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.”
