Livestock Biosecurity and Welfare: Disease Prevention

Biosecurity measures prevent disease entry into livestock farms, reducing the welfare burden of infectious disease at population scale.

Key Facts

Biosecurity encompasses practices that prevent introduction and spread of pathogens on farm
Foot dips, restricted visitor access, quarantine of new stock, and protective clothing are key measures
Disease outbreaks cause significant welfare harm — mass culls for disease control affect millions of animals
Avian influenza, African Swine Fever, and Foot and Mouth Disease have major welfare implications at outbreak scale
Farm biosecurity pays dividends in reduced disease treatment, mortality, and lost production
Bio-secure farms maintain animal health at lower antibiotic use, supporting stewardship goals

Welfare Considerations

Biosecurity is a welfare investment that protects animals from the suffering of serious infectious diseases. Mass culls of millions of birds during avian influenza outbreaks represent one of the largest-scale acute welfare events in commercial animal farming — events that good biosecurity significantly reduces the risk of triggering. At the farm level, disease prevention through biosecurity maintains animal health, reduces treatment frequency, and supports the good conditions that underpin positive welfare. The welfare case for biosecurity is complementary to the economic case — healthy animals live better lives and produce more efficiently. Welfare-centred biosecurity is an investment in prevention rather than a reactive response to disease.

What You Can Do

Support farms that demonstrate strong biosecurity practices through certification
Advocate for government support for biosecurity infrastructure in livestock farming
Encourage producers to develop and practice disease outbreak response protocols
Support international cooperation on transboundary disease control to reduce mass culling events
Engage food companies about biosecurity standards in their supply chains
