In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant BASF SE submitted a request to the competent national authority in the Netherlands to modify the existing maximum residue levels (MRLs) for fosetyl/phosphonic acid (fosetyl-Al (sum of fosetyl, phosphonic acid and their salts, expressed as fosetyl)) in chards/beet leaves and honey. The data submitted in support of the request were found to be sufficient to derive MRL proposals for the commodities under assessment. Adequate analytical methods for enforcement are available to control the residues of fosetyl and phosphonic acid in chards/beet leaves and honey. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of phosphonic acid residues resulting in chard/beet leaves and honey from the use of potassium phosphonates according to the reported agricultural practice is unlikely to present a risk to consumer health.
