Risk of Salmonella

Salmonella typhimurium infection is spread easily, either directly or indirectly.1

  1. Horse-to-horse contact – some horses can transmit the bacteria even if they have no signs of illness themselves1
  2. Shared tools, equipment and water buckets1
  3. Foals can become infected while nursing if their mother has released bacteria in her faeces1

Minimising risk

In addition to vaccination, strict hygiene practices and limiting the possibility of exposure to infection are the best ways to protect against salmonella.1

  • Get rid of faeces as soon as possible to avoid exposure to the bacteria.1
  • Isolate any horse or foal that has symptoms.1
  • If you have a sick horse, make sure you don’t spread the infection – always wash your hands after touching the horse, and ensure you don’t walk through watery faeces and then track it around your property.1
  • Don’t be tempted to move any horses that were in contact with the sick horse – they may be incubating the bacteria so you may be spreading the disease to otherwise unaffected horses. Instead, move the sick horse, disinfect its stall and closely monitor the others.1
