Dog help?!

My fiancé is making frozen chicken nuggets and dropped one on the floor accidentally and let my dog get to it before he could pick it up. So my dog just ate a frozen chicken nugget. Should I be heading to the emergency vet? Idk what to do. I don't let my dogs eat any meat ever let alone pre cooked frozen so I'm really freaking out!! Will she get worms? Something else? Please help if you can..
