Safety and efficacy of a feed additive consisting of Lactococcus lactis DSM 34262 as an acidity regulator additive for all animal species (Lactosan GmbH & Co.KG)

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on Lactococcus lactis DSM 34262 when used as a technological additive (acidity regulator) in feed for all animal species. The additive is intended to be incorporated into feed materials of plant origin with high moisture content (dry matter range between 25% and 40%). The bacterial species L. lactis is considered by EFSA to be suitable for the qualified presumption of safety (QPS) approach to safety assessment. The identity of the strain has been clearly established and it did not show acquired resistance to antibiotics of human and veterinary importance. The FEEDAP Panel concluded that the preparation of L. lactis DSM 34262 is safe for the target species, consumers and the environment. Regarding user safety, the additive should be considered as a skin and respiratory sensitiser. Exposure of users via dermal and respiratory routes is considered a risk. The FEEDAP Panel concluded that incorporation of L. lactis DSM 34262 at a minimum concentration of 1.0 × 108 CFU/kg feed material has the potential to reduce the pH of feed materials of plant origin at the proposed conditions of use.
