(Beyond Pesticides, June 6, 2025) Published in Environmental Pollution, a study of commercial dry pet products finds dietary pesticide residues in dog and cat food, âhighlighting the urgent need for improved regulatory frameworks to address the presence of non-approved pesticides in pet food.â Additionally, the researchers point out: âCurrent regulatory frameworks primarily assess the toxicity of individual pesticide compounds, yet real-world exposure involves complex mixtures that may lead to additive or synergistic effects. The presence of multiple residues in a single sample suggests that companion animals may be subjected to combined toxicological burdens that are not yet fully understood.â (See studies here, here, and here.) The researchers assess pesticide contamination, and their associated toxicological risks, in 83 total food products for dogs (43) and cats (40). Of the foods tested, the researchers found a total of 51 pesticides, many of which are banned in the European Union (EU), including 47% fungicides and 37% insecticides. âPesticide residues in pet food pose potential risks to animal health, yet their occurrence and dietary exposure in companion animals remain largely unexplored,â the authors state. They continue: âTo our knowledge, this is one of the first comprehensive investigations assessing both pesticide prevalence and potential dietary […]

(Beyond Pesticides, February 11, 2025) In a Science of The Total Environment study, scientists test over 100 blue tit (Cyanistes caeruleus) and great tit (Parus major) birdsâ nests for pesticide residues in comparison with the number of dead offspring and unhatched eggs within the nest. Fur-lined nests, from animals treated with ectoparasitic chemicals, expose birds to compounds that can impact reproductive success. The authors found fipronil, a phenyl pyrazole insecticide, in all nests, with the majority also containing the neonicotinoid insecticide imidacloprid and synthetic pyrethroid insecticide permethrin. The data shows higher insecticide levels are linked to increased offspring mortality and threaten biodiversity. This study highlights an important exposure route that is overlooked. âAlthough not all bird species use fur for nest building, a substantial number do, especially cavity-nesting species,â the researchers share. âPrevious research found that 74% of studied woodland bird species in central Europe incorporated fur into their nests.â Many bird species in the U.S. also line their nests with fur, such as black-capped chickadees, tufted titmice, and chipping sparrows. While there is a wide body of science showing reproductive effects from pesticides, the researchers highlight the studyâs novel design, saying, âTo the best of our knowledge, no previous […]

(Beyond Pesticides, May 8-9, 2024) In its proposal on mushrooms and pet food, the U.S. Department of Agricultureâs (USDA) National Organic Program is following up on recommendations of the National Organic Standards Board (NOSB) to ensure that two areas of organic production are clarified and in compliance with the Organic Foods Production Act (OFPA). The notice raises questions of standards that ultimately grow the organic market while ensuring that the USDA organic label is backed by standards that have integrity and garner the publicâs trust. In this spirit, Beyond Pesticides participates in the NOSB review/recommendation process and USDA rulemaking through public comments. [Note: Beyond Pesticides has served on the NOSB for a five-year term (2010-2015) and urges other environmental organization representatives to consider self-nominating for service on the board.] The issues relating to clear standards for mushrooms and pet food have been before the NOSB and in discussion for some time as a part of ongoing efforts to ensure continuous improvement of standards governing the organic sector. While virtually all in the organic community and industry agree that the USDA proposals are needed and long overdue, Beyond Pesticides points to problems in the proposed rule that need correcting: (i) Re.

(Beyond Pesticides, March 11, 2024) Inside a recent disagreement between the Office of the Inspector (OIG) and the U.S. Environmental Protection Agencyâs (EPA) Office of Pesticide Programs (OPP) on the agencyâs review of pet flea and tick collarsâleading to thousands of deaths and poisoningsâis a basic question of the adequacy of pesticide regulation. The disagreement is over the cause of 105,354 incident reports, including 3,000 pet deaths and nearly 900 reports of human injury, and the February 2025 OIG reportâs conclusion that â[EPA] has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.” While the disagreement focuses on a number of EPA process failures, Beyond Pesticides urges that the findings advance the need for the agency to address a key element of chemical mixtures in pesticide products not currently evaluated, potential synergistic effectsâthe increased toxic potency created by pesticide and chemical combinations not captured by assessing product ingredients individually. Key to the dispute is what many see as a foundational failure of EPA to evaluate the effect of pesticide mixtures and full formulations of pesticide end products, a longstanding criticism of the agencyâs pesticide registration process, which focuses on pesticide productsâ active […]

(Beyond Pesticides, March 6, 2024) With over 2,500 pet deaths and 900 reports of adverse effects to people, an Office of Inspector General (OIG) report, published on February 29, 2024, reveals multiple systemic failures by the U.S. Environmental Protection Agencyâs (EPA) Office of Pesticide Programs (OPP), citing inadequate safety reviews of Seresto pet collars. The report, The EPA Needs to Determine Whether Seresto Pet Collars Pose an Unreasonable Risk to Pet Health, concludes, âThe EPAâs response to reported pesticide incidents involving Seresto pet collars has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.â At the time the animal effects made headlines in 2021, the agency defended the productâs registration, telling the media that, despite these incidents, EPA deemed Seresto collars ââeligible for continued registrationâ based on best available science, including incident data… No pesticide is completely without harm, but EPA ensures that there are measures on the product label that reduce risk.ââŻDespite the scathing criticism, EPA maintains the position that it conducted an adequate review of the two active insecticide ingredients in the pet collarsâthe neurotoxic insecticideâŻflumethrin, and the notorious neonicotinoidâŻimidaclopridâproven to have adverse effects on the endocrine system as […]

(Beyond Pesticides, September 29, 2023)Â In unsurprising news, the Environmental Protection Agency (EPA) has reversed itself and decided not to ban a dangerous pesticide: tetrachlorovenphos (TCVP) used in pet flea collars and other flea products. This is despite its own earlier decision to ban TCVP in pet collars and scathing criticism of its methods and conclusions by the courts. First registered in 1966, TCVP belongs to the notoriously toxic organophosphate chemical family and is classified by the World Health Organization as âpossibly carcinogenic to humans.â It was originally registered to Shell Chemical, then to E.I. duPont de Nemours, then to Hartz Mountain Corporation and Fermenta Animal Health Company. Â Early on, it was registered for use on food crops and livestock, but the crop uses were voluntarily de-registered in 1987. It is still widely used on pets and farm animals. In 1995, EPA issued the opinion that âall uses of tetrachlorvinphos, with the exception of oral feed-through larvicide treatment to livestock intended for food use, will not cause unreasonable risk to humans or the environment.â Since then, the agency has contorted itself repeatedly to allow TCVP to remain on the market. There is little research available on TCVPâs human health effects; the […]

(Beyond Pesticides, August 23, 2023) The use of pesticides on pets for fleas and ticks (parasiticides) has been traced to environmental contamination in a study that confirms earlier work both by the authors and internationally, according to researchers Rosemary Perkins, a veterinary surgeon, and David Goulson, PhD at the University of Sussex. The results are published in their recent study, âTo flea or not to flea: survey of UK companion animal ectoparasiticide usage and activities affecting pathways to the environment,â which concludes that, â[T]he potential cumulative impact of parasiticide emissions [into the environment] from many millions of pets treated multiple times each year is of serious concern.â The UK provides an opportunity to pinpoint water contamination from pet use for ectoparasites (e.g., fleas and ticks) of hazardous pesticides since, unlike in the U.S., the country has banned outdoor use of those chemicals commonly detectedâthe insecticides fipronil and imidacloprid (the same neonicotinoid bug killer tied to devastating losses of bees and other organisms). These findings confirm the historical peer reviewed scientific literature and defy the assumption of regulators that home or veterinary use of pesticides do not reach levels of concern for environmental contamination, either through exposure from down-the-drain (DTD) contamination […]

(Beyond Pesticides, August 1, 2023) The U.S. Environmental Protection Agency has announced that it is publishing a decade’s worth of pesticide incident data in a searchable database that will be updated on a monthly basis. The Incident Data System (IDS), with poisoning reports generated mostly from chemical manufacturers, states, a national hotline, and poison control centers, offers information on reported pesticide exposures from accidental poisoning of pets, wildlife, and humans, to pesticide drift, noncompliance, and other pesticide incidents that may be associated with product uses in compliance with label instructions. Tracking this incident data is essential to understanding the risks and damages associated with pesticide use. Â The bulk of the data on incidents is from consumer reports to chemical manufacturers. Chemical companies are required under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Section 6(a)(2) to report incidents: âIf at any time after the registration of a pesticide the registrant has additional factual information regarding unreasonable adverse effects on the environment of the pesticide, the registrant shall submit such information to the Administrator.â The determine of threshold number of incidents required to be reported as a pattern of âunreasonable adverse effectsâ is left to the manufacturers to determine. Through […]

(Beyond Pesticides, May 7, 2020) On April 22, 2020, the Ninth Circuit U.S. Court of Appeals granted the U.S. Environmental Protection Agency (EPA) 90 days to respond to Natural Resources Defense Councilâs (NRDC) petition requesting cancellation of tetrachlorvinphos (TCVP), a toxic organophosphate pesticide in pet products. The order followed the Ninth Circuitâs decision to grant NRDCâs petition for a writ of mandamus (a courtâs order requiring a lower court or public authority to perform its statutory duty) as EPA withheld action to fulfill NRDCâs judicial review of TCVP, for over a decade. A favorable ruling on NRDCâs mandamus petition can influence other petitioners that hope to coerce agency action, especially when public health is at risk. The court states, âRepeatedly, the EPA has kicked the can down the road and betrayed its prior assurances of timely action, even as it has acknowledged that the pesticide poses widespread, serious risks to the neurodevelopmental health of children.â NRDC petitioned EPA to cancel TCVP pesticide registration under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) in April 2009, after studies indicated humans absorb TCVP through contact with pesticide-treated pet products. EPA failed to respond to the initial petition after five years, and NRDC filed a 2014 mandamus requiring […]
