All three of my sons had salmonella poisoning after thanksgiving one year. One ended up having his appendix out because of the swelling in the nodes, etc. Lots of puking and diarrhea with this one. The health department called on us. None of the adults had it so I'm thinking it was the milk.
Yow, I hope that didn't sour them to the holiday. I know, easy to joke now :) I had food poisoning once and it is decidedly not funny at the time.
