Secondary poisoning hazards in stone martens (Martes foina) fed bromadiolone-poisoned mice

Abstract:
Stone martens (Martes foina) are particularly exposed to secondary poisoning by feeding on anti-coagulant-loaded rats and mice in premises. This study indicates that the risk can be considered relatively small as up to 31 bromadiolone-loaded mice were consumed during four days by a single stone marten without symptoms of poisoning.
Insights
Stone martens may face secondary poisoning risks from consuming rodenticide-laced prey. However, this study found a single stone marten (Martes foina) tolerated 31 bromadiolone-loaded mice over four days without ill effects, suggesting a low risk.
Area of Science:
- Wildlife toxicology
- Mammalian ecology
- Pest control impacts
Background:
- Stone martens (Martes foina) are susceptible to secondary poisoning via anticoagulant rodenticides.
- Ingestion of poisoned rodents is a primary exposure route for predators in urban and rural environments.
Purpose of the Study:
- To assess the risk of secondary poisoning in stone martens from consuming anticoagulant-treated prey.
- To determine the tolerance level of stone martens to bromadiolone exposure.
Main Methods:
- Observation of a single stone marten's consumption of bromadiolone-loaded mice over a four-day period.
- Monitoring for any clinical signs of poisoning in the observed animal.
Main Results:
- A single stone marten consumed up to 31 bromadiolone-loaded mice.
- No symptoms of poisoning were observed in the stone marten during the study period.
Conclusions:
- The risk of secondary poisoning for stone martens from bromadiolone appears relatively low, even with significant ingestion.
- Further research is warranted to establish definitive safe exposure levels for Martes foina.
