Giardia is nasty business. The most notable symptom is what is clinically referred to as, “explosive diarrhea.” It’s not pretty.

It’s one of the major reasons that government and health officials urge you to not drink the water while traveling in places like, oh lets say, Ethiopia.

In the entire time I spent Ethiopia, eating on the street, drinking non-bottled water regularly, I didn’t get it once.

I’ve gotten twice in the United States from Ethiopian food.
