2023年12月11日，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就Availa®Cr（DL‐蛋氨酸铬螯合物（chromium chelate of DL‐methionine））作为奶牛饲料添加剂的有效性发布科学意见。
由于当前申请中提供的新信息缺乏足够的证据，专家小组仍无法对Availa®Cr作为奶牛饲料添加剂的有效性得出结论。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of Availa®Cr (active compound: chromium chelate of dl-methionine) as a feed additive for dairy cows. In a previous opinion, the FEEDAP Panel concluded that Availa®Cr at a maximum recommended use level of 0.5 mg Cr(III) (8 mg Cr from Availa®Cr/cow per day) was safe for dairy cows and the consumers. Additionally, the FEEDAP Panel considered that the additives posed a risk to the user by inhalation, it was not irritant to skin and eyes, and it should be considered a skin sensitiser. The Panel could not conclude on the efficacy of the additive at the proposed conditions of use. Since the new information provided in the current application is lacking sufficient evidence, the FEEDAP Panel is still not in the position to conclude on the efficacy of chromium dl-methionine from Availa®Cr.
