Anvisa稱，鑒于該分類，其將遵照2002法令第4074號的決議，著手分析該活性成分。該法令規(guī)定，當(dāng)存在風(fēng)險(xiǎn)依據(jù)時(shí)，應(yīng)推進(jìn)登記的農(nóng)化產(chǎn)品、其組份以及相關(guān)項(xiàng)的再次評估，及當(dāng)國際組織提出警告時(shí)，不再鼓勵使用登記的產(chǎn)品。
然而，Anvisa強(qiáng)調(diào)，“國際癌癥研究協(xié)會在該雜志中僅是提到了農(nóng)化產(chǎn)品的致癌性分類，有必要等到每一活性成分專論的公開發(fā)表，這樣可以對研究細(xì)節(jié)及分類進(jìn)行再次評估?！盇nvisa進(jìn)行毒性評估時(shí)應(yīng)遵照以下行政程序：通過聯(lián)合董事會決議發(fā)布活性成分再次評估的動機(jī)；介紹評估農(nóng)化產(chǎn)品的毒性研究；分析數(shù)據(jù)和發(fā)表的科學(xué)研究；與毒性科技領(lǐng)域公認(rèn)的研究機(jī)構(gòu)合作；發(fā)表供公眾評議的技術(shù)說明書；提高公眾評議的貢獻(xiàn)度；Anvisa工作人員組成再次評估委員會，這些人員來自巴西農(nóng)業(yè)、牧業(yè)與供應(yīng)部及巴西環(huán)境與自然資源研究所的代表；形成評估毒性的總結(jié)性技術(shù)說明書及CBR發(fā)表最終的再次評估結(jié)果。
