The Food Standards Agency is reportedly in talks with fast food chains and restaurants about adopting traffic light labelling on menus.

It has already held talks with McDonald's and caterer Compass Group to find out how the scheme could be introduced, according to reports in the Daily Telegraph.

“The FSA has begun talks behind closed doors to determine how they might introduce nutritional information to food that is bought for consumption outside the home,” an industry source told the paper.

“After the supermarkets, the next big win for the FSA is the big restaurant chains and contract caterers,” the source added. “For you local fish and chip shop, labelling would likely be a step too far.”

Front-of-pack nutritional labelling has split the food industry with companies such as Sainsbury's adopting the FSA's preferred traffic lights scheme but others such as Tesco preferring Guideline Daily Amount labelling.
