Me? I'd head to the nearest consulate. Boil water, even if I had to scrounge a vessel. Boil everything I ate for ten minutes.

That kind of thing is where the PSK comes into it's own. You can hide it in a small first aid kit. If anyone asks about the Micra or Classic on your key chain, well, so long as you put it in your checked baggage, not many people are going to actually see it. If they look at the fire making supplies and the duct tape, just grin sheepishly and tell them you were a Boy Scout.

The sheepish grin is the best concealment I know..
