I cooked steak for dinner last night. Unknowingly, I cooked the plastic pad from the packaging along with the steak. I discarded the burnt plastic pad and we ate the steak. I assumed, perhaps wrongly, that there were no health consequences. My girlfriend was up all night with horrendous stomach cramps, diarrhea, vomiting. I didn't have that. But today I am very spacy and mentally not all here. Have I accidentally poisoned my girlfriend and me? Please advise. THNX!
