In accordance with Article 6 of Regulation (EC) No 396/2005, the United Kingdom received an application from Dow AgroSciences Ltd. to modify the existing MRLs for aminopyralid in food derived from ruminants in order to account for residues which occur in these commodities when livestock is fed with grass treated with aminopyralid according to the authorized GAPs in the United States, Canada, Bolivia, Argentina and Brazil. The EMS proposed to raise the existing MRLs for aminopyralid in ruminant meat, fat, liver, kidney and milk. The metabolism of aminopyralid has been elucidated in lactating goats and poultry. Parent aminopyralid is proposed as residue definition for enforcement and risk assessment for all products of animal origin. The residue levels in the imported food of animal origin should reflect livestock exposure from the intake of all feed crops treated with aminopyralid in the country of origin. Since EFSA does not have a comprehensive overview of the feeding practices and the aminopyralid residues in feed available in these countries, it is more appropriate to calculate the dietary burden on an international level, using internationally agreed methodologies. Thus, livestock dietary burden calculated by the JMPR was used to estimate the potential carry-over of residues into food of animal origin. Data from feeding studies indicate that the existing EU MRLs have to be raised for ruminant meat, fat, kidney and liver. For milk, eggs, poultry and swine products no modification of the existing EU MRLs is required. Based on the risk assessment results, EFSA concludes that residues in food commodities of animal origin from the use of aminopyralid on grass in third countries and the resulting MRL proposals will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a public health concern.
