欧盟评估生育酚磷酸酯混合物作为所有动物饲料添加剂的安全性和有效性

 

　　经过评估，专家小组无法就添加剂对环境、目标物种和消费者的安全性做出结论，也无法就该添加剂对所有动物物种的功效做出结论。部分原文报道如下：

 

　　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 the safety and efficacy of tocopheryl phosphate mixture (TPM) as nutritional feed additive for all animal species. The additive has not been authorised for use in animal nutrition. TPM is produced by chemical synthesis and is a mixture of two different phosphorylated tocopheryl compounds in approximate 2:1 weight ratio: all-rac-α-tocopheryl di-hydrogen phosphate (TP) and all-rac-di-α-tocopheryl hydrogen phosphate (T2P). It is intended to be used as nutritional additive (as a source of vitamin E) in feed for all animal species and categories. Considering the limited information on the ADMER for the components of the additive and the uncertainties on the potential aneugenicity and clastogenicity of the additive, the Panel cannot conclude on the safety of the additive for the target species and for the consumer. TPM is not a skin irritant nor a skin sensitiser but should be considered irritant to the eyes and the upper respiratory tract. Owing to the uncertainty on the potential aneugenicity and clastogenicity of the additive, it is not possible to conclude on safety for the user. The FEEDAP Panel cannot conclude on the safety of TPM for the environment due to lack of data on environmental impact of T2P. TPM is a bioavailable source of α-tocopherol. The data available, however, do not allow the Panel to establish the relative bioequivalence of TPM as vitamin E. Therefore, the Panel is not in the position to conclude on the efficacy of TPM for all animal species.
