2022年7月20日，欧盟食品安全局（EFSA）发布消息称，拟修订溴氰菊酯（deltamethrin）在玉米中的最大残留限量。
根据欧盟条例（EC）No 396/2005第6章的规定，Bayer SAS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溴氰菊酯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 Bayer SAS submitted a request to the competent national authority in Austria to modify the existing maximum residue level (MRL) for the active substance deltamethrin in maize/corn. The data submitted in support of the request were found to be sufficient to derive a MRL proposal for maize/corn. Adequate analytical methods for enforcement are available to control the residues of deltamethrin (cis-deltamethrin) in maize/corn under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg and in animal matrices at the validated LOQ of 0.01 mg/kg. based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of deltamethrin according to the reported agricultural practices is unlikely to present a risk to consumer health. The risk assessment shall be regarded as indicative and affected by non-standard uncertainties.
