At night I put a plastic (it said in korean language but also said other of plastic, it was transparent and thin) with a seaweed (ready to eat snack) inside a rice cooker to be heated (not cooked) with rice. At the morning, the plastic melted and become not transparent, however I ate the rice and the seaweed.. What should I do? Is this dangerous? I did a vomit, but I m not sure if I take out all of the food inside my body T-Ta..
