This question already has an answer here:

I defrosted a package of unopened sealed ribs outside for an hour and a half because I was short on time. I did not think it would be a problem, but after reading all the different posts, I am a little concerned. The package was sealed, so are they okay to eat? i rinised them and salted them and they are in the oven...

  • 'outside' is likely affected by where you are, and when it is. I've defrosted frozen turkeys outside for Christmas ... but it was fridge-like temperatures at the time, with water (and some ice) for thermal mass. – Joe Jun 15 '15 at 10:33
  • You say that you read other posts, but you seem likely to have missed our main post about defrosting outside, which explains the exact time limits of the danger zone. – rumtscho Jun 15 '15 at 11:43

From the FDA: Food temperatures between 40 °F and 140 °F, are ideal for bacteria.This range of temperatures is often called the “Danger Zone.” Never leave food out of refrigeration over 2 hours. If the temperature is above 90°F, food should not be left out more than 1 hour.

That said, if your ribs were frozen to begin with, then it certainly took 'some time' to reach 40°F and was likely not in "the danger zone" for over an hour, and 'should be' safe.
