Seresto Flea & Tick Collar Linked to 1,700 Pet Deaths, 1000 Human Illnesses

Seresto Flea & Tick Collar Linked to 1,700 Pet Deaths, 1000 Human Illnesses

March 4, 2021 — Seresto Flea & Tick Collars have been linked to reports of nearly 1,700 pet deaths and 1,000 human illnesses, according to an investigation by USA Today.

The investigation was led by researchers with the Midwest Center for Investigative Reporting.

Seresto Flea & Tick Collars are designed to release small amounts of pesticides onto the animal for months at at time, which is supposed to kill fleas and ticks, but not harm the pet or people who touch the pet.

Instead, investigators found that the EPA has received reports of at least 1,698 pet deaths associated with Seresto flea collars, which were developed by Bayer and now sold by Elanco, since the collars were introduced in 2012.

As of June 2020, the EPA had also received repots of 1,000 human illnesses linked to the collars, ranging from rashes and hives to neurological symptoms.

In one report, a 12 year-old boy was hospitalized with seizures and vomiting after sleeping in bed with a dog who was wearing the collar.

A spokesperson for the manufacturer, Elanco, said that worldwide data shows that 1 in 568 users of the Seresto collar have an incident, but most are minor, and reports do not necessarily mean that the product caused the problem.
