Poison Control Updates – Rodenticides

Untitled1Poison Control Updates – Rodenticides


Poison Control is serious business when you have pets or children in your household.  Recent regulation changes by the EPA required that manufacturers of rodenticides for consumer use stop using second-generation or long-acting anticoagulants.  Manufacturers must also contain bait in tamper-resistant bait stations.  Pellets and other forms of bail that cannot be secured are prohibited.


The manufacturer of d-CON products has not complied with the new EPA regulations.  The new generation of rodenticides currently on the market often uses bromethalin, a toxin for which there is no antidote.  There is also no current test to detect it – except for a postmortem exam


Bromethalin rodenticide toxicity, more commonly referred to as rat poisoning, occurs when a dog becomes exposed to the chemical bromethalin, a toxic substance that is found in a variety of rat and mice poisons. Ingestion of bromethalin can lead to an increased pressure of cerebrospinal fluid (the liquid within the membrane of the skull that the brain essentially floats in) and cerebral edema (the accumulation of excess water in the brain). A variety of neurological-based symptoms can result from this, including muscle tremors, seizures, and impaired movement.


While other species may be affected by the accidental ingestion of rat poison, cats and dogs are most frequently prone to this condition.


pupCommon symptoms of toxic exposure in dogs include loss of appetite, impaired movement, paralysis of the animal’s hind limbs, slight muscle tremors, generalized seizures, and a depression of the central nervous system. Ingestion of extremely high doses may cause a sudden onset of muscle tremors, and even seizures.
