Summary
# Editorial Summary Understanding where horses are actually located remains fundamental to designing effective disease surveillance and control strategies, yet the UK lacks systematic population-level data on equine premises. Robin and colleagues examined the National Equine Database to assess whether owner address records—the most readily available data point—could serve as a practical proxy for horse location during disease outbreaks. Their analysis of 1440 horses from an Animal Health Trust syndromic surveillance database revealed that approximately 90% were kept within 10 km of their registered owners' addresses, suggesting owner location provides reasonable geographical resolution for disease control purposes at a broad scale. However, the researchers found that most UK passport-issuing organisations failed to routinely collect explicit information about where horses were actually kept, limiting the utility of current licensing systems for epidemiological mapping. For practitioners involved in disease response, this work highlights a significant gap: whilst owner addresses offer a useful starting point for outbreak investigations, they cannot replace direct premises records, and better standardised collection of livery and grazing location data across the industry remains essential for modern disease control planning.

Practical Takeaways
- •Owner address data can be a reasonable starting point for disease tracing and outbreak response, though direct knowledge of actual horse locations remains preferable
- •Veterinarians and equine organisations should advocate for consistent recording of yard/facility locations in addition to owner addresses to improve disease surveillance accuracy
- •Current gaps in population data collection mean practitioners may need to supplement official databases with local knowledge during disease investigations
Key Findings
- •Few UK passport-issuing organisations collect data on where horses are kept beyond owner address details
- •90% of 1440 horses examined were kept within 10 km of their owners' addresses
- •Owner location may serve as a proxy for horse location at a geographical resolution suitable for disease control planning
- •The National Equine Database requires further evaluation for epidemiological utility in disease control measures
