欧盟评估一种维生素B2/核黄素作为所有动物饲料添加剂的安全性和有效性

 

　　据了解，该添加剂是由Eremothecium ashbyi CCTCCM 2019833生产的。由于缺乏关于添加剂毒理学特征的数据，包括其潜在的遗传毒性，专家小组无法就添加剂对目标物种、消费者和使用者的安全性作出结论。专家小组的结论是，使用该产品作为饲料添加剂不会对环境造成影响。经过评估的添加剂可以有效地满足动物通过饲料给药对维生素B₂的需求。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 feed additive Vitamin B2/Riboflavin produced by Eremothecium ashbyi CCTCCM 2019833 for all animal species and categories. The additive contains a minimum content of riboflavin of 5%. The production strain has been characterised and data showed that viable cells are not present in the final additive. The additive is not a skin or eye irritant nor a skin sensitiser, but it is considered to be a respiratory sensitiser. The lack of data on the toxicological profile of the additive, including its genotoxic potential, did not allow the Panel to conclude on the safety of the additive for the target species, consumers and users. The FEEDAP Panel concluded that the use of the product as a feed additive poses no concerns for the environment. The additive under assessment is effective in covering the animals’ requirements for vitamin B2 when administered via feed.
