Despite widespread use and benefit, there are
growing concerns regarding hazards of second-generation
anticoagulant rodenticides to non-target wildlife which
may result in expanded use of first-generation compounds,
including chlorophacinone (CPN). The toxicity of CPN
over a 7-day exposure period was investigated in American
kestrels (Falco sparverius) fed either rat tissue mechanically-
amended with CPN, tissue from rats fed Rozol bait
(biologically-incorporated CPN), or control diets (tissue
from untreated rats or commercial bird of prey diet)
ad libitum. Nominal CPN concentrations in the formulated
diets were 0.15, 0.75 and 1.5 µg/g food wet weight, and
measured concentrations averaged 94 …
