As a former biologist, I had a serious question about the worst-case implications of eating food found on the street, as in what types of poisons would be likely and what their effects might be. From that, I could determine probable courses of treatment, including informing a hospital etc.
I got some up votes, and people seemed to enjoy the post, as that type of question, while serious, is part of my inquisitive, and often humorous nature.
However, the question mysteriously disappeared without notification (Or I missed it). Whence and why did this happen?
This question was asked sometime around early 2013
