Two tractor-trailers picked up some 80,000 pounds of beef from a slaughterhouse in northeastern Tennessee and then vanished, authorities said this week.

They can’t figure out where the beef is, but a fake trucking company made off with enough meat to make about 320,000 quarter-pounders, the Grainger County Sheriff’s Office said.

The meat was taken from Southeastern Provision, a processing plant in Bean Station, Tennessee, a town nearly 50 miles northeast of Knoxville. It was not clear when exactly the beef was stolen, but the investigation began Tuesday.

At least two of the customers of the meat processing plant reported that they had not received their shipments, officials said.

The two approximately 40,000-pound shipments were to be sent to customers in Kentucky and Michigan, the sheriff’s office said.

The shipments, valued at $350,000, remained missing as of Friday.

Last month, in another headline-grabbing food plunder, 100,000 organic eggs were taken from a distribution trailer in Pennsylvania.
