2023年8月14日，歐盟食品安全局（EFSA）發(fā)布消息稱，擬修訂苯醚甲環(huán)唑（difenoconazole）在小麥和黑麥中的最大殘留限量。
根據(jù)歐盟條例（EC）No 396/2005第6章的規(guī)定，Syngenta Crop Protection AG提交了該修訂申請。經(jīng)過評估，歐盟食品安全局得出結(jié)論，從飲食中攝入小麥和黑麥中苯醚甲環(huán)唑殘留物的量很低，并指出預(yù)期用途對動物產(chǎn)品中殘留物和消費(fèi)者接觸的影響無法得到適當(dāng)解決。部分原文報(bào)道如下：
In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Syngenta Crop Protection AG submitted an application to the competent national authority in Germany (evaluating Member State, EMS) to modify the existing maximum residue levels (MRLs) for the active substance difenoconazole in wheat and rye grain. The data submitted in support of the request were found sufficient to derive MRL proposals for wheat and rye grain. Adequate analytical methods for enforcement are available to control the residues of difenoconazole in plant matrices under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. The submitted data indicate no need to modify the EU MRLs in animal commodities for the existing enforcement residue definition. EFSA concluded that the dietary exposure to difenoconazole residues from the intake of wheat and rye grain is low, noting that the impact of intended uses on the residues in animal commodities and the consumer exposure could not be properly addressed. Overall, the present risk assessment confirms a very narrow margin of safety for the overall chronic exposure and is considered provisional, pending the submission of confirmatory data on possible preferential metabolism/degradation of the four stereo isomers of difenoconazole in plants and animals and the impact of isomerisation on the toxicity of difenoconazole. The assessment is also affected by uncertainties related to the toxicological profile of animal metabolite CGA205375 and, additionally, it does not take into consideration triazole derivative metabolites (TDMs).
