The reduction of the entry of pathogens in the food chain is an important premise in improving the safety of food of animal origin. Since food animals are the main reservoir for pathogens, the prevalence of pathogens in livestock is of great importance. Unfortunately, classical measures to improve animal health can not exclude the presence of the main food-borne zoonotic agents (Salmonella, Campylobacter, Listeria monocytogenes, verotoxinogene Escherichia coli, Toxoplasma gondii) in "clinically healthy" animals. Absence of pathogens in livestock must be regarded as an unrealistic aim. To achieve an effective improval of product safety through logistical, hygienic or technological measures both farmers and food producers need valid data about the prevalence of pathogens in livestock, in each animal and in raw material of animal origin, respectively. Yet available data are insufficient. New European directives and regulations concerning monitoring and control of zoonosis demand the systematic control of presence of zoonotic agents in livestock and later steps of the food chain.
减少病原体进入食物链是提高动物源性食品安全性的重要前提。由于食用动物是病原体的主要宿主，家畜中病原体的流行情况至关重要。不幸的是，改善动物健康的传统措施无法排除“临床健康”动物中主要食源性人畜共患病原体（沙门氏菌、弯曲杆菌、单核细胞增生李斯特菌、产志贺毒素大肠杆菌、弓形虫）的存在。家畜中不存在病原体必须被视为一个不切实际的目标。为了通过物流、卫生或技术措施有效提高产品安全性，农民和食品生产商分别需要有关家畜、每只动物和动物源性原材料中病原体流行情况的有效数据。然而，现有的数据并不充分。欧洲关于人畜共患病监测和控制的新指令和法规要求系统地控制家畜及食物链后续环节中人畜共患病原体的存在情况。
