Multiple studies have found Seresto collars to be safe for pets and their owners.

In its own press release, Elanco emphasized that the collars could continue to be sold, saying the "comprehensive, multi-year review by the EPA confirms Seresto continues to meet EPA standards for product registration; data affirms the safety profile of the product."

Seresto class action claims dangers of flea and tick collars well documented, lawsuit states. In June, a congressional subcommittee released a report recommending Seresto flea and tick collars be removed from the marketplace following an investigation into its harms, the lawsuit explains.

A friend had one on her dog and we decided to give it a try because nothing else has worked that we have tried. Within 24 hours the fleas were falling off ot the dogs. While it is pricey its definitly worth the price because it works and has had no harsh effects on the dogs for the few months they have had it on.

Seresto had the most complaints about pet harm and deaths The EPA, which worked with the Food and Drug Administration to conduct the analysis, said that they were unable to get enough information from data that Elanco submitted to determine whether Seresto played a role in most death reports.

Things to look for include:

• Redness or irritation around the collar site.
• Alopecia (hair loss) around where the collar sits.
• Temporary reduced appetite after applying the collar.
• Stomach issues (vomiting or diarrhea)
• Other noticeable changes in behavior such as excessive scratching at the collar, restlessness, or agitation.

More commonly reported adverse events inude itching for dogs and hair changes near the collar application site for cats. Less common, but more serious reported adverse events, include neurological symptoms, such as convulsions or ataxia.

However, some pet owners have pointed to the collars as the reason their dogs have suffered from lethargy, loss of motor functions, skin problems, and seizures. "My takeaway is that it should be looked into," says Elizabeth Trepp, DVM.

Serrated edges are blades that have some kind of toothed or saw-like edge ground into the cutting surface. These are intended to be used much like a small saw with a back-and-forth motion. They're great for cutting through belts and ropes, fabric and various other textured materials.

Seresto is just one product connected to major concerns about pet and human safety. In October 2022, the EPA announced it would ban flea and tick collars containing the chemical tetrachlorvinphos, which has been linked to neurological damage in children.

Yes. Seresto® kills existing fleas within 24 hours of applying the collar. New adult fleas are killed within 2 hours for the next 8 months.

Tina Wismer, medical director at the ASPCA Animal Poison Control Center and a toxicology consultant for VIN, said, “Looking at these reports, these are very random things, ranging from ruptured eardrums - which I can't make fit really at all - to liver failure, to heart problems, to kidney failure.

Seresto™ Collars They are made of plastic impregnated with insecticides that are released over time and coat the animal's fur. The active ingredients are imidacloprid (10%) and flumethrin (4.5%).

“We're disappointed the EPA didn't cancel Seresto collars, but it's heartening that they're alerting pet owners to the troubling risks linked to the product,” Nathan Donley, environmental health science director at the Center for Biological Diversity, says in a statement.
