据欧盟食品安全局（EFSA）消息，近日，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Monteban®G100（甲基盐霉素）作为鸭饲料添加剂的安全性和功效发表科学意见。
经过评估，FEEDAP小组得出结论，Monteban®G100作为鸭饲料添加剂在70mg/kg饲料的使用水平下不存在消费者安全问题，也不存在环境风险，但是没有足够的信息来确定添加剂的功效。
部分原文报道如下：
The use of Monteban®G100 at a maximum concentration of 70 mg/kg complete feed for ducks for fattening is safe for the consumer without applying a withdrawal period, provided the maximum residue limit （MRL） of 50 μg narasin/kg for all wet tissues would not be exceeded.Monteban®G100 is irritant to the eyes but not to the skin. It has the potential to induce skin sensitisation. The acute systemic toxicity following dermal application is low. Inhalation exposure would pose a risk to persons handling the additive. Narasin, when used as feed additive for ducks for fattening at 70 mg/kg feed, is not expected to pose a risk to the environment. The risk for sediment compartment cannot be assessed. Narasin is not considered to have a bioaccumulation potential. Insufficient data were provided to allow a conclusion on the efficacy of Monteban®G100 in ducks.
