A judge has ruled certain New York City restaurants can be fined for not posting salt warnings for some food items on their menus.

State Supreme Court Justice Eileen Rakower ruled from the bench Wednesday allowing the city to enforce the first-of-its-kind rule.

It requires chain restaurants to put a salt-shaker icon on menu items that top the recommended daily limit of 2,300 milligrams of sodium. That’s about a teaspoon.

The National Restaurant Association sued in December to stop the rule. Restaurants can be fined up to $600 for failing to post beginning March 1.

New York has faced lawsuits over other healthy-eating measures it’s pioneered. Courts struck down a size limit on sugary drinks but upheld a requirement for chain eateries to post calorie counts on menus.
