NEW YORK CITY – A Manhattan judge upheld a city requirement that some restaurants provide warning labels for salty foods, the New York Times reports. The city’s Board of Health approved the measure in September, but a lawsuit filed by the National Restaurant Association halted the Dec. 1 implementation.

With a new start date of March 1, the ordinance mandates that restaurants with 15 or more U.S. locations post a saltshaker image next to menu items with at least 2,300 milligrams of sodium. A few chains with New York locations, including Applebee’s Regal Entertainment Group and Subway, have added the salt warnings.

The National Restaurant Association will appeal the judge’s decision. It also intends to seek “emergency interim relief” from the Appellate Division of the New York courts that would stay enforcement of the law pending that court’s decision.

“We believe [the] decision by the court to uphold this arbitrary, onerous and costly mandate is a blow to small business owners and undoes the very uniformity we worked for in advocating for a national federal menu-labeling standard,” said Angelo Amador, the NRA’s regulatory counsel, in a statement.
