So quick update.

She only v* the once, but went to bed early. She felt normal the next day which made us think it was likely just the leftover chicken didn't agree with her (weak stomach - she gets sick a lot).

No one else has gotten even remotely ill and it's been two days. Her boyfriend, who basically lives here, hasn't gotten sick either. I'll still be a little cautious but I'm feeling pretty good about it right now.
