　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of authorisation of a preparation containing a smoke flavouring extract for cats and dogs. The applicant provided data demonstrating that the additive currently on the market does not fully comply with the conditions of authorisation, but with newly proposed specifications based on different analytical methods. Considering that the additive under assessment contains benzofuran and styrene, for which a potential concern for genotoxicity has been identified, and that the whole mixture raises a potential concern for genotoxicity, additional data would be needed to complete the assessment. Therefore, the FEEDAP Panel is not in the position to conclude on the safety for cats and dogs. The additive is authorised for use in feed for cats and dogs, and therefore, there is no need to perform an assessment of the safety for the consumer and the environment. Regarding user safety, the additive should be considered as irritant to skin and eyes, and as a dermal and respiratory sensitiser. When handling the additive, exposure of unprotected users to potential genotoxic substances may occur. Therefore, to reduce the risk, the exposure of the users should be minimised. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
