19. Provide supplemental information here

O - Unclassifiable/unassessable Reported application site disorders may occur in sensitive animals after product application. They are usually mild and transient. Signs are consistent. Time to onset is unknown. Further, unspecified liver condition and later reported 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 serious 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. However, in this case, unspecified liver condition and death reported long time after removal of the collar. Thus, they are not product related. Time to onset is too long. Considering limited information (e.g. animal details, state of health and necropsy report) and overall aspects, a product relation to the case is unassessable.
