There have been reports in the media and articles written of animal deaths due to the Elanco (formerly Bayer) brand flea and tick collar, Seresto. On June 15th, Elanco CEO Jeff Simmons appeared before the House of Representatives Subcommittee on Economic and Consumer Policy. Elanco is standing by the collar due to more than 80 safety, toxicity, and efficacy studies. Seresto is sold worldwide in more than 80 countries, and Seresto was approved by the EPA based on the results of said testing.

From Executive Vice President of Elanco U.S. Pet Health, Bobby Modi, “There is no evidence in the scientific evaluation conducted for registration purposes or in the regularly reviewed pharmacovigilance data to suggest a recall of Seresto is warranted, nor has one been requested, or even suggested, by any regulatory agency.”

“Incident reports are collected and reported without regard to actual causation by the product, providing a raw number starting point which must be further evaluated using an internationally accepted standard method of scientific analysis. Based on those analyses, our pharmacovigilance team has not identified any deaths caused by Seresto’s active ingredients.”

Metcalf 107 Animal Clinic has been selling Seresto collars since 2015, and we have not seen or heard of any adverse health reactions due to collar use. Please contact us with questions or concerns.
