Excerpts: "...The Pest Management Regulatory Agency (PMRA) has determined that sodium monofluoroacetate is acceptable for continuing registration provided that the mitigation measures specified in the PACR [June 18, 2004 -see below] are implemented. The registrants will be informed by letter of the specific requirements affecting their product registrations and the regulatory options available to comply with this decision."

June 18, 2004. Canada: Re-evaluation of Sodium Monofluoroacetate. The purpose of this document is to solicit public comment for continued use in the provinces of Alberta and Saskatchewan for coyote and wolf control. It is formulated as a solution inside livestock protection collars or as tablets. Collars are attached to goats and sheep. Tablets are placed in small drop baits (usually meat, viscera or chicken heads) and buried beneath snow, leaves, or soil in order to minimize non-target exposure. The PMRA will accept written comments on this proposal up to 45 days from the date of publication of this document. Pest Management Regulatory Agency. Document No. PACR2004-20.

Rationale for US EPA to add Sodium Fluoroacetate to the Toxic Release Inventory

In a 13-week oral study in rats, gavage administration of sodium fluoroacetate (0.02 mg/kg/day) resulted in decreased testis weight and altered spermatogenesis in males (the NOAEL was 0.05 mg/kg/day). In addition, increased heart weight was noted in females and males administered 0.20 mg/kg/day of sodium fluoroacetate. The increase in heart weight, however, was only accompanied by subacute, minimal inflammation (not dose-related). Also, fluorocitrate levels were significantly increased after 4 weeks in males administered 0.50 mg/kg/day and after 13 weeks in both male and female rats administered 0.20 or 0.50 mg/kg/day. The testicular and cardiac effects were reported to be consistent with those noted in the literature.

A case study reported a deliberate ingestion of an unspecified dose of sodium fluroacetate by a healthy female. The woman experienced nausea, vomiting, and abdominal pain 30 minutes after ingestion, with subsequent seizures occurring 60 minutes after the initial onset of symptoms. Neurological examination after 2 weeks revealed severe cerebellar dysfunction. By 18 months, memory disturbances and depressive behavior persisted. Inhalation exposure to unspecified levels of sodium fluoroacetate caused salivation, loss of speech, violent convulsions, and coma in a male worker. The patient ultimately recovered. Neurological effects have also been reported in rats in a 13-week oral study. Four of 20 female rats treated with 0.50 mg/kg/day (the highest dose tested) exhibited convulsions at day 79, with no recurrences for the remainder of the study. An estimated lethal dose of sodium fluoroacetate in humans ranges from 5 to 10 mg/kg.

EPA believes that there is sufficient evidence for listing sodium fluoroacetate on EPCRA section 313 pursuant to EPCRA section 313(d)(2)(B) based on the neurologic, reproductive, and myocardial toxicity data for this chemical.

Measured oral LD 50 values of fluoroacetate in the house sparrow, redwinged blackbird, starling and golden eagle are 3.0, 4.22, 2.37, and 1.25 to 5 mg/kg, respectively. In addition, measured acute toxicity data for mammalian wildlife include an oral LD50 of 0.22 to 0.44 mg/kg for mule deer, an oral LD50 of 1.41 mg/kg for male ferrets, and an oral LD 50 of 0.5 to 1.0 mg/kg for bears. EPA believes that there is sufficient evidence for listing sodium fluoroacetate on EPCRA section 313 pursuant to EPCRA section 313(d)(2)(C) based on the environmental toxicity data for this chemical.

Development and use of 1080 as a predacide and rodenticide occurred in the US in the 1940s, but all registrations were cancelled in 1972 together with those for other predator control agents containing strychnine and sodium cyanide. Registration of livestock protection collars was restored in 1985 and remains the only approved use in the US. 1080 is also used in Mexico and Israel, but the bulk of world usage occurs in New Zealand and, to a lesser extent, Australia. 1080 has been registered in New Zealand since 1964... The use of 1080 in Australia was pioneered in the early 1950s as a rabbit poison in Tasmania. Since this time, 1080 has been approved for use in various States of Australia for the control of various vertebrate pests. Application of 1080 baits is by aerial or ground distribution. It has been estimated that approximately 200 kg of 1080 active ingredient is used in Australia annually.

Sodium fluoroacetate (1080), is a fluorinated carboxylic acid ester with high to very high toxicity to birds and mammals. Once ingested 1080 is metabolised to fluorocitrate. Fluorocitrate interferes with energy production in the Krebs cycle, a metabolic pathway that breaks down carbohydrates to provide energy for normal cell functions. The malfunctioning Krebs cycle results in an accumulation of citrate in the tissue and blood, energy deprivation and death. No antidote to 1080 exists.

Petition Requesting EPA to Issue a Notice of Intent to Cancel the Registrations of M-44 Sodium Cyanide Capsules and Sodium Fluoroacetate. EPA requests public comment during the next 60 days on a petition, and its addendums, received from Sinapu, Public Employees for Environmental Responsibility (PEER), Beyond Pesticides, Forest Guardians, Predator Defense, Western Wildlife Conservancy, Sierra Club, The Rewilding Institute, Animal Defense League of Arizona, and Animal Welfare Institute requesting that the Agency cancel all uses of M-44 sodium cyanide capsules and sodium fluoroacetate (compound 1080). The petitioners claim that sodium cyanide M-44 capsules and compound 1080 cannot perform their intended functions without causing unreasonable adverse effects on the environment and posing an imminent hazard.

(Page 22-23) Furthermore, livestock protection collars can be easily lost or punctured by vegetation or barbed wire. In one study, 107 collars were either inadvertently lost or punctured, while only 57 were pierced by coyotes (Watson 1990). Connolly (1998) suggests that coyotes can bury collars or drag them away from sheep carcasses and that about half of missing collars were not recovered in research studies. Apparently, LPCs routinely go missing which constitutes "imminent harm" to the environment. 7 U.S.C. §136(l). More alarming, the EPA and APHIS rely on individuals to properly dispose of Compound 1080 once a spill has occurred. Livestock producers, who have been trained by licensed applicators, are expected to incinerate or bury everything that has come into contact with Compound 1080. Those that bury the toxicant must do so under three feet of soil (Connolly 1998). The burial site is supposed to be one-half mile from human habitation and away from water sources; no more than 10 collars can be buried at one site and the sites must be ten feet apart from each other (Connolly 1998). Relying on livestock producers to properly dispose of Compound 1080, without any oversight by certified personnel, presents potential problems including the theft or improper disposal that could cause intentional or unintentional human poisonings to occur.

(PAGE 23) In 1989, a newly-hired predator control agent to the Wyoming office of the Wyoming Department of Agriculture found that those officials had hoarded Compound 1080 despite the ban. They sold 1080 to private individuals who used it to poison wildlife, including bald and golden eagles (Robinson 2005). In 1991, the FWS and the EPA raided the offices of the Wyoming Department of Agriculture; the FWS subsequently engaged in a law enforcement action that led to several, copvictions (Ibid.). (FWS's investigative documents involving many defendants attached, Exhibits 7 and 8.) But that would not be the end of illegal poisonings. In 2001, approximately 30 pets were poisoned by 1080 in Grand Junction, Colorado and the investigating police officer, David Palacios, who handled the poisoned animals, experienced, "`flu like symptoms, only 10 times worse"' (Lofholm 4/12/O1). The Grand Junction police and federal investigators were never able to apprehend the culprit who ultimately dumped the poison into the local sewer system (Lofholm 3/15/O1, 4/12/01).

Recordkeeping Requirements for Certified Applicators Using 1080 Collars on Livestock; Renewal of Pesticide Information Collection Activities and Request for Comments. EPA is seeking comments on the following ICR numbers: EPA ICR No. 1249.07, OMB Control No. 2070-0074. ICR status: This ICR is a renewal of an existing ICR that is currently approved by OMB and is due to expire September 30, 2003. Abstract: This ICR affects approximately 75 certified pesticide applicators who utilize 1080 toxic collars for livestock protection. Four states (Montana, New Mexico, South Dakota, and Wyoming) monitor the program, and five pesticide registrants are required to keep records of: (1) Number of collars purchased; (2) number of collars placed on livestock; (3) number of collars punctured or ruptured; (4) apparent cause of puncture or rupture; (5) number of collars lost or unrecovered; (6) number of collars in use and in storage; and (7) location and species data on each animal poisoned as an apparent result of the toxic collar. Applicators maintain records, and the registrants/ lead agencies do monitoring studies and submit the reports. These records are monitored by either the: State lead agencies; EPA regional offices; or the registrants. EPA receives annual monitoring reports from registrants or State lead agencies.

March 15, 1995 na EPA denied request from Texas Department of Agriculture for the use of sodium fluoroacetate on certain mammalian vectors to control gray fox rabies. A notice of receipt of this public health exemption was published in the Federal Register of August 24, 1994 (59 FR 43580), an extension of comment period later published September 8, 1994 (59 FR 46428). The Agency concluded that the proposed vector control program cannot be expected with any degree of certainty to be effective in halting the spread of the epizootic. For this reason, the Agency denied the request for a public health exemption.
