# Safety and efficacy of a feed additive consisting of Enterococcus lactis NCIMB 10415 for all animal species (Agri‐King, Inc.)

## TL;DR

This study evaluates the safety and effectiveness of using Enterococcus lactis NCIMB 10415 as a feed additive to improve silage quality for all animal species.

## Contribution

The study confirms the safety of Enterococcus lactis NCIMB 10415 for animals, consumers, and the environment, and its potential to improve silage fermentation.

## Key findings

- E. lactis NCIMB 10415 is safe for all animal species and does not pose a risk to consumers or the environment.
- The additive has the potential to improve silage production and fermentation quality when used at a minimum level of 1 × 108 CFU/kg.
- The additive is irritant to eyes and a skin and respiratory sensitiser, posing a risk to users upon exposure.

## Abstract

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on Enterococcus lactis NCIMB 10415 when used as a technological additive to improve ensiling of all types of fresh plant material for all animal species at a proposed minimum level of 1 × 108 colony forming units (CFU)/kg fresh plant material. The strain NCIMB 10415 was unambiguously identified as Enterococcus lactis, found not to belong to the hospital‐associated clade of Enterococcus faecium and acquired antimicrobial resistance genes were not detected. Consequently, the FEEDAP Panel concluded that E. lactis NCIMB 10415 is safe for all animal species, for consumers of products from animals fed with the treated silage and for the environment. Regarding the safety for the user, the additive is considered irritant to eyes and a skin and respiratory sensitiser. Therefore, any exposure is considered a risk. The FEEDAP Panel concluded that the addition of E. lactis NCIMB 10415 at a minimum level of 1 × 108 CFU/kg to fresh plant material has the potential to improve the production and fermentation quality of silage made from all types of plant materials.
