Safety and efficacy of a feed additive consisting of Lentilactobacillus buchneri DSM 32650 as a feed additive for all animal species (BioCC OÜ).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Lentilactobacillus buchneri DSM 32650 as a technological feed additive (functional group: silage additive) for all animal species. The additive is intended to improve the production of silage at a proposed application rate of 1 × 108 colony‐forming units (CFU)/kg fresh material. The bacterial species L. buchneri is considered by the European Food Safety Authority to be suitable for the qualified presumption of safety (QPS) approach. As the identity of the strain has been established and no antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for the target species, consumers and the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be a skin/eye irritant or a skin sensitiser. Given the proteinaceous nature of the active agent, the additive should be considered a respiratory sensitiser. The FEEDAP Panel concluded that Lentilactobacillus buchneri DSM 32650 at a minimum concentration of 1 × 108 CFU/kg fresh material may extend the aerobic stability of silage from easy and moderately difficult to ensile fresh material with a dry matter content ranging from 28% to 45%.
