Occasionally I'll find a hair in my food. If I find one in say a restaurant, I won't eat my food, but I can't just throw out an entire platter of food if at home where my own grandma worked hard to cook it for me. In that case, I'll generally pick the hair out and continue eating (at least in that case I know where the hair has been).
If a hair falls into food in preparation, is the food still safe to serve/eat once the hair is removed? What are the potential hazards of serving food with a hair still in it?
