McDonald's Mexico vows legal action against person who planted mouse head in hamburger

MEXICO CITY – McDonald’s Mexico says it will prosecute whoever planted a rodent’s head in one of its hamburgers, causing authorities to close down one of its restaurants near Mexico City.

A company statement says it will hire the best investigation firm to find the identity of the person responsible for what it calls “a serious attack against the (restaurant’s) image.”

The statement, distributed through social media this week, says government testing proved the mouse was not cooked with the hamburger.

The Federal Commission for Protection Against Sanitary Risks would not comment on the testing, but referred The Associated Press to media interviews by a commissioner who confirmed that no rodent meat was found.

A man complained Nov. 9 that he found a mouse’s head in his hamburger in the store in Tlalnepantla.
