  • meat transportBiosecurity means taking steps to prevent the introduction and spread of infectious disease.
  • Foot and Mouth Disease has underlined the importance of biosecurity as a subject that should be continuously addressed as part of normal farm management.
  • Livestock movement onto the farm is one of the biggest risks for disease introduction, so try to adopt a closed herd or flock management policy wherever possible.
  • If you do have to purchase livestock ensure you know as much as possible about their health status. Always aim to purchase animals that have been accredited under a recognised Health Scheme.
  • When moving animals onto the farm, always ensure they undergo an adequate period of quarantine in secure accommodation before introduction to your existing animals.
  • Never mix animals together without considering the possible disease risks.
  • Examine ways in which you can improve farm security to prevent animals or people inadvertently bringing diseases in. Focus on farm boundaries, farm entry and exit points and farm buildings.
  • Poor hygiene and environmental conditions lead to increased risk of infection. Strive to improve standards outside, in animal buildings and in feed storage areas.
  • Develop pro-active strategies for disease prevention rather than adopting a reactive approach. Discuss the development of health plans, disease surveillance programmes and disease response strategies with your veterinary surgeon on a regular basis.
  • The Moredun Foundation has produced newsheets on a number of sheep and cattle diseases that improved biosecurity can help to control. Please contact your veterinary surgeon or refer to these newsheets for further information.
