SPF programs have been established in various countries, particularly in Denmark and Switzerland these programs are already well advanced. The system proves to be advantageous for export dealings but also with regard to public health. Dalland is an internationally operating Dutch pig breeding organisation. In 1989 a SPF nucleus breeding farm was established in North-East France. A special program was set up for the supply of animals from this SPF nucleus. In this paper it is concluded that SPF can be economically beneficial. Under certain well-described circumstances SPF breeding seems feasible. Its is suggested that in future pigs could be produced that will be free of enteropathogens of interest to public health, e.g. Salmonella, Campylobacter and Yersinia enterocolitica.
无特定病原体（SPF）计划已在各国建立，特别是在丹麦和瑞士，这些计划已经相当成熟。该系统已证明不仅在出口业务方面，而且在公共卫生方面都具有优势。达兰德是一家从事国际业务的荷兰种猪繁育组织。1989年，在法国东北部建立了一个无特定病原体核心繁育场。为此核心繁育场的动物供应制定了一个特殊计划。本文得出结论，无特定病原体养殖在经济上是有益的。在某些详细描述的情况下，无特定病原体繁育似乎是可行的。建议未来可以培育出对公共卫生有影响的肠道病原体（如沙门氏菌、弯曲杆菌和小肠结肠炎耶尔森菌）检测呈阴性的猪。
