New harmonised rules concerning Maximum Residue Levels (MRLs) for pesticides took effect in the European Union on 1 September 2008. The new rules, contained in Regulation (EC) No 396/2005, harmonise the MRL rules of all 27 Member States and provide for a common EU assessment of pesticides. The new rules cover approximately 1,100 pesticides used in connection with agriculture inside or outside the European Union. They also identify specific MRLs for over 300 agricultural products as well as certain processed food products. The MRLs prescribed in the new rules also account for different sensitivities among certain consumers, e.g., babies and children.
