Study Finds Rat Poison Harmful to Fish in German Rivers
Research conducted by scientists from the Federal Institute of Hydrology and the Bavarian Environment Agency has revealed that rat poison can cause severe symptoms in fish, potentially leading to their death. The long-term trials, funded by the German Environment Agency (UBA), were carried out in labs using rainbow trout.
In a concerning revelation, the UBA explained that rat poison induces delayed blood clotting inhibition, anemia, internal and external bleeding, and ultimately death in fish. The active ingredient, Brodifacoum, found in many rat poisons and detected in wild fish at comparable concentrations, accumulates in the fish's liver.
The UBA cautioned that many fish in German rivers are contaminated with rat poison. In addition, the scientists discovered substances used in baits in liver samples from otters and two fish-eating bird species, indicating a wider impact on aquatic life.
These baits, laced with rat poison, are sometimes placed near waterways when fighting rats. When they come into contact with water, the baits dissolve, releasing the toxic ingredients into the water cycle. Previous studies have identified these active ingredients in various other wildlife species.
To mitigate the issue, the UBA recommends the use of waterproof bait stations, which will be mandatory in sewers and near waterways across the European Union by 2026. Long-term, denying rats access to food sources and nesting places is a more effective strategy, the UBA suggests.
In an effort to reduce the number of rats and, subsequently, the use of rat poisons, citizens can safely dispose of food waste. By doing so, we can potentially minimize the hazardous impact on our aquatic ecosystems.

While the specific long-term effects of Brodifacoum on fish populations in German rivers are not explicitly detailed in the research, our analysis of relevant environmental and scientific insights suggests potential concerns. Brodifacoum, a second-generation anticoagulant rodenticide, poses a risk due to its high toxicity, bioaccumulation, and environmental persistence. As it could lead to subclinical and clinical health effects in fish populations, further studies on German rivers might be necessary to accurately quantify its impact.
- The community policy could address the issue of rat poison contamination in rivers, mandating the use of waterproof bait stations to minimize the release of toxic ingredients into waterways.
- In light of the health-and-wellness concerns for fish species, an employment policy focusing on environmental-science research could be implemented to study the long-term effects of Brodifacoum on fish populations and aquatic ecosystems.
- To combat the problem of rat populations and the subsequent use of harmful rat poisons, an employment policy in fitness-and-exercise and health-and-wellness sectors could promote education on preventative measures, such as safely disposing of food waste to deter rats and protect local ecosystems.
