All livestock keepers need to be aware of the need for strict biosecurity and hygiene on their premises:


  • Protects your neighbours and the countryside
  • Keeps new diseases out
  • Reduces the spread of disease
  • Keeps more animals healthy
  • Cuts cost of disease prevention and treatment
  • Improves farm efficiency

How Disease Spreads:

  • Movement of animals, people and machinery between and within farms
  • Farm visitors - people and vehicles
  • Introduction of new animals
  • Contact with neighbours' livestock
  • Shared farm equipment
  • Contamination by vermin and wildbirds
  • Animals drinking from contaminated rivers and streams

How to Stop It - KEEP IT CLEAN!

  • Be aware of the need for biosecurity
  • Make a herd/flock plan with your vet including isolation for new or returning stock
  • Don't bring infection onto your farm, or spread it around the farm, on your clothes, footware or hands
  • Where possible, limit and control farm visitors - people and vehicles
  • Keep farm access routes, parking areas, yards, feeding and storage areas clean and tidy
  • Have pressure washers, brushes, hoses, water and disinfectant available and make sure visitors use them
  • Don't allow contact with neighbours' livestock - maintain your fences
  • Don't share injecting and dosing equipment - it it can't be avoided cleanse and disinfect thoroughly
  • Clean then disinfect any farm machinery/equipment if sharing with a neighbours' farm
  • Implement a pest control programme
  • Fence off streams and rivers - supply clean fresh drinking water in troughs
  • Keep livestock away from freshly spread slurry for six weeks
  • Ensure identification and record keeping are accurate and up to date
  • Dispose of fallen stock properly

Buying New Stock - Returning your stock to the farm

Always know the health status of animals
you are buying or moving!

  • Incoming and returning stock should be kept separate from the rest of the herd/flock - discuss with your vet and agree a testing programme
  • Use separate equipment and staff or handle isolated stock last
  • Keep isolation buildings as near as possible to the farm entrance and separate from other livestock buildings by 3 metres
  • If using a paddock, keep it separated by at least 3 metres (with double fencing) from other animals on the farm
  • Dispose of bedding so other livestock can't have access to it.
