DEAR DR. FOX: Your article about neonicotinoid insecticides is much appreciated. I want to inform you and your readers that the American Bird Conservancy is disappointed in the EPA's decision to deny a 2017 petition to reclassify pesticide-coated seeds. The announced rulemaking does not go far enough.

Pesticide-coated seeds are a major threat to birds, but are currently exempt from regulatory safeguards. Sadly, the EPA has announced it does not plan for that to change anytime soon. Pesticide-coated seeds fall through a loophole in the Federal Insecticide, Fungicide and Rodenticide Act called the Treated Articles Exemption. The exemption allows dangerous chemicals to be used without any protections for wildlife or water quality.
Nearly 100% of corn and roughly 50% of soybeans grown in the United States are the products of pesticide-coated seeds. This issue has received attention from agencies and congresspeople, namely Sen. Cory Booker of New Jersey, who has asked for better regulation of this use of pesticides.
Concerningly, seed coatings are the main use of neurotoxic, bird-killing neonicotinoid insecticides ("neonics"). Birds that ingest coated seeds may die, and when the pesticide sloughs off and infects soil and water, it indiscriminately kills non-target invertebrates. ABC found that a single seed coated with neonicotinoid insecticide is enough to kill a songbird. Even more troublingly, most of the pesticide (as much as 97%) leaves the seed, blanketing surrounding lands as bee-killing dust or leaching into the local ecosystem. Once in soil and water, it indiscriminately kills insects and aquatic invertebrates, depriving birds of important food sources. Barn swallows are among the species most heavily impacted by insect loss; 40% have disappeared in the last five decades.
Soybeans and corn grown with coated seeds show negligible benefit to crop yield, but farmers who do not want to use these seeds are given little choice; most corn and soybean seeds come pretreated, and farmers have to special-order untreated seeds. The coatings come at a huge markup, making them lucrative profit opportunities for seed distributors and pesticide manufacturers.
Changing the special status of coated seeds is a long overdue step for wildlife conservation. We are facing a catastrophic loss of birds in North America: There are nearly 3 billion fewer than in 1970, with prey loss and poisoning as major contributors.
ABC urges the EPA to close this loophole. Moving treated seeds within the grasp of scientific regulation would benefit birds and humans for decades to come. Exempting them puts us all in danger. -- Hardy Kern, Director of Government Relations, American Bird Conservancy; Washington, D.C.
DEAR H.K.: I applaud what your organization is doing to help save the birds and the ecosystems upon which they -- and we -- depend. These substances are widely used in the U.S. agriculture industry and are given to companion animals to control fleas and ticks. But they are rarely, to my knowledge, questioned by veterinarians while being constantly advertised to pet owners on TV.
The great irony is that in Europe, these pesticides are condemned for agricultural use (with emergency exceptions), but not for use on companion animals! Concerns are now being voiced by some of my veterinary colleagues in the U.K.
Studies show that chemicals in topical flea treatments pollute water and can cause seizures and other health issues in companion animals, as I document on my website (drfoxonehealth.com/post/companion-animal-risks-of-flea-and-tick-insecticides). The American Veterinary Medical Association needs to step forward on this animal and environmental health issue. The political and economic power of the pesticide manufacturers must be confronted by responsible legislators and regulatory agencies. The use of these chemicals in the court of science-informed public opinion should be judged as a crime against nature -- and therefore, from a One Health perspective, a crime against humanity.
