Livestock disease importation

Area of Science:

• Veterinary epidemiology
• Animal health policy
• Disease surveillance

Background:

• Liberalized British livestock importation policies post-1969 increased the influx of pedigree animals.
• This policy shift coincided with an increase in disease introductions into the United Kingdom.
• Disease transmission vectors include live animals, waste food, and wild birds.

Purpose of the Study:

• To analyze the impact of liberalized livestock importation on disease introduction in Britain.
• To review the status of diseases introduced since 1968.
• To advocate for a review of current animal health policies.

Main Methods:

• Review of historical disease introduction data linked to livestock imports.
• Analysis of disease eradication and control efforts.
• Assessment of policy implications on animal biosecurity.

Main Results:

• Fourteen distinct diseases, including two novel conditions, were introduced into Britain since 1968.
• Six of the introduced diseases have been successfully eradicated.
• The remaining diseases necessitate continued governmental or voluntary control strategies.

Conclusions:

• Liberalized livestock importation policies present a significant biosecurity risk.
• Effective disease control requires a balance between trade facilitation and public health.
• A comprehensive review of current importation policies and disease management strategies is urgently needed.
