Human infection in Tayside, Scotland due to Salmonella serotype Livingstone.

Livingstone was the third most common salmonella serotype isolated from cases of human salmonellosis in the Tayside region of Scotland in 1989-1991; latterly, it spread to Grampian region. The significant upsurge of Livingstone in these two Scottish regions was not matched by similar increases in its frequency of isolation from human cases of salmonellosis in other regions of Scotland or elsewhere in the UK. Although Salmonella Livingstone is usually associated in the UK with incidents of infection among poultry flocks, our detailed investigations found no clear evidence that poultry, eggs or poultry-related products were responsible for this outbreak.
