經(jīng)過(guò)評(píng)估，在沒(méi)有新數(shù)據(jù)的情況下，專家小組無(wú)法就添加劑對(duì)用戶的安全做出結(jié)論。專家小組認(rèn)為，先前關(guān)于功效的結(jié)論仍然有效。部分原文報(bào)道如下：

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of the authorisation of urea as nutritional feed additive. The additive is authorised for use in ruminants with functional rumen (3d1). The applicant provided evidence that the additive currently in the market complies with the existing conditions of authorisation and the production process has not been substantially modified. The FEEDAP Panel considers that there is no evidence to revise the conclusions reached in the previous assessment for the target species, consumer and for the environment when used as a source of non-protein nitrogen under current conditions of use, in ruminants with functional rumen. In the absence of new data, the FEEDAP Panel is not in the position to conclude on the user safety. The Panel retains that previously made conclusion on the efficacy remains valid.
