2023年8月7日，欧盟食品安全局（EFSA）发布消息称，拟修订1,4-二甲基萘（1,4-dimethylnaphthalene）在马铃薯中的最大残留限量。
根据欧盟条例（EC）No 396/2005第6章的规定，Dormfresh limited提交了该修订申请。经过评估，欧盟食品安全局得出结论，根据所报道的农业实践，短期和长期摄入因使用1,4-二甲基萘而产生的残留物不太可能对消费者健康构成风险。部分原文报道如下：
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.
