A Pennsylvania woman is suing Chick-Fil-A over claims that a dead mouse was baked into a sandwich bun.

Multiple national news outlets are reporting Ellen Manfalouti says she found the rodent when she "felt something funny on the bottom of the bun" of her chicken sandwich last November.

The woman says she made the disgusting discovery after a co-worker brought her the sandwich from a Chick-Fil-A drive thru.

At first she believed it was just a burnt spot on the bread, but once she saw the whiskers and tail, she realized it was a rodent.

Lab tests by her legal team later confirmed that it was in fact a mouse or rat. Manfalouti is demanding over $50,000 in damages from the Philadelphia-area restaurant.
