The Chicago Department of Public Health closed the Quiznos sandwich shop at 1809 N. Harlem, after inspectors found sewage backing up from two drains in the food preparation area.

CDPH was alerted to the situation by a motorist who called 311 last night to allege that Quiznos’ staff was disposing of the sewage by shoveling it out their back door and into an alley. No evidence of that activity was found by CDPH inspectors today.

Quiznos will remain closed until its management has corrected the violation and passed re-inspection.

Representatives of the Quiznos franchise will have to explain themselves at an administrative hearing on April 17 and pay a fine expected to total $750.

Chicagoans who believe that a sandwich shop or other food establishment is operating in an unsafe manner are encouraged to dial 311 and report it.
