Can this hurt my baby?

Rebecca

Went to lunch with hubs. Got chinese food chicken with mashed potatoes. Couldn't finish ir there so I brought mine home.

Well I just reheated it and ate some of the rest of my mashed potatoes. There was a sour black freaking rotten potato mixed in! I thought potatoes tasted funny.

I am SO afraid (to the point of.crying) this can hurt my baby if I ate enough of it
