Several systems are being used in England to record information about the health of pigs. The British Pig Health Scheme (BPHS), the National Animal Disease Information System (NADIS), the Zoonoses Action Plan (ZAP) for Salmonella and the Veterinary Investigation Diagnosis Analysis (VIDA) system have been assessed to make recommendations for their future separate or joint development. The structure, organisation, processes, data quality, dissemination, utilisation and acceptance of each system have been assessed. Information was extracted from documents and websites, and informal interviews were conducted with technical experts and stakeholders. The systems covered a broad range of objectives, used variable approaches and operated at very different scales and budgets. There was a high level of awareness and involvement by the industry. Common weaknesses of the systems were the lack of in-depth quantitative analysis of the data, the lack of assessment of each system's impact, and the unknown level of bias as a result of the voluntary or selective participation in them.
