2019年5月27日，欧盟食品安全局（EFSA）发布消息称，拟修订土豆和小麦等食品中乙膦/膦酸（fosetyl/phosphonic acid）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 和De Sangosse SAS提交了该修订申请。根据风险评估结果，EFSA得出结论，摄入使用膦酸钾产生的残留物不太可能对消费者构成风险。
部分原文报道如下：
In accordance with Article 6 of Regulation （EC） No 396/2005, the applicants Luxembourg Industries （Pamol） Ltd and De Sangosse SAS submitted a request to the competent national authority in France to modify the existing maximum residue level （MRL） for fosetyl/phosphonic acid related to the use of potassium phosphonates on potatoes, wheat and some animal commodities. The data submitted in support of the request were found to be sufficient to derive MRL proposals for the crops under assessments and for animal commodities. Adequate analytical methods for enforcement are available to control the residues of phosphonic acid on the commodities under consideration at the validated limit of quantification （LOQ） of 0.01 mg/kg for high water‐ and dry matrices and at LOQ of 0.1 mg/kg in high acid matrices and in animal matrices and eggs at the validated LOQ of 0.05 mg/kg and in milk at the validated LOQ of 0.01 mg/kg. based on the risk assessment results, EFSA concluded that the intake of residues resulting from the use of potassium phosphonates according to the reported agricultural practices is unlikely to present a risk to consumers.
