Prevent the Use of Warfarin to Poison Wildlife and Damage our Environment

This petition had 2,638 supporters

The Texas Department of Agriculture has adopted an administrative rule to allow for the use of the anticoagulant warfarin to poison feral hogs in Texas. This rule was adopted as an emergency provision, circumventing the public comment process.

The use of this poison, marketed as “Kaput Feral Hog Lures,” is unacceptable, unethical, and is an environmental threat to Texans. We urge the department to repeal this rule immediately.

Using Warfarin to poison feral hogs endangers Texas wildlife, people, livestock, and pets. According to product data and usage instructions: 

  • “Warfarin has been clearly established as a human teratogen, as it causes birth defects in the offspring of women receiving clinical doses of the compound during any trimester of pregnancy.”
  • Certain questions about the toxicity of warfarin to fish remain.
  • No study has been performed to show that Warfarin will not adversely affect endangered or threatened species.
  • According to the usage instructions: “This product may be toxic to fish, birds and other wildlife. Dogs and other predatory and scavenging mammals and birds might be poisoned if they feed upon animals that have eaten the bait.”

Placing Warfarin in the proposed baiting locations threatens our environment.

  • The proposed application sites are in or near probable resting areas for hogs, including brush along streams, but according to the manufacturer: “Do not apply this product directly to water, to areas where surface water is present or to intertidal areas below the mean high-water mark. Do not contaminate water when disposing of equipment wash waters.”

Using Warfarin to poison feral hogs or any intelligent animal is inhumane. 

  • Warfarin is not a fast-acting poison. A pig will show signs of illness within a few days and will suffer from the effects for 7-9 days. During that time the animal will endure extensive internal and external bleeding and pain.
  • Commissioner Miller claimed warfarin has been used in Australia without ill effects, however, that country has banned the use of the warfarin to reduce the feral hog population because it is inhumane. The Australian Invasive Animals Cooperative Research Center determined  that poison is the least humane method of controlling feral hog populations,  even when compared to hunting the hogs from helicopters.  

This Administrative rule is against the Texas Constitution.

Texas Department of Agriculture and Commissioner Sid Miller have overstepped the bounds of their authority and misused the “emergency action” mechanism to approve an administrative rule that is not supported by the people of the State of Texas; this action is not approved by animal rights advocates, environmental protection advocates, or Texas hunters.

We demand that this rule be immediately and unequivocally repealed before permanent damage is caused!
