Hard blue plastic inside of Econo Foods Chicken Burgers.

I am absolutely disgusted with the product I have received. I cooked the Econo Food's Chicken Burger for my 5 year old nephew and myself. While eating the burger (on its own as I'm doing a carnivorous diet) I bite into something hard. It was a hard piece of blue plastic in the middle of the burger. I immediately stopped my nephew from eating the rest of his burger. Who knows what would have happened if he had got the burger I got instead.
