Is it true that Rodenticides cause secondary poisoning in wildlife?
Yes. Multiple peer-reviewed reviews and reference sources state that rodenticides, especially anticoagulants, cause secondary poisoning in non-target predatory and scavenging wildlife. One source notes bromethalin is not thought to cause secondary poisoning, a compound-specific exception.
