You have to report this right away. When he bit into it did he know? Where you watching him eat? If he ate the whole thing and didn't know then how do you know?
You really have to nip food problems in the bud as they happen. Go to the resturant right away and don't wait until the next day. If he gets sick go to the hospital for food poisoning.
The longer you wait the more time, the more people will not take you seriously because you didn't take the problem seriously.
You can file a complaint with Wendy's on the Franchise level and then on a corporate level but unless you have some proof all you are going to get is a sorry letter and a few free food coupons.
If he gets food poisoning and they can prove medically or phyisically that it was wendy's then you can sue for medical bills and such.
I'm sorry your son had this happen but you need to take action and responsibility for what your child eats. I hope this turns out well.
