title: A note on salmonella excretion in the black headed gull (Larus ribibundus) feeding at sewage treatment works.
abstract: The range of salmonella serotypes found in sewage sludge and in the faeces of black headed gulls (Larus ribibundus) feeding on the sludge was investigated. A close association was demonstrated between the serotypes found in both types of sample. Salmonella takoradi (a serotype which is uncommon in Scotland) appeared in the sludge for two short periods during the twelve week study and on both occasions it was later found in the gull faeces. It was shown that gulls become infected after feeding on contaminated sewage sludge but that the infection is probably short-lived.
