Randomly sampled, aged American mink were tested for anticoagulant rodenticides.
78.8% of mink had detectable residues; bromadiolone being the most commonly found.
The probability of mink exposure to anticoagulants increased by 4.5% per month of age.
Exposure was 1.7 times higher for mink in areas with a high density of farms.
American mink are a potential sentinel species for exposure risks across Europe.
