Moniliformin (MON) is a mycotoxin with low molecular weight primarily produced by fungi and occurring predominantly in cereal grains. Following a request of the European Commission, the CONTAM Panel assessed the risk of MON to human and animal health related to its presence in food and feed. The limited information available on toxicity and on toxicokinetics in experimental and farm animals indicated haematotoxicity and cardiotoxicity as major adverse health effects of MON. MON causes chromosome aberrations but no genotoxicity data and no carcinogenicity data were identified. Due to the limitations in the available toxicity data, human acute or chronic health-based guidance values (HBGV) could not be established. The margin of exposure (MOE) between the no-observed-adverse-effect level (NOAEL) of 6.0 mg/kg body weight (bw) for cardiotoxicity from a subacute study in rats and the acute upper bound (UB) dietary exposure estimates ranged between 4,000 and 73,000. The MOE between the lowest benchmark dose lower confidence limit (for a 5% response - BMDL) of 0.20 mg MON/kg bw per day for haematological hazards from a 28-day study in pigs and the chronic dietary human exposure estimates ranged between 370 and 5,000,000 for chronic dietary exposures. These MOEs indicate a low risk for human health but were associated with high uncertainty. The toxicity data available for poultry, pigs, and mink indicated a low or even negligible risk for these animals from exposure to MON in feed at the estimated exposure levels under current feeding practices. Assuming similar or lower sensitivity as for pigs, the CONTAM Panel considered a low or even negligible risk for the other animal species for which no toxicity data suitable for hazard characterisation were identified. Additional toxicity studies are needed and depending on their outcome, the collection of more occurrence data on MON in food and feed is recommended to enable a comprehensive human risk assessment.
串珠镰刀菌素(MON)是一种低分子量霉菌毒素,主要由真菌产生,主要存在于谷物中。应欧盟委员会的要求,CONTAM专家组评估了食品和饲料中MON对人类和动物健康的风险。实验动物和农场动物中关于毒性和毒代动力学的现有信息有限,表明血液毒性和心脏毒性是MON的主要不良健康影响。MON会导致染色体畸变,但未发现遗传毒性数据和致癌性数据。由于现有毒性数据存在局限性,无法确定基于人类急性或慢性健康的指导值(HBGV)。大鼠亚急性研究中,心脏毒性的未观察到有害作用水平(NOAEL)为6.0毫克/千克体重(bw),与急性膳食暴露上限(UB)估计值之间的暴露边际(MOE)在4000至73000之间。猪28天研究中,血液学危害的最低基准剂量下限置信限(5%反应 - BMDL)为0.20毫克MON/千克体重/天,与慢性膳食人类暴露估计值之间的MOE在慢性膳食暴露时为370至5000000之间。这些MOE表明对人类健康风险较低,但存在高度不确定性。家禽、猪和水貂的现有毒性数据表明,在当前饲养方式下估计的暴露水平下,这些动物因饲料中MON暴露而面临的风险较低甚至可忽略不计。假设与猪的敏感性相似或更低,CONTAM专家组认为,对于未鉴定出适合危害特征描述的毒性数据的其他动物物种,风险较低甚至可忽略不计。需要进行更多的毒性研究,并根据研究结果,建议收集更多关于食品和饲料中MON的出现数据,以便进行全面的人类风险评估。
