Shorting a lipo=destruction?

OK, about a half hour ago, i accidentally shorted a cell for around 1-2 seconds I checked the voltage, and it seems to be holding voltage steady, and the pack isn't heating up (or puffing).
Does shorting the cell guarantee a cell failure in the near future, or is there a fair chance the cell will be fine?
Also, other then waiting, is there any way to ensure the cell is safe?

BTW this is a new cell if that matters.
