My sympathy. I'm the same way anywhere with ripe corn or rice. I went down to visit family in rural Kentucky at the end of summer and immediately fell ill. I find allegra works best for me but even that failed me. The sinus infection I got in Florida probably came from staying in the mold infested apartment, and all the swimming you inevitably end up doing.

I have my fingers crossed that I'm not too allergic to anything in Korea.
