欧盟评估枯草芽孢杆菌CGMCC 13326生产的维生素B2作为所有动物饲料添加剂的安全性和有效性

 

　　经过评估，专家小组认为使用枯草芽孢杆菌CGMCC 13326生产的维生素B2不会引起安全问题。当通过饲料施用时，被评估的添加剂在满足动物对维生素B2的需求方面是有效的。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) of EFSA was asked to deliver a scientific opinion on the safety and efficacy of vitamin B2 (riboflavin) produced by Bacillus subtilis CGMCC 13326 as a nutritional feed additive for all animal species. The additive is produced by a genetically modified production strain. Although the production strain harbours some genes coding for resistance to antimicrobials, viable cells and DNA of the production strain were not detected in the final product. Therefore, the use of B. subtilis CGMCC 13326 to produce vitamin B2 does not raise safety concerns. The use of riboflavin 80% produced by B. subtilis CGMCC 13326 in animal nutrition does not represent a safety concern for the target species, consumers and for the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential skin and eye irritation or potential toxicity by inhalation of the additive under assessment. Riboflavin is a known photosensitiser which may elicit skin and eye photoallergic reactions. The additive under assessment is effective in covering the animals' requirements of vitamin B2 when administered via feed.
