In accordance with Article 6 of Regulation (EC) No 396/2005, the evaluating Member State (EMS), Hungary, received an application from Dow AgroSciences Ltd to set a maximum residue level (MRL) for the active substance aminopyralid in maize. In order to accommodate for the intended uses of aminopyralid, Hungary proposed to raise the existing MRL from the limit of quantification of 0.01 mg/kg to 0.05 mg/kg. Hungary drafted an evaluation report in accordance with Article 8 of Regulation (EC) No 396/2005, which was submitted to the European Commission and forwarded to EFSA. According to EFSA, the data are sufficient to derive a MRL proposal of 0.05 mg/kg for the proposed uses on maize. Adequate analytical enforcement methods are available to control the residues of aminopyralid in the commodity under consideration. Based on the risk assessment results, EFSA concludes that the proposed uses of aminopyralid on maize will not result in a consumer exposure exceeding the toxicological reference values and therefore are unlikely to pose a consumer health risk.
