2021年11月10日，欧盟食品安全局（EFSA）发布消息称，拟修订乙膦/膦酸（fosetyl/phosphonic acid）在柑橘类水果中的最大残留限量。

根据欧盟条例（EC）No 396/2005第6章的规定，Luxembourg Industries （Pamol） Ltd 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膦酸钾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 Luxembourg Industries (Pamol) Ltd submitted a request to the competent national authority in Spain 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 citrus fruits. Adequate analytical methods for enforcement are available to control the residues of potassium phosphonates according to the existing and proposed residue definitions for enforcement in the commodities under consideration. Since EFSA raised concerns regarding the independence of some of the residue trials submitted in support of the MRL application, EFSA presented three options of MRL proposals for further risk management consideration. based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of potassium phosphonates on citrus crops according to the reported agricultural practices is unlikely to present a risk to consumer health.
