Event - I had a birthday party for my son 2 years ago and served crackers as part of the snack. A week later I found out those crackers had been recalled due to possible salmonella poisoning. I didn't have the cans still to check the batch. I thought about calling all the parents and letting them know, in case their kids got sick, but decided it might be better not to panic anyone since I didn't even know for sure if I had the bad batch.
Apology - Knowing what I know now about recalls and the dangers, I should have called them all. I guess it was my fear of being called a bad mom, even though there was no way I could have known. On the plus side, no one got sick.
