A recent preprint study from the University of Bristol sheds light on the biosecurity practices of individuals in the UK who regularly come into contact with birds. While measures to protect bird health are widely adopted, the study indicates that human health risks, particularly regarding avian influenza transmission to people, are not as prominently addressed.
High Adoption of Bird-Focused Biosecurity
The study found that 89% of participants (approximately half of which are poultry farmers) washed their hands after handling birds, and 78% used disinfectant footwear dips. These practices are primarily aimed at preventing the spread of avian influenza among bird populations.
Limited Human Health Considerations
Despite robust measures for bird health, the perceived risk of avian influenza to human health was not associated with the use of personal protective equipment (PPE) for humans. This suggests a gap in addressing the zoonotic potential of avian influenza among those in close contact with birds.
Influence of Farm Size on Practices
Individuals working with larger flocks were more likely to implement PPE measures, indicating that farming scale may influence the adoption of biosecurity practices.
The study highlights the need for a more balanced approach to biosecurity that equally considers the health risks to humans. Enhancing awareness and training among individuals in close contact with birds could help mitigate the potential for zoonotic transmission of avian influenza.
While the UK has made significant strides in protecting bird populations from avian influenza, this study underscores the importance of extending biosecurity measures to safeguard human health as well. Further research and policy development are essential to address these gaps and ensure comprehensive protection against zoonotic diseases.
