Wholesale food suppliers want the city’s anti-organized-crime agency to swim with the fishes.

Fishmongers and meat and produce purveyors say restaurants and their patrons will feel the pinch of pricier porterhouses and higher-cost haddock if the Business Integrity Commission’s proposal for a huge regulatory-fee hike goes through.

The mob-busting commission wants to increase registration fees for each wholesaler to $4,000 from $250. It also seeks to raise the cost of employee ID cards to $100 from $20 and double the price of background checks to $600.

“Would I have to charge more? Probably,” said Marc Sarrazin, president of DeBragga and Spitler, a Gansevoort Meat Market wholesaler.

“It’ll put us in a bad bind,” said Amy Rubenstein, owner of Peter Luger Steakhouse, where the signature porterhouse for two goes for $75.90.

The hikes would generate more than $1 million in wholesaler registration fees over three years.

But the commission believes they can afford it.

“These proposed fees will have a minimal economic impact as these entities are among the largest wholesale businesses in the City,” said the commission’s General Counsel Eric Dorsch.
