Check your grill brushes!!
I've heard some horrible stories about brush bristles attaching to food, getting swallowed, and wreaking havoc on the digestive track. I've noticed my brush is getting a little old and has left behind a few bristles on the grid the last few cooks. Just wanted to caution everyone to check your grid for bristles left behind. I think I may switch to a scouring pad type brush this time around.
