New UK research reveals that pheasants may significantly increase the risk of Lyme disease in woodland areas. Scientists found that ticks are more likely to carry Borrelia, the bacteria that causes Lyme disease, in areas where pheasants are released for game shooting.
Findings from Woodland Surveys
The study, conducted by the University of Exeter and the UK Health Security Agency (UKHSA), surveyed 50 woodland sites in southwest England. Half of these sites had regular pheasant releases, while the other half did not. According to BBC News, ticks in pheasant-release areas were 2.5 times more likely to carry the bacteria.
Researchers found Borrelia in 7.8% of ticks collected from pheasant-release woodlands, compared to just 3.2% in control areas. Emile Michels, a lead researcher, explained that pheasants are “known to have a relatively high likelihood of contracting and retransmitting the bacteria.”
Expert Insights on Health Implications
While the presence of bacteria has increased, health experts urge caution. Dr. Jolyon Medlock of UKHSA stated: “We do not have data on the resulting impact on human health, including evidence of Lyme infection.” He added that more research is needed to better understand how gamebird practices affect disease spread.
Data from Southern England and Public Risk
Separate findings published by News-Medical.net support these results. In a broader study of 72 woodlands, ticks in pheasant-release sites were also 2.5 times more likely to be infected. Lead researcher Dr. Will Pearse emphasized that pheasants act as “competent hosts,” meaning they pass the bacteria to feeding ticks.
“Our findings suggest pheasants may play a significant role in increasing the risk of Lyme disease by boosting the number of infected ticks.”— Dr. Will Pearse, University of Exeter
What This Means for Public Health
The UK releases up to 50 million pheasants each year, mostly for sport shooting. This widespread release may raise the density of infected ticks in recreational areas, increasing risks for hikers, gamekeepers, and pet owners. Though Lyme disease symptoms vary, early signs often include fever, rash, and fatigue. Early treatment with antibiotics is effective in most cases.
Staying Safe Outdoors
The UKHSA advises the public to take basic precautions in tick-prone areas. These include wearing long sleeves, using insect repellent, and checking for ticks after outdoor activities.
Conclusion
These findings highlight the growing need to consider wildlife management in efforts to reduce Lyme disease risks. As pheasants are confirmed carriers of the Lyme-causing bacteria, further studies and smarter gamebird release practices may help protect public health.
