I had eat chicken lolipop before a week. After eating, I found that the colour of the food was not natural, maybe it had artificial colours. Some of the colour stick to my hands. I washed my hands with handwash 4 to 5 time, still the colour was there. I am in great worry about my alimentary canal. Because the colour of my stool was similar to the colour added to the food. A week passed after that, still my stool colour is not normal. Will the colour which was added to the food stick to the intestine forever. Will it cause cancer?
