Short answer yes. Ingested jet fuel is apparently one of the most toxic and carcinogenic substances known. It seems like that is said about a lot of things nowadays, but there is no debate about the effects of jet fuel. I never thought much of it at the time, we kind of laughed about it counteracting the boat crud. I don't think it is so funny anymore.
But what are you going to do? You gotta drink something.
The funny thing is that Air BP, in its MSDS's only admits that it is a mild skin irritant....except in one small subsection that basically says that in California, Jet-A (and presumably JP-whatever) causes cancer in lab animals. Funny how that works. Next time I will close my mouth when topping the MD-500
