Modification of the existing maximum residue levels for 1,4-dimethylnaphthalene in potatoes

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Dormfresh limited submitted a request to the competent national authority in the Netherlands to modify the existing maximum residue level (MRL) for the active substance 1,4-dimethylnaphthalene in potatoes. The data submitted in support of the request were found to be sufficient to derive an MRL proposal. Adequate analytical methods for enforcement are available to control the residues of 1,4-dimethylnaphthalene in potatoes and residues of 1,4-dimethylnaphthalene, M23 and M23 conjugates in animal matrices. The data gaps identified during the MRL review relevant to the identity of metabolites found at significant levels in the processing studies and the analytical methods for enforcement in animal matrices were considered satisfactorily addressed. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of 1,4-dimethylnaphthalene according to the reported agricultural practice is unlikely to present a risk to consumer health.
