Specializes in Internal Medicine

Runner beans: In Europe toxicity has been reported (not in the US) Usually signs appear within 1-8 hours, w/ nausea vomiting /diarrhea. Though you may not have had side effects at one time it does not mean it may not occur if you ate them raw/ undercooked again. Please cook thoroughly about 10 minutes. http://chemistry.about.com/b/2014/02/05/hemagglutinin-and-food-poisoning-from-beans.htm
