Six food trucks that had been operating on Exchange Place in Jersey City were slammed with multiple violations and towed away late last week, said Jake Hudnut, the Jersey City municipal prosecutor and head of the city’s Quality of Life Task Force.

All six trucks were delinquent in paying parking tickets and had flaunted sanitation, health and traffic laws, Hudnut said. All of the food truck owners were issued summonses to appear in municipal court in early September, where they face fines of up to $2,500 per day and 90 days of community service, Hudnut said.

The six food trucks were impounded Thursday night, but five of the six have been released after paying their outstanding parking tickets, Hudnut said. The sixth will remained impounded until proper registration, license plates and insurance are presented, he said.

“We took this action on behalf of the health and safety of our residents,” Hudnut said. “The unsanitary conditions of these trucks were unsettling. We want to make sure our residents are eating healthy, well-prepared food.”

“If everyday, hard-working people have to obey traffic laws and pay their parking tickets, so do these businesses,” he said. “There is no room for special treatment toward businesses in quality-of-life enforcement.”

Among the list of violations, according to Hudnut:

All the trucks were all parked in a no-parking zone and had outstanding unpaid parking tickets ranging from $280 to $4,752.

One vehicle did not have a license plate, valid registration or insurance.

Two of the vehicles — Halal Food and Rolling Cones of Newark — didn’t have mobile food truck licenses.

All six trucks had excessive grease and food debris on food preparation surfaces and the floor, and several did not have the required food handling certifications.

The vehicles violated the city a local ordinance prohibiting the operation of food trucks within 100 feet of one another.

Food servers failed to wear the proper hair restraints and nets.

The vehicles violated sanitation ordinances requiring trash cans within 10 feet of their service windows.

Two of the food trucks did not have certifications for the safe storage and operation of their propane tanks and one stored containers of gasoline next to its propane tank.

The owners of Halal Food and Rolling Cones could not be reached for comment.

The inspection was conducted by Hudnut, police Sgt. David Calton and East District police officers, two parking enforcement supervisors, a health inspector, a sanitation inspector and a fire safety inspector, Hudnut said.
