The New York Department of Health and Mental Hygiene says on its website that an April 9 restaurant inspection at the Metropolitan Opera found "evidence of mice or live mice present in facility’s food and/or nonfood areas."

The nation’s largest musical organization also was cited for "food not protected from potential source of contamination during storage, preparation, transportation, display or service."

The department did not issue a notice of violation against the Met because the inspection found 13 violation points — below the average of 15 for New York City restaurants.
