AMCA Response To Study Linking Pyrethroid Exposure to Increased Cardiovascular Mortality
A recent study, “Association Between Exposure to Pyrethroid Insecticides and Risk of All-Cause and Cause-Specific Mortality in General U.S. Adult Population (Wei Bao,MD, PhD; Buyun Liu, MD, PhD; DerekW. Simonsen; Hans-Joachim Lehmler, PhD from the University of Iowa College of Public Health).” published online in December 30, 2019 in the Journal of the American Medical Association Internal Medicine purports to demonstrate a link between pyrethroid exposure and increased mortality from cardiovascular disease. 

The Pyrethroid Working Group, an industry alliance comprised of the following companies: AMVAC Chemical; BASF Corporation; Bayer CropScience; FMC Corporation; Syngenta Crop Protection; and Valent U.S.A. LLC., reviewed the article and provided a preliminary rebuttal, whose points are posted below. 

  • The analysis did not account for family history of cardiovascular disease – even though genetics represent one of the most significant factors for CVD. 

  • The study relied on self-reporting for key variables that are known to contribute to CVD-related mortality, such as smoking, alcohol consumption and physical activity. Potential recall biases in self-assessments such as these can severely impact results. 

  • There was no definitive exposure determination in the study. The metabolite used as an indicator is also found in the environment as a plant and environmental degradate and is not itself of concern. 

  • The determination was also based on a single urine spot sample, which cannot support conclusions on long-term exposure and does not adjust for factors such as body weight and sex. 
  • The study results do not align with the significant body of evidence that does not show these effects, even at extremely high exposure levels.

The fact is pyrethroids are registered by the EPA after careful consideration of the potential environmental and human effects of these products. The registration of all pesticide products undergoes regular review every 15 years (and the pyrethroids are undergoing a 15-year review now) to refine risk assessments in light of current data. To date, the overwhelming preponderance of evidence demonstrates that pyrethroids pose minimal risk to humans if used according to label specifications. 

In addition, the AMCA also has scientific experts in experimental design and statistical inference reviewing the study to further comment on the study. The AMCA will post additional information as it becomes available.
ESA Subcommittee Update
In 2019, the AMCA ESA subcommittee was closely monitoring the submission of two petitions to the United States FWS for the listing of the Bethany Beach Firefly (Delaware) and the Gulf Coast Solitary bee (Florida and Alabama) under the Endangered Species act. As a first step in the listing process, the USFWS assesses the merits of the petition and then decides whether action may or may not be warranted. Unfortunately, both petitions contained inaccurate information about the operations and practices of mosquito control organizations where these two species are found.

The AMCA ESA subcommittee and Technical Advisor Joe Conlon drafted a series of letters to correct the record with regards to mosquito control operations. In December of 2019, both petitions were determined to warrant further action. For the Bethany Beach Firefly and Gulf Coast Solitary Bee, the endangered species listing process has now begun. Encouragingly, the AMCA was able to correct the inaccuracies in at least one petition. As the USFWS stated, “The petitioner claimed that private and public land managers in Florida counties where the Gulf Coast solitary bee occurs regularly apply pesticides to standing water to control mosquito larvae using spraying methods (Hunsberger 2013, p. 82) and may use spraying techniques to control adults in Okaloosa County (Okaloosa County 2015, p. 1). However, a letter from the American Mosquito Control Association (2019, pp. 1–2) clarified that aerial control applications for mosquito larvae are not conducted in Okaloosa, Santa Rosa, and Walton counties and spraying for adults in Okaloosa County is only conducted when a public health emergency has been declared. The letter further indicated that larval mosquito applications are unlikely to be conducted in the same habitat as the bee and host plant.”

The recognition of the AMCA’s letter at such an early stage of the listing process (i.e. before solicitation of public comments) is a positive development. Petitions and responses from the USFWS become public record. It is important to correct misinformation before it becomes a “fact” and in the case of the Gulf Coast Solitary bee this outcome was achieved. The ESA subcommittee remains focused on providing accurate information to regulators about mosquito control practices.

In another endangered species act development, the USFWS has published a proposal for recovery of the Rusty Patched Bumblebee. For those who are not familiar with this listing, in 2017 this species became the first bumblebee to be listed under the ESA. In essence, the recovery plan would see this species restored to many parts of its former range, possibly through reintroductions. The plan would also determine “pesticide load” as a threshold for determining whether a population of this bee is “healthy”. Many details about the plan remain undetermined. The USFWS is soliciting public comments on this plan until Feb. 24th. The ESA subcommittee is closely examining the implications of this plan for mosquito control agencies throughout the Northeastern, Mid-Atlantic and Midwestern states and will prepare comments if necessary.
