Death

19. Provide supplemental information here

O - Unclassifiable/unassessable The reported serious signs such as breast cancer and death are not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause such signs either. An overdose of 5 collars around the neck was investigated in adult cats and dogs for an 8 months period and in 10 week old kittens and 7 week old puppies for a 6 months period without causing serious signs. This is supported by the extremely low systemic exposure with imidacloprid and flumethrin, particularly during the first week after application and also thereafter. No signs of anaphylaxis reported which would have occurred in close proximity to the collar application. Death may be consequence of reported breast cancer. Besides, the intent of the call was to inquire about product use in general and not to report this event. Considering some information missing (weight, health status, time to onset and no necropsy was performed), product involvement is not likely, however due to limited information case is considered unassessable.
