Twist tie burn in microwave?
I thawed out some hamburger meat wrapped in plastic but didn't notice the twist tie that was on the bag it was in
It burned and melted a small bit of plastic wrap that was over the meat, I removed the effected part, is the rest still ok to use ?
Of course your hamburger is still ok to use. Most plastic wrap sold today is safe for microwave use, especially the newer plastics. I would not worry about it, but I would not routinely microwave plastic wrap unless the plastic wrap does not actually touch the food.
