根據歐盟委員會第396/2005號法規第12章，歐盟食品安全局審查了二噻農的最大殘留限量。根據對現有數據的評估，提出了MRL提案，并進行了消費者風險評估。雖然沒有發現對消費者的明顯風險，但缺少監管框架要求的一些信息。特別要強調的是，代謝物1，4-萘醌的毒理學參考值僅是臨時的，有待對潛在致突變性做出結論。因此，消費者風險評估僅被認為是指示性的，EFSA提出的一些MRL建議仍需風險管理者進一步考慮。部分原文報道如下：

According to Article 12 of Regulation (EC) No 396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide dithianon. To assess the occurrence of dithianon residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Commission Regulation (EC) No 33/2008, the MRLs established by the Codex Alimentarius Commission as well as the European authorisations reported by Member States and the UK, including the supporting residues data. Given that a data gap as regards the magnitude of residues of the metabolites 1,4-naphthoquinone and phthalic acid was identified in the peer review for dithianon in light of confirmatory data, the toxicological profile of these metabolites was also assessed in the framework of the Article 12 MRL review. based on the assessment of the available data, MRL proposals were derived and a consumer risk assessment was carried out. Although no apparent risk to consumers was identified, some information required by the regulatory framework was missing. In particular, it is highlighted that the toxicological reference values derived for the metabolite 1,4-naphthoquinone are provisional only, pending a conclusion on the mutagenicity potential. Hence, the consumer risk assessment is considered indicative only and some MRL proposals derived by EFSA still require further consideration by risk managers.
