    FORWARD

    This updated version of the NHS Greater Glasgow and Clyde Outbreak Control Plan for Food and Waterborne Gastro-intestinal illness (including GI infection) brings together the two outbreak control plans that operated in the former NHS Greater Glasgow and NHS Argyll and Clyde. It was developed in conjunction with the Public Health-Environmental Health-Med-Vet Working Group. It has been compiled by the Public Health Protection Unit and contributed to, and endorsed by, all six local authority departments of environmental health and by Scottish Water. It also has the approval of the Scottish Parasite Diagnostic Laboratory and our attending medical and food microbiologists. This plan should be read in conjunction with the national guidance on the subject (Guidance on the Investigation and Control of Outbreaks of Foodborne Disease in Scotland published jointly by the FSA(S) and the Scottish Government) and the NHS Greater Glasgow and Clyde Generic Incident Management/Outbreak Control Plan. The Appendix B includes a useful list of officers and agencies that one might need to get in touch with during an outbreak and their contact details. We would welcome feedback on the usefulness of this document at any point in the future in order to help us improve on it for future updated versions.

    DEFINITIONS CBRN - Used to refer to deliberate releases of chemical, biological, radiological and nuclear agents by what is inferred to be subversive and/or criminal forces. Cryptosporidiosis - the diarrhoeal infection caused by the Cryptosporidium parasite. Cryptosporidium - the plasmodium protozoan parasite, some species of which can cause Cryptosporidiosis. EHO - Environmental Health Officer, an officer trained in environmental health usually employed by local authority environmental health services (LA/EHS). The EHO shares statutory responsibility with the NHS Board for protecting and improving the public health within their geographical boundaries. HACCP - Hazard Analysis Critical Control Point, a food safety management system used by food businesses to identify vulnerable points (critical control points) and to document appropriate control measures. Incident Management Team (IMT) An IMT is a team of professionals drawn from multiple agencies with the common goal of investigating and bringing under control a potential threat to the public health. It is convened comprising the relevant representatives from the stakeholder agencies with an interest in a public health incident. A public health incident involves a potential threat to the public health (a scare involving food or water in this context, but that has yet to, and may never, cause illness). NHS24 - The response service provided by highly qualified nursing staff that is accessed by the public out of hours and that is used to perform a telephone-based triage including referral to medical services including A&E, domiciliary visit, etc. All areas across Greater Glasgow and Clyde are now included in NHS 24 and the appropriate GP out of hours service for each area is accessed through this mechanism. NHSGGC - The entire NHS within Greater Glasgow and Clyde including all Divisions and the Board. Covers all or part of the six councils named on the coversheet of this plan. NHS GEMS - Glasgow Emergency Medical Service, the GP-based and district nurse-based primary care service available out of hours in the Greater Glasgow and Clyde area, that is accessible via NHS24 after hours. Norovirus - Norwalk-like virus (a common cause of viral gastroenteritis) traditionally thought to cause illness in the winter months hence the term 'winter vomiting disease' - but now found to be occurring at any time of the year. Outbreak - Two or more associated or linked cases of illness or infection; a greater than expected rate of illness or infection in a population; or a single case of certain serious, possibly contagious infections suggesting that there will be many more in the community (see major and minor outbreak definitions overleaf). Outbreak Control Team (OCT) An OCT is convened when any representative from one of the three participating core agencies (NHS Board, Local Authority Environmental

    Health Department, or hospital microbiologist) feels there has been an outbreak of illness (related to food or water in this context). Problem Assessment Group (PAG) - A PAG is an informal group that can communicate either via the telephone, e-mail, fax or in person consisting of any representative from at least two of the three participating core agencies. Normally, a PAG would involve informal, initial communication about a possible incident or outbreak before it has been established that a formal IMT or OCT should be convened. The key members of a PAG would normally be the Consultant in Public Health Medicine (CPHM), an Environmental Health Officer (EHO) and a water authority scientific officer, if the event is suspected to be waterborne, or alternatively, the CPHM, EH
