New York City health officials are expected today to require local units of restaurant chains to flag menu items containing more than 2,300 milligrams of salt.
The obligation would fall on branches of chains with at least 15 units nationwide, according to an Associated Press story. The article indicated that the warning would likely be a salt-shaker icon and would appear next to an item exceeding the sodium threshold, which is the equivalent of a teaspoon of salt.
New York has been the point of origin for a number of disclosure requirements later imposed on restaurants from coast to coast. It was the first jurisdiction to require chain restaurants to post calorie counts and the model for trans-fat bans that later became commonplace.
