Bayer Seresto Flea Collar Lawsuit

Consumer Protection Attorney California

Bayer Seresto Flea Collar Linked to Almost 1,700 Pet Deaths

Seresto, developed by Bayer and now sold by Elanco, works by releasing small amounts of pesticide onto the animal for months at a time. The pesticide is supposed to kill fleas, ticks, and other pests but be safe for cats and dogs.

Thousands of pets are being harmed, according to federal documents obtained through a public records request from the Center for Biological Diversity, a nonprofit organization that watchdogs the EPA as part of its work to protect endangered species. The center provided the documents to the Midwest Center for Investigative Reporting.

Since Seresto flea and tick collars were introduced in 2012, the EPA has received incident reports of at least 1,698 related pet deaths. Overall, through June 2020, the agency has received more than 75,000 incident reports related to the collars, including nearly 1,000 involving human harm.

We are only interested in Bayer Seresto claims that arose in California.

It’s worth noting that Bayer, the company that owns Seresto, also owns Monsanto, the company that produces the controversial, potentially-carcinogenic, glyphosate-based herbicide Roundup. Various cities have banned glyphosate, and more than 11,000 people who developed cancer after using Roundup have filed lawsuits against the company.

The U.S. Environmental Protection Agency (EPA) has received incident reports of at least 1,698 related pet deaths related to Bayer Seresto flea collars.
