bad tortillas ?

[Tuxedokitty]

I bought a package of tortillas. Their was a small area on the edge of them that was orange, powdery like. I tore off that part and used all but one of them. A week later, the one left in the package was completely orange and powdery, the entire side and the package had this residue on it from the tortilla. What is this stuff that developed on the tortilla ? Should I take it to the Dept of Health and Human Services ?
