I remember reading about two siblings who became sick, they had to be hospitalized and while they were in the hospital their parents gave them ice cream as a treat, but soon after their condition worsened. They later found out the reason they were hospitalized was because the ice cream was contaminated with e.coli and while in the hospital the ice cream, same brand, they were given was also contaminated. Even worse was the siblings, who survived, had a rare genetic trait that was affected when they were infected with the e.coli and now they have lifelong, permanent disability due to that freak occurrence. This happened in the US, the mid-west I think and the result was diabetes or some sensitivity to drugs, I forget and can't find the article.
