Popped an airlock, ramifications?

Found last night that a carboy of Reisling well past the secondary lost its
airlock.  Don't know if it was the kids, the dog or what.  Potential time
exposed is 1 day to worse case 6 days.  (The last racking.)  Carboy was
topped off well into the neck.  I immediately inspected, no visable
contamination of bugs or junk.  Hit with a dose of SO2 and capped it.

Can I do anything else?
