Salmonella is a bacterial infection of animals (including livestock) and birds.
Salmonella can be transmitted to humans:
- in contaminated food
- through exposure to infected animal products and body parts
- through exposure to infected animal housing and feed
Suspicion and confirmation
Contact your private vet if you suspect salmonella in your herd or flock.
Signs can vary between species but include:
- diarrhoea (that may contain blood or mucus)
- vomiting and fever
Many animals with salmonella have no signs of illness and appear healthy.
Transmission, prevention and treatment
Salmonella occurs naturally in the intestines of many different animals. Animals can become infected:
- through their environment
- by eating contaminated food
- from their mothers before they are born or hatched
Animals with salmonella shed the bacteria in their stool. This can contaminate:
- other body parts - fur, feathers or scales
- the areas where these animals live and roam, including their feed-stuffs
To help prevent and control salmonella:
- you should follow good biosecurity measures
- governmental national control programmes are in place to reduce levels of infection in food animals, especially poultry
Treatment can be difficult and ineffective. Especially in poultry flocks where a large number of animals may be infected. Infected poultry will need to be isolated and slaughtered. With certain other species, you can use antibiotic treatment. You should discuss this with your vet.
