Is food with hair in it (or food which had hair in it) safe to eat? 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?

Hair is a protein mostly keratin


  Keratin refers to a family of fibrous structural proteins. Keratin is the key of structural material making up the outer layer of human skin. It is also the key structural component of hair and nails.


There's nothing special about it as a protein, so as long as it doesn't wrap around your tonsils and get stuck in your throat, or contain dyes, hairspray etc. it's safe to eat.
However, the long stringy nature of the stuff can cause problems if you eat too much of it.
