NEW MARYLAND, N.B.—A New Brunswick man says he found a dead mouse at the bottom of his McDonald’s coffee and the fast-food chain says it is investigating his complaint.

Ron Morais of New Maryland says he ordered a medium black coffee Monday from a McDonald’s in nearby Fredericton on his way to work.

The 57-year-old says he didn’t notice anything unusual until he popped the lid off to enjoy the last few sips.

Morais says he saw a small mouse wedged in the bottom of the cup with what appeared to be rodent feces.

He says he has been speaking with McDonald’s and doesn’t want anything from the company besides an explanation.

A spokeswoman with McDonald’s says the company is investigating, but that a pest control company inspected the site and found no evidence of pest issues in the building.
