Articles 26 and 27 of Regulation No 882/2004 of the European Parliament and of the Council of 29 April 2004 on official controls performed to ensure the verification of compliance with feed and food law, animal health and animal welfare rules, as amended by Regulation (EU) No 652/2014 of the European Parliament and of the Council of 15 May 2014, must be interpreted as not precluding the imposition of a charge, such as that at issue in the main proceedings, on retail food outlets only, where the revenue from that charge is not used specifically to finance official controls that have been caused by, or that are for the benefit of, those chargeable persons.
