Medicinal products provide a benefit to the intended patient or target animal; however as a cross contaminant, they provide no benefit to the patient or target animal and may even pose a risk. Hence, the presence of such contaminants should be managed according to the risk posed which in turn are related to levels that can be considered safe for all populations. To this end, health based limits through the derivation of a safe threshold value should be employed to identify the risks posed. The derivation of such a threshold value (e.g. permitted daily exposure (PDE) or threshold of toxicological concern (TTC) should be the result of a structured scientific evaluation of all available pharmacological and toxicological data including both non-clinical and clinical data. Deviation from the main approach highlighted in this guideline to derive such safe threshold levels could be accepted if adequately justified. 当在共用设施生产不同的药用产品时，潜在交叉污染是受到关注的。药用产品提供为患者或者目标动物提供预期医 疗溢处，然而，交叉污染，没有向病人或者目标动物提供任何溢处，甚至可能带来风险。因此，应限制药用产品污 染物在一个对所有人群认为是安全的水平。为此，基于健康限度，通过推导安全阀值应该被用于识别风险。偏离阀 值（如，每日允许暴露（PDE）或毒理学相关阀值（TTC）应来自结构化的对包括非临床和临床数据的所有药理 学与毒理学数据科学评价。如果有充分合理的理由，来自这条指导原则中强调的主要方法获得的安全阀值水平偏离 可以接受。 1. Introduction (background) 第一章：第一章：介绍（背景）介绍（背景） During the manufacture of medicinal products accidental cross-contamination can result from the uncontrolled release of dust, gases, vapours, aerosols, genetic material or organisms from active substances, other starting materials, and other products being processed concurrently, as well as from residues on equipment, and from operators clothing. Due to the perceived risk, certain classes of medicinal product have previously been required to be manufactured in dedicated or segrega
