lettuce or orangepeppers I ate them both on 2 days in a row . Explosive diarrhea 1/2 to 2 hours after. Not willing to rate the rest of the pepper or more of the lettuce to figure which is the problem. I washed everything before eating! Head of lettuce and a hug orangepepper. I have cut in 4ths . I have1/2 left of the orangepepper and a lot of lettuce but not willing to eat either to find which one is the problem. 1/2 hr after eating I felt sick and diarrhea started it k ok a test 2 hrs after.
