airlock went dry

Ok I left my wife "in charge" to rack my beer into the seconday as she had done once before to my raspberry requiem and it came out awesome. This time she did it just fine about a week ago to my second batch. Today i get home from a 2 wwek work hitch and found the airlock completely dry. I am going to estimate that it has been dry for about 2-3 days. What should I look for to see if anything bad got in there. Are there any tell tale signs or will it just taste bad or different from my last batch?
Thanx

It should be fine. It either evaporated of sucked in either will be ok as long as you didn't have bleach or something nasty in the air lock.
I would be a long shot that it suck ed in a contaminant from the air.

It will be fine. Drink and enjoy.

Yep, no worries.
