A famed Brooklyn pizzeria might be a slice of heaven, but it’s got one helluva bad health record.

Often called the city’s best slice joint, Di Fara Pizzeria on Avenue J in Midwood remained closed yesterday after being shut down Nov. 16 and deemed a “health hazard” by inspectors who found mouse droppings throughout its kitchen, among a slew of other sanitation issues.

Run by pizza maestro Dom DeMarco for nearly five decades and known for its long lines, Di Fara was previously shuttered by the Health Department in 2007. It has historically fared poorly in Health Department inspections, scoring 67 points Nov. 16 — more than double a failing grade.

Di Fara’s Facebook page blamed the closing on “personal matters,” and later said it’s “just a glitch in some paperwork bureaucracy with the [city’s] new grading system.”
