Seems like I've had this happen several times over past few years..after eating something, I get a flu/cold-like symptoms.

I just got out of a 24 hr. like fever/flu ..just shortly after I ate seafood paella that I had made for both of us. There was shrimp, mussels, clams and halibut chunks amongst the risotto plus abit of white wine. Everything was well-cooked and served hot.

'Course I cursed that perhaps my body was in overdrive with too much carbs to drive my sugar level up too fast.

Another year I ate an apple that I washed in advance ..and ended up with a sore throat for a few days.
