The epidemiological relationship between Salmonella isolated from poultry meat and sewage effluents at a long-stay hospital.

Between February 1988 and March 1989 chicken carcases delivered to the kitchen of a long stay psycho-geriatric hospital were screened every week for salmonella contamination. While 214 of 477 (45%) individual carcases carried one or more salmonella types, every single consignment examined contained affected carcases. Simultaneously, sewers draining the residential accommodation and excluding kitchen effluent, were also monitored. Thirty out of 79 (38%) of Moore's swabs were positive for salmonella. There was a statistically significant association between the salmonella types isolated from chicken and those isolated from sewers the following week. Following a change in kitchen policy to order only cooked chicken there was a significant reduction in the isolation of salmonella from the sewers.

Poultry-borne salmonellosis in Scotland.

Between 1980-5, 224 outbreaks of salmonellosis associated with poultry-meat were reported in Scotland. In total 2245 persons were affected, 12 of whom died. Twenty-one salmonella serotypes were identified from those affected, while 33 serotypes were isolated from poultry during routine monitoring and disease investigation. Existing measures to prevent the spread of salmonellae within poultry flocks and processing plants are failing. It is suggested that irradiation of poultry-meat may be the only effective method of reducing the public health problem of poultry-borne salmonellosis.

An epidemiological study of Salmonella montevideo by biotyping.

Among 622 cultures of Salmonella montevideo, 27 biotypes belonging to two biogroups were recognized. One biogroup (10di) was predominant in all animals in Scotland but only in sheep in England and Wales. The other (biogroup 2d) was responsible for almost all human, cattle and poultry infection in England and Wales, but only 24% of human infection in Scotland.

Milkborne salmonellosis in Scotland 1980 to 1982.

In Scotland between 1980 and 1982 there were 21 episodes of milkborne salmonella affecting a total of 1090 persons (range one to 654). There were eight deaths, including two children, in people associated with these outbreaks. The problem of milkborne salmonellosis continues to be greater in Scotland, where dairy herds on average are larger and a greater proportion of raw milk is consumed, than elsewhere in Britain. It is anticipated that legislation requiring the pasteurisation of virtually all milk sold for human consumption in Scotland by August 1983, will help to correct the situation.

Salmonella montevideo infection in sheep and cattle in Scotland, 1970-81.

Outbreaks of abortion associated with infection by Salmonella montevideo have affected sheep in the east, especially the south-east, of Scotland each year since 1972. Disease in the north and north-east was usually less severe. Between 1 January 1970 and 31 December 1981, a total of 67 incidents affecting sheep were reported by veterinary laboratories to the Communicable Diseases (Scotland) Unit, 87% of which presented during the main lambing months of February, March and April. Twenty-one episodes of bovine infection were also recorded over the same period, 17 of which involved single animals only, usually an aborted cow or a scouring calf. Despite intensive investigations, neither the origin nor the mode of spread of S. montevideo infection among sheep and cattle in Scotland have been established with any certainty, although there has been considerable evidence indicating the role of scavenging wild birds, particularly seagulls, as vectors transmitting infection to other farms in the same district. Also largely unexplained are the differences in the epidemiology and clinical pattern of disease in the south-east compared to the north and north-east, while sheep in the west of Scotland have remained virtually unaffected throughout.

Interprofessional liaison in Scotland.

Communication between the medical, veterinary and environmental health professions has been established in Scotland since the early 1970s and was strengthened by the introduction of the Zoonoses Order 1975. The secondment of a veterinary officer to the Communicable Diseases (Scotland) Unit in Glasgow provides veterinary expertise on matters relating to public health, in addition to improving liaison, surveillance and the other functions of the unit.

Human and animal salmonellosis in Scotland associated with environmental contamination, 1973-79.

Twenty-six incidents of salmonellosis occurring in Scotland between 1973 and 1979 and attributed to environmental pollution are reviewed. The apparent sources of pollution were sewage effluent (10 incidents), septic tank effluent (eight), sewage sludge (three), seagulls (three) and abattoir effluents (two). Cattle were the species predominantly affected. Human infection was primary in three incidents and was secondary to bovine infection in another four. Thirteen salmonella serotypes were recovered from infected humans or animals and 17 during related environmental investigations. The factors causing pollutions and possible control measures are discussed.

An unusual sequel to imported Salmonella zanzibar.

In August, 1980 a rare serotype S. zanzibar was isolated in the North of Scotland from a man home on leave from Malaysia, whence he returned in November having been bacteriologically negative 2 months previously. In December however, S. zanzibar was isolated from a bulk milk sample taken at a nearby dairy farm. No illness occurred among milking cows which had been brought inside from pasture in mid-October. Since 1972 a variety of different salmonella serotypes had been identified in cattle, milk and other samples at this farm, with seagulls being implicated as the vector transmitting infection from the sewage of a local town on to farmland and an adjacent loch. Although water from this source has not been used in recent years for drinking by cattle, it is utilized for washing floors within the dairy premises. Since 1979, following an outbreak affecting consumers, all milk produced at the farm has been pasteurized.
