McDonald’s Mexico has vowed to prosecute the person who they say planted a mouse’s head in one of its patron’s hamburgers, causing authorities to shut down one of its restaurants near Mexico City.

The company said in a statement distributed via social media it will be hiring the best investigation firm to identify the person responsible. It condemned the incident as a “serious attack against the (restaurant’s) image”.

The statement says the Commission for Protection Against Sanitary Risk (Cofepris) confirmed the animal was not cooked with the hamburger and they would be pursuing criminal action.

The incident occurred on 9 November when a man complained he found a mouse’s head in his McDonald’s hamburger in the restaurant in Tlalnepantla, north of Mexico City.

The branch was closed for more than two weeks after the complaint. The investigation continues to determine if the rat-tainted burger was bought in that particular restaurant.
