Abstract Anticoagulant rodenticides (ARs) are an effective tool used to suppress rodent populations in urban and agricultural settings reduce human disease risk economic loss, but widespread use has resulted adverse effects on predators globally. Attention largely been focused impacts of ARs raptors, although there is increasing evidence that mammalian carnivores also impacted. We conducted a literature review assess the extent which have documented wild globally identify potential overlap with imperiled carnivores. found small growing body documenting exposure 8 Carnivora families, Mustelidae (64% studies), Canidae (44%) Felidae (23%) most represented. At least 11 different AR compounds were carnivores, authors claimed caused mortality at one individual 33.9% species studied. listed as threat for 2% Red List we 19% had ranges countries Collectively, our highlights need prioritize conservation attention role global carnivore declines. suggest (1) expanding monitoring research outside northern hemisphere, (2) supporting long‐term understand spatial temporal variation risk, (3) across trophic levels urban–wildland gradient 4) further understanding point morbidity occur.

Poisoning caused by coumarin-type anticoagulant rodenticides (ARs) stands as the predominant method for controlling rodents globally. ARs, through secondary poisoning, pose a significant threat to predators due their lethal and sublethal effects. We examined concentration of accumulated ARs in liver samples mostly road-killed steppe polecats (Mustela eversmanii) European (M. putorius) collected throughout Hungary between 2005 2021. The polecat were found mainly from Eastern Hungary, while Western Hungary. measured six residues HPLC-FLD.

Anticoagulant rodenticides (ARs) are one of the most toxic groups compounds currently used worldwide for rodent pest control. Toxic baits often, directly or indirectly, ingested by non-target animals, resulting in secondary poisoning and frequently affecting apex predators. Their presence many species raptors is quite common, particularly scavenger species, with some these acting as sentinels substances environment.
