Abstract
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 the authorisation of vitamin K(3) in the form of menadione sodium bisulphite (MSB) and menadione nicotinamide bisulphite (MNB) as nutritional feed additives. The additives MSB (3a710) and MNB (3a711) are currently authorised for use in all animal species. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the use of vitamin K(3) in the form of MSB and MNB remains safe for the target animals, consumer and for the environment under the approved conditions of the authorisation. Regarding user safety, the Panel concluded that exposure by any route is considered a risk and should be minimised. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
