealed packaged yogurt be out of refrigerator before it goes bad?

Answer 1

Some people would consider the risk of bacteria in food being left out too great to risk eating after one hour. Open Yogurt will separate after 4 hours, and will spoil after 12 hrs at room temp.

Yogurt, though, is produced with bacteria, changing its spoilage dynamic.

If it is still sealed, for example, uncontaminated yogurt has a much longer safe longevity*. However even then you are risking at least indigestion from the higher concentration of bacteria.

If it separates in the container, however, that is a sign it has probably been contaminated, or was not an ideal bacterial mix to begin, and should not be eaten regardless how long it was at room temp.

*Personal experience having eaten yogurt that at different occasions was; 6 months expired, left in a hot car for 1 day, and left in a backpack at room temperature for 2 days; with the only side effects being a change of texture with the hot car, and indigestion from the backpack yogurt. Room temperature is possibly the least safe of the three, based on that.

Answer 2

Yogurt doesn't last that long but it does in the fridge! Even if it has expired by 2 days you can still eat it(if it's been in the fridge all the time)! Yogurt usually lasts between 1-2 weeks.

as long as the expiration date says

Answer 3

I wondered this the other day too when I was looking at a yogurt that was 2 weeks past the date. It says on the container that it is good for 1 week afterwards. I opened it and did not see anything growing; or smell anything bad; or taste anything bad, so I ate it. I'm still alive (obviously). I wouldn't push it too far past the date or make a habit out of it, but I have a hard time throwing away what looks like good food just because of a date stamp.

Answer 4

Bacteria can form on food left out of the refrigerator after an hour.

Answer 5

At least two days.
