If you can’t porkchop ’em, poison ’em

The war on feral hogs enters a new phase.

At a Feb. 21 news conference in Austin, Texas Agriculture Commissioner Sid Miller announced the agency had issued a rule that would allow Kaput Feral Hog Bait, a pesticide containing the anticoagulant warfarin as its active ingredient, to be used in the control of feral hogs. The emergency rule, issued Feb. 6, makes Texas the first and, so far, only state to adopt regulations allowing the use of a lethal toxicant – poison – to control the invasive swine.

Miller, who as a member of the Texas Legislature in 2011 sponsored a successful bill allowing aerial gunning of feral hogs by private citizens with the permission of landowners, trumpeted the new rule as a significant advance in the state’s ongoing war against feral hogs, which compete with native wildlife, carry and transmit diseases such as brucellosis, and annually cause tens of millions of dollars in damage to property, including an estimated $50 million in annual losses to agriculture.

“I am pleased to announce that the ‘feral hog apocalypse’ may be within Texans’ reach with the introduction of Kaput’s hog lure,” Miller said.

Miller’s action was made possible by the U.S. Environmental Protection Agency’s conditional registration last month of Kaput Feral Hog Bait under the federal statutes governing pesticide use across the country. Kaput, the brand name of pesticides produced by Colorado-based Scimetrics Ltd. Corp., is the first and, so far, only toxicant approved by federal authorities for use in feral-hog control.

Warfarin, laced in prepared baits designed to be eaten by feral hogs, is toxic to pigs in the same way that it is lethal to rats, mice and other rodents for which the substance has been used as a toxicant for more than 60 years. Warfarin has therapeutic uses – it is one of the most common medications taken by humans as a blood-clot preventive. But ingested in sufficient quantities by some mammals, warfarin triggers fatal internal hemorrhaging.

Warfarin’s effects are anything but therapeutic in pigs. Feral hogs’ physiology makes them susceptible to warfarin’s toxic effects at a much lower dose than almost any other animal, research has shown. The percentage of warfarin the Kaput Feral Hog Bait approved by EPA is 0.005 percent by weight – five times lower than the 0.025 percent warfarin by weight used in rats/mice baits.

The poison has proven very effective at killing feral hogs, according to research conducted in Texas by Genesis Labs, a sister company of Scimetrics.

[…]

To limit exposure of non-target species such as deer, raccoons, birds and other that might ingest the baits, protocols for distributing it mandate use of a specially designed feeder with a heavy “guillotine” door that must be lifted to access the bait. Feral hogs have little trouble using their stout snouts to lift the door, while the door’s weight and mode of operation stymies most other wildlife.

Additionally, use of the pig poison in Texas will be restricted. Under the rule change announced by Miller, the warfarin-based bait is classified as a “state-limited-use pesticide,” and it can be purchased and used only by state-licensed pesticide applicators.

Landowners or others who want to use the hog toxicant on property in Texas and who do not hold the required license will have to hire a licensed applicator to legally set up the approved bait dispensers and distribute the bait. That almost certainly will limit its use.

Some Texans would rather it not be used at all.

In the wake of Miller’s announcement, the Texas Hog Hunters Association initiated an online petition to have the rule revoked. The group cites concerns about the potential human health effects of eating feral hogs that have ingested the warfarin-infused baits as well as questions about collateral damage to non-target species such as deer or domestic dogs that ingest treated baits and possible secondary poisoning of animals and protected birds such as hawks and eagles.

As of early Saturday, the online petition at change.org had garnered 10,400 supporters.

Texas Department of Agriculture statements counter those concerns, noting the low levels of warfarin in hogs that consume the baits pose little threat to humans, especially if they avoid eating the animal’s liver, where most of the warfarin will be concentrated. Also, the bait contains a blue dye that transfers that color to the fatty tissues of hogs. Hunters taking a hog and finding blue-tinted fat can decline to eat the animal.

Here’s the petition in question. It turns out that these hunting groups did more than just create a petition, and they got some results.

A Waco-area feral hog processor on Monday said he was racing to get a bill filed that would shoot down Texas Agriculture Commissioner Sid Miller’s call for a “hog apocalypse” through use of a poisonous bait.

Will Herring, owner of Wild Boar Meats, last week won a court order temporarily halting Miller’s Feb. 21 rule allowing use of “Kaput Feral Hog Lure,” arguing the measure would spook pet food companies he sells to and put him out of business. Herring said he’d since secured Rep. Kyle Kacal, R-Bryan, as primary sponsor for legislation that would require study of chemicals before they are approved. The deadline to file bills for the current state legislative session is Friday.

“All our bill says is, ‘Let’s have a state agency and/or state educational institution study this poison and any other poison before it before it becomes legal,’” Herring said from Austin, where he was recruiting state lawmakers to back the bill. “There’s not one public study, and by public study I mean a study available to the public, that has looked at using the product Kaput to poison feral hogs.”

[…]

Herring said he was processing as many as 5,000 hogs a month and was getting ready to break ground on a new facility when Miller announced a rule that could potentially put he and other wild hog processors out of business.

“We have not developed a way to test for it, nor have we developed a way to inactivate it,” Herring said. “If someone said, ‘Look, I only want to buy warfarin-free wild hog meat,’ we do not know a way that we could guarantee that. And that’s a problem to me.

“It’s not just me that’s concerned about this,” Herring added. “I only do the pet food business. There’s a couple of companies that deal with the human consumption business, and it’s the same issue.”

Herring last Wednesday filed a lawsuit against Miller’s rule, with the Texas Hog Hunters Association and Environmental Defense Fund filing supporting briefs. State District Judge Jan Soifer in Austin on Thursday issued a temporary restraining order stopping Kaput use in Texas until March 30, saying the TDA did not follow the Texas Administrative Procedures Act and agreeing that allowing Kaput would cause “immediate and irreparable harm” to Wild Boar Meats.

All right then. I have some sympathy for the hunters here, because introducing poison into the environment, even in a fairly controlled fashion like this, carries a higher level of risk. Even with the protocols in place, there’s no way to fully prevent unintended consequences of this. It should be noted that this isn’t the first attempt at poisoning the pigs, but it is the first one with an EPA-approved toxin. We’ll see how this plays out in court, and I’ll keep my eyes open for an anti-warfarin bill in the Lege; as of yesterday, I didn’t see anything authored by Rep. Kacal that sounds like this.

    I don’t care if the hog processors get hurt or not. There’s no way they are going to get enough hogs to cause a dent in the population. And, why should the business concerns of a couple of processors take priority over the needs of thousands of land owners whose property is being torn up by hogs?

  2. Bill Daniels says:

    @ Ross:

    I replaced “hog processors” with “transgender people” in your post and read it that way.

  3. Terrance Jewett says:

    @Bill
    So transgenders are ruining your property so you want to kill them? There’s no way they are going to get enough transgender people to cause a dent in the population.
    Your hatred has no bounds.

  4. Bill Daniels says:

    Terrance,

    Lighten up, Francis. You have no sense of humor, or, in this case, sense of irony. Both the bathroom thing and the feral hog problem have a basic commonality. Ross is siding with the vast majority of Texans on the hog issue, and he’s willing to put their needs ahead of the needs of the minority, the processors that sell meat to pet food companies.

    I’m not advocating killing anyone. Geez.

    @ Terrance,

    For what it’s worth, I don’t support SB6, and I do support gay marriage.

  6. paul a kubosh says:

    I didn’t want to talk about men peeing in girls restrooms in the City of Houston and I don’t want to talk about it in the State Legislature. I think the Supreme Court decision on Gay Marriage was legally correct. Finally I don’t support the recreational use of Pot by Pot Heads. Sorry Bill. 🙂
