Several East-European countries have called on the EU to address the "double standards" used by food companies in selling different products under identical labels in the bloc's eastern and western regions. These countries include Romania, Bulgaria, Hungary and Slovakia:

As far as I know, food industry is highly regulated in most if not all EU countries (clear list of ingredients, explicit list of food additives, calories per 100g/serving etc.).
Question: Why did this issue escalate to EU Commission level? Isn't food legislation supposed to deal with this kind of issues?
