JAPANESE MAYO: Is it man made?

Soooo-
I have a very sensitive stomach.
One time, my friend Franz dragged me into some Times Square porno shop and when he
taunted me with a "gaping anus" gem from the 5 dollar bin, I threw up all over my shoes.
That said, you can only imagine how easy it might be for me to get skeeved out over food.
My current complaint:
Japanese Mayo.
I love sushi. I love all Japanese fare...
well, that is except for ANYTHING THAT IS DRIZZLED/COVERED WITH/TOUCHED BY
"Kewpie Mayonnaise".
They drip this crap onto my sushi... and it's thick, watery and white.
I don't think I'm being irrational when I look at the white goop, see the sushi guy smiling and get sick to my stomach.
I mean, how can I ever REALLY know that it's "mayo" and not "man-o"?
I've just been fighting nauseousness over the thought all day.

No spitting. No swallowing. I'd just rather not ever let it get into my mouth.
