Burger King in the USA has taken legal action against a franchisee after serious reports of unsafe food practices emerged. Fritz Management, which owns 37 Burger King locations in Texas, is being sued by Burger King after a video emerged which reportedly showed rats and newborn mice taking up residence next to burger buns.

Burger King has accused Fritz Management of “exhibiting reckless disregard for the physical and mental well-being” of employees and the public and declared it in default of the franchise agreement. It claimed that the incident has “generated significant negative social media comments about the Burger King restaurant system.”

In response, Fritz Management CEO Guillermo Parales said he was “surprised” by the lawsuit and offered no further comment.
