Deer Appears Intoxicated, Prompting Police Alert
On May 5, the Gendarmerie de Saône-et-Loire posted a Facebook video of a deer running in circles, rolling and repeatedly falling in a meadow beside a road. The animal’s erratic behavior prompted a warning that it may have ingested fermented fruit and become intoxicated.
Seasonal Fermentation of Fruit and Its Effects on Wildlife
Officials explain that in spring, buds, over-ripe fruit and decaying vegetation naturally ferment, producing ethanol—the same alcohol found in beer, wine and spirits. Some studies indicate mammals metabolize ethanol similarly to humans, possibly experiencing intoxication, while other researchers dispute that effect, noting species-specific differences.
Gendarmerie de Saône-et-Loire Leads the Warning
The regional gendarmerie, the law-enforcement branch of the French National Gendarmerie for Saône-et-Loire in Burgundy, issued the alert. Its statement emphasized that “not all road users are sober” and urged motorists to adjust their driving accordingly.
Observed Deer Behavior in the Video
The footage shows the deer repeatedly chasing its tail, stumbling, and shaking its head as if disoriented. At times it collapses, lies motionless, then regains balance and continues across the field, repeating the pattern several times.
Potential Road Safety Risks
Police identified four hazards: sudden crossing, inconsistent trajectory, temporary immobilization, and disorderly escape. They warned that such unpredictability can cause rapid collisions, especially on secondary roads or at night.
Official Statements & Responses
The alert advised drivers to “slow down, anticipate, avoid sudden turns, and be extra vigilant in wooded areas,” and to keep a safe distance from wildlife, avoiding abrupt steering when a deer appears.
Scientific Perspective and Dissent
While the gendarmerie links the behavior to ethanol ingestion, some scientists note that mammals process ethanol differently and the level of intoxication in deer is uncertain, highlighting a need for further research on wildlife responses to fermented foods.
Conflicting Reports & Gaps
Police have not confirmed any accidents linked to the deer, nor provided data on incident frequency. The cause of the behavior remains unverified beyond the fermented fruit hypothesis.
What’s Next
The gendarmerie said the alert will remain active through the spring fruit-ripening period and that it will issue further updates if additional incidents are reported.
