Salmonellosis

Surveillance at VLA

The VLA provides veterinary and clinical laboratory expertise. Approximately 10,000 salmonella isolates are examined each year and results are published in the annual publication; 'Salmonella in Livestock Production'.

In addition, field investigations at farms are undertaken for confirmation of infection by sampling, clinical examination of affected stock, collection of epidemiological data and provision of advice on control of infection.

Research at VLA

Research studies include microbiological input to epidemiological investigations of the distribution, persistence and control of salmonella in cattle, pig and commercial egg laying farms.

The VLA has a long history of development and evaluation of salmonella vaccines for poultry and latterly pigs in collaboration with commercial partners.

Reference Laboratory status

The VLA is a holder of the World Organisation for Animal Health (OIE) and UK National Reference Laboratory status for salmonella.
