Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of the authorisation of Enterococcus lactis NCIMB 11181 (Lactiferm®) as a zootechnical additive for weaned piglets, calves for fattening and calves for rearing. The product under assessment is based on a strain originally identified as Enterococcus faecium. During the current assessment, the active agent has been reclassified as Enterococcus lactis. The additive currently authorised is marketed in two formulations: Lactiferm Basic 50 (a solid formulation to be used in feed), and Lactiferm WS200 (a solid ‘water‐soluble’ formulation to be used in water for drinking). The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. The Panel concludes that the use of Lactiferm® under the authorised conditions of use remains safe for the target species (calves up to 6 months and weaned piglets up to 35 kg), consumers and the environment. The Lactiferm WS200 formulation of the additive is not irritant to skin or eyes. Owing to the proteinaceous nature of the active agent, both formulations of the additive are considered respiratory sensitisers. It is not possible to conclude on the irritating potential for skin and eyes of the Lactiferm Basic 50 formulation or on the potential of both forms of the additive to cause skin sensitisation. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
