A new menu labeling ordinance goes into effect Monday for many Louisville restaurants.The ordinance was first proposed in July and only applies to restaurants that already have calorie counts for their menus available.“Any food service establishment that posts caloric or other nutritional information on its website—or through other communications methods—that they need to make that same information available to customers on site at the restaurant," says Department of Public Health and Wellness spokesman Dave Langdon.The rule does not apply to chains with more than 20 locations, as the Affordable Care Act already requires such establishments to disclose nutrition information.Public Health and Wellness officials will review an establishment’s website for nutritional information prior to its regular food inspection. Restaurants found in violation of the ordinance will have 14 days to come into compliance. After the 14 day period, they will be subject to a fine of $25 per day.
