I recently witnessed a different kind of food safety hazard that probably occurs more often than is ever mentioned.
I kicked off last weekend with some classmates — drinks were flowing and the food was disappearing as fast as it could be cooked. Since everyone seemed to be hungry, plates were of no need. As I stood there eating my food I couldn’t help but notice what was going on just across my shoulder. One gentleman had found out how quickly selected beverages run through the body. He had made his way to the fence to relieve himself (since using a toilet would be way to civilized) and decided to place his uneaten hot dog in his mouth in order to free up his hands for other uses. After the job was done, he found it perfectly normal to take the hot dog back out of his mouth and continue eating his dinner

Probably not much of a risk for others, but certainly a yuck factor.
