   食品伙伴网讯  2024年5月21日,据欧盟食品安全局(EFSA )消息,应欧盟委员会要求,欧盟动物饲料添加剂和产品(FEEDAP)研究小组就博落回提取物(Macleaya cordata (Willd.) R. Br. extract and leaves)作为哺乳和断奶仔猪及其他生长猪饲料添加剂的安全性和有效性发表科学意见。
 
  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 safety and efficacy of Macleaya cordata (Willd.) R. Br. extract and leaves (Sangrovit® Extra) as a zootechnical feed additive for suckling and weaned piglets and other growing Suidae. The additive is standardised to contain a concentration of the sum of the four alkaloids sanguinarine, chelerythrine, protopine and allocryptopine of 1.25%, with 0.5% sanguinarine. Owing to the presence of the DNA intercalators sanguinarine and chelerythrine, a concern for genotoxicity was identified. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) had no safety concerns for the target species when the additive is used at the recommended level of 0.750 mg sanguinarine/kg complete feed for suckling and weaned piglets and other growing Suidae. Since in all consumer categories the exposure to sanguinarine and chelerythrine via the use of Sangrovit® Extra exceeds the threshold of toxicological concern of 0.0025 μg/kg bw per day for DNA reactive mutagens and/or carcinogens, the FEEDAP Panel could not conclude on the safety for the consumers. The additive was shown to be irritant to the eyes but not irritant to skin or a skin sensitiser. The FEEDAP Panel could not exclude the potential of the additive to be a respiratory sensitiser. When handling the additive, exposure of unprotected users to sanguinarine and chelerythrine may occur. Therefore, to reduce the risk, the exposure of users should be reduced. The use of Sangrovit® Extra as a feed additive under the proposed conditions of use was considered safe for the environment. The additive Sangrovit® Extra had the potential to be efficacious in improving performance of weaned piglets at 0.600 mg sanguinarine/kg complete feed. This conclusion was extended to suckling piglets and extrapolated to other growing Suidae.
