New Yorkers ordering from Mikado Poke on Uber Eats last April did not know that the kitchen where their ahi tuna and salmon bowls were being made had been cited for mice and flies.

That’s because Mikado Poke is among a growing category of virtual restaurants that operate solely online through sites like Uber Eats, Grubhub and Postmates — where their health ratings are not displayed.

The unappetizing issue was highlighted Thursday at a City Council hearing on delivery-only food operations popularized by the likes of Cloud Kitchens, a so-called ghost kitchen backed by ex-Uber CEO Travis Kalanick.

“My concern [is] that New Yorkers may not be aware that they are purchasing food from a place that is not up to their standards,” City Council member Mark Gjonaj, chair of the small business committee, said at the hearing. “Their health could be in jeopardy.”

Gjonaj said Mikado Poke is one of six online-only menus — including New Mikado Sushi — that prepare its food out of the kitchen of Mikado Bistro, a 525 6th Avenue restaurant that received a “C” health rating in April.

The NYC Health Department issued the “C” rating amid “evidence of mice or live mice present in facility’s food,” and the presence of “filth flies,” records show.

Mikado Bistro partner Ray Ali points out that the eatery has since earned an “A” rating after fixing the problems cited by the Health Department in April. “We are a small business that is trying to feed as many people as we can with the food that we have,” Ali said of the six online-only menus his eatery has developed at the advice of Uber Eats.

Currently, consumers who want to know the letter grade of a ghost kitchen have to look it up on the health department’s website.

“Alarm bells should be ringing,” Gjonaj exclaimed at Thursday’s hearing during the testimony of deputy health commissioner Corinne Schiff, who conceded that her agency was not as “transparent” as it could be about letter grades for virtual restaurants and ghost kitchens.

The council’s committee on small business is now weighing whether to require all restaurant listings to disclose a letter grade from the health department, including those found on apps like Grubhub, Seamless, Doordash and Uber Eats.

“I don’t know why letter grades would not appear on these apps,” Gjonaj told The Post.

The council is also looking at how the burgeoning industry could hurt existing bricks-and-mortar restaurants that currently have to display their health ratings for all to see.

“I feel like these third- party operators come in and build their business on our back,” Jeff Bank of Alicart Restaurant Group, which owns Carmine’s, testified. “We shouldn’t fall for these cloud kitchens.”
