Cheese Burger got miff on it

We wont to buy food from MacDonald's, went home, we opened the bag with food and as soon as my wife wanted to eat her burger, she saw something on the bottom of the burger.<br> <br> We checked carefully and saw that it was miff, the other cheeseburger had the same on.<br> <br> What would have happened if my wife ate that food, she is pregnant and would have gotten food poisoning.<br> Ho can a place sell food that is like that?<br> <br> I will never buy anything from any MacDonald's anymore, what happens back there in the kitchen?<br> <br> This needs to be taken up, and I want action taken.<br> I tried phoning the branch, but they keep on putting the phone down on me.<br> <br> Please provide me with feedback, I have photos of this and will try to attach it.<br> <br> Please contact me for the photos.<br> <br>
