According to Texas Food Establishment Rules (TFER), a Mobile Food Unit (MFU) is a vehicle mounted, self or otherwise propelled, self-contained food service operation, designed to be readily moveable (including, but not limited to catering trucks, trailers, push carts, and roadside vendors) and used to store, prepare, display, serve or sell food.
Mobile units must completely retain their mobility at all times. A Mobile Food Unit does not mean a stand or a booth.
A roadside food vendor and pushcart may be licensed as MFUs. These special provisions, along with TFER references, shall be met before operating.
