Seresto Flea and Tick Collar Pesticides May Harm Pets Class Action

Can flea and tick collars pose a health hazard to pets and their owners? The complaint for this class action brings suit against Bayer Healthcare, LLC and Elanco Animal Health, Inc., alleging that their Seresto brand flea and tick collars can cause “risk of irritation, rashes, hair loss, gastrointestinal problems, seizures, and even death.”

The class for this action is all persons in the US who bought the products for use and not for resale.

A USA Today March 2021 report that is “based on documents from the Environmental Protection Agency (‘EPA’),” the complaint says, claims that some 75,000 incident reports and 1,698 pet deaths have been associated with Seresto collars. The complaint says, “Of the 75,000 incidents, nearly 1,000 involved human harm.”

The complaint asserts, “The high number of incidents is likely related to the synergistic effect of the two pesticides contained in Seresto Collars: imidacloprid and flumethrin.”

Imidacloprid is part of the class of insecticides most commonly used on crops in the US, in spite of the fact that they have been connected to what the complaint calls “massive die-offs of non-target insects such as bees and butterflies,” the EPA may be reapproving them. While the same chemicals are banned for use on crops in the European Union, they are permitted for use in pet collars. But, the complaint claims, [t]here is growing evidence that mammals can be harmed by these pesticides as well.

As to the second ingredients, the complaint alleges, “Flumethrin, EPA documents show, is only an active ingredient in one product: Seresto Collars.” And, the complaint claims, the two chemicals working together may not be the only problem: “The inert or inactive ingredients in the Products, in combination with Flumenthrin an Imidacloprid may also trigger reactions and/or serious injury.”

The Federal Insecticide, Fungicide and Rodenticide Act requires that the EPA must find that pesticides do not cause “unreasonable effects on the environment” considering both harms and benefits.

Unfortunately, the complaint claims that the information on the Seresto pesticides was provided by Bayer, one of the companies making the product, and most of them involved each one used separately. “However,” the complaint alleges, “a 2012 Bayer study found they have a ‘synergistic effect,’ meaning they are more toxic together on fleas.”

The EPA used this and eight other studies to approve Seresto collars. The California Department of Pesticide Regulation “took issue with the validity of two of the studies[,]” the complaint says, but still approved the collars.

The complaint reproduces some online postings about problems with the Seresto collars and cites individual stories of human reactions when their dogs sleep with them while wearing Seresto collars.

The complaint points out that the packaging for the collars does not include any warnings of possible effects from the collars.
