2023年5月30日，欧盟食品安全局（EFSA ）发布消息称，拟修订磷酸钾（potassium phosphonates）在韭葱和大葱中的最大残留限量。
根据欧盟条例（EC）No 396/2005第6章的规定，BASF Agro B.V. Arnhem (NL) Freienbach Branch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，长期摄入因使用磷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 BASF Agro B.V. Arnhem (NL) Freienbach Branch submitted a request to the competent national authority in the Netherlands to modify the existing maximum residue levels (MRLs) for the active substance potassium phosphonates in leeks and spring onions/green onions/Welsh onions. 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 potassium phosphonates in accordance with the proposed residue definition ‘phosphonic acid and its salts expressed as phosphonic acid’ on the commodities under consideration. based on the risk assessment results and assuming that the exiting MRLs will be amended as proposed by EFSA in previous outputs, EFSA concluded that the long-term intake of residues resulting from the use of potassium phosphonates according to the reported agricultural practices is unlikely to present a risk to consumer health. Considering the toxicological profile of the active substance, a short-term dietary risk assessment was not required. The risk assessment shall be regarded as indicative because some MRL proposals derived by EFSA in the framework of the MRL review according to Articles 12 and 43 of Regulation (EC) No 396/2005 require further consideration by risk managers.
