That happened to me once, though only for a day.
I had tried three new foods that day: frog legs,
that red Vietnamese chili sauce that comes in the
bottle with the rooster on it, and pine nuts
from China (much cheaper than what I was used to
paying).

Very sick, with a rash. I've never eaten frog
legs again, and I've had maybe about three
tablespoons of that chili sauce -- only at
restaurants -- in the last 15 years. I didn't
eat any pine nuts for a long time, and I always
check to make sure they're not from China.

For a long time, I suspected that an agent used
for chemical sterilization of the production
equipment for the chili sauce was not properly
flushed before being used to process the product
caused the problem. But logically, the frog legs
should be the number one suspect. And you sure
can't rule out Chinese pine nuts, for example
maybe they were treated with a fungicide.
