L 335/14 Official Journal of the European Union 14.12.2013 COMMISSION IMPLEMENTING REGULATION (EU) No 1335/2013 of 13 December 2013 amending Implementing Regulation (EU) No 29/2012 on marketing standards for olive oil THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Council Regulation (EC) No 1234/2007 of 22 October 2007 establishing a common organisation of agri- cultural markets and on specific provisions for certain agri- cultural products (Single CMO Regulation) ('), and in particular Article 113(1)(a) and point (a) of the first paragraph of Article 121 in conjunction with Article 4 thereof, Whereas: (1) ~ Commission Implementing Regulation (EU) No 29/2012 (%) lays down specific standards for retail-stage marketing of olive oils and olive-residue oils. (2)  Producers, traders and consumers should be provided with marketing standards for olive oils which guarantee product quality and combat fraud effectively. To that end, specific provisions should be laid down to supplement Regulation (EU) No 1169/2011 of the European Parliament and of the Council () and to improve the effective monitoring of marketing standards. (3)  Numerous scientific studies have demonstrated that light and heat adversely affect the quality of olive oils. Specific () OJ L 299, 16.11.2007, p. 1. (?) Commission Implementing Regulation (EU) No 29/2012 of 13 January 2012 on marketing standards for olive oil (O] L 12, 14.1.2012, p. 14). Regulation (EU) No 1169/2011 of the European Parliament and of the Council of 25 October 2011 on the provision of food information to consumers, amending Regulations (EC) No 1924/2006 and (EC) No 1925/2006 of the European Parliament and of the Council, and repealing Commission Directive 87/250/EEC, Council Directive 90/496/EEC, Commission Directive 1999/10/EC, Directive 2000/13/EC of the European Parliament and of the Council, Commission Directives 2002/67[EC and 2008/5/EC and Commission Regulation (EC) No 608/2004 (O] L 304, 22.11.2011, p. 18). [ ~ storage conditions should therefore be clearly indicated on the label to ensure that the consumer is well-informed about the best conditions for preservation. (4 In order to help the consumer to select products, it is crucial that the mandatory particulars indicated on the label are easily readable. Rules should therefore be laid down on readability and the concentration of mandatory information within the main field of vision. (5 In order to enable the consumer to be sure that the product is fresh, the optional marking of the harvest year should only appear on the label when 100 % of the packaging contents come from that harvest. (6)  In the interests of simplification, it should be laid down that the labelling of food products preserved exclusively in olive oil is no longer required to state the percentage of oil added in relation to the total net weight of the foodstuff. (7) In order to ensure consistency between Commission Regulation (EEC) No 2568/91 (*) and Implementing Regulation (EU) No 29/2012, particularly as regards the tolerance for the result of checks, the relevant provision of that Implementing Regulation should be amended accordingly. (8)  Member States must carry out checks to ensure that the markings on the labels are correct and to ensure compliance with this Regulation. To that end, checks on the conformity of the product’s sale name with the contents of the container should be reinforced and further harmonised on the basis of risk analysis, as should corresponding penalties. This approach should also help to combat fraud by introducing minimum control requirements for all Member States and by stan- dardising the reports to be sent to the Commission.
