Putting the gag in Gaga

Lady Gaga’s parents are no hit with the city’s health inspectors.

Joanne Trattoria, the Upper West Side Italian joint owned by the pop princess’ mom and dad, got a barf-inducing “C” grade from the Department of Health for hygiene and cleanliness problems.

Joanne — owned by Joseph and Cynthia Germanotta — was hit with “critical” violations that included unwashed food-prep surfaces, no hand-washing facilities close to the kitchen and food placed in areas ripe for contamination.

The demerits totaled 42 points — well above the 0 to 13 points for an “A,” or the 14 to 27 for a “B.”

The restaurant was given two placards it could place in the front window — a “C” or a “grade pending.”

“We’re going to be taking it to court,” said Joanne general manager Travis Jones. “So, it’s bogus until November, when it’s finalized. We’re planning on disputing it.”
