Biosecurity: In brief

Biosecurity is the set of management practices that protect your flock from the introduction and spread of diseases.

Footrot and CODD are both infectious causes of lameness. This means that they can spread between sheep, either via direct contact or via the environment. Reducing this spread involves minimising contact between lame and healthy sheep, and avoiding environments where the bacteria are likely to survive well e.g. damp bedding.

Buying in new sheep is a risk for introducing infectious diseases like footrot and CODD to your flock. Follow the checklist below to minimise the risk of introducing disease:

  • Learn the history of the flock you are buying from
  • Don't buy lame animals
  • Check the feet of sheep you are buying
  • Quarantine new sheep for 4 weeks
  • Monitor for lameness during quarantine and treat as needed
  • Footbath before joining the main flock

Watch the video to find out why quarantine is important.


There are several things you can do to minimise the spread of infectious lameness between sheep within your flock:

  • Separate lame sheep from healthy sheep
  • Move feeders and water troughs regularly to avoid ground becoming poached
  • Spread lime in areas where sheep are likely to gather e.g. gateways, around feeders
  • Reduce stocking density
  • Clean and disinfect pens regularly and make sure bedding is clean and dry during housing
