2020年2月14日，應(yīng)歐盟委員會(huì)要求，歐盟動(dòng)物飼料添加劑和產(chǎn)品（FEEDAP）研究小組就烏洛托品（hexamethylene tetramine）對(duì)豬、家禽、牛、綿羊、山羊、兔子和馬的安全性發(fā)布科學(xué)意見。

　　經(jīng)過評(píng)估，由于缺乏對(duì)烏洛托品殘留物的定性和定量描述，專家小組無法就其對(duì)目標(biāo)物種的安全性做出結(jié)論。部分原文報(bào)道如下：

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） was asked to deliver a scientific opinion on hexamethylene tetramine （HMTA） for pigs, poultry, bovines, sheep, goats, rabbits and horses. In 2015, the FEEDAP Panel delivered an opinion on the safety and efficacy of HMTA. In that opinion, the Panel noted that the residues of HMTA in the silage amounted to about 5% of the inclusion level of 600 mg HMTA/kg fresh ensiling material. Since the HMTA residues in silage were analysed as formaldehyde, it was not possible to quantify the contribution of formaldehyde and HMTA to the residues. In the absence of a qualitative and quantitative characterisation of the residues, the Panel could not conclude on the safety of HMTA for the target species. based on the results of a new study in which HMTA was measured in silage, the concentration of HMTA dropped below the limit of quantification of 6 mg HMTA/kg silage, which corresponds to ~ 1% of the HMTA inclusion level in the fresh ensiling material. However, the formaldehyde concentration was not analysed in the silage. In the absence of a qualitative and quantitative characterisation of the residues, the Panel cannot conclude on the safety of HMTA for the target species.
