## TL;DR

This paper evaluates the safety and effectiveness of a bacterial additive for improving silage production in animal feed.

## Contribution

The study confirms the safety and efficacy of Loigolactobacillus coryniformis DSM 34345 as a silage additive for all animal species.

## Key findings

- The additive is safe for animals, consumers, and the environment.
- The strain can improve silage production at a minimum concentration of 1 × 108 CFU/kg.
- The additive may pose risks as a skin and respiratory sensitiser.

## Abstract

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on Loigolactobacillus coryniformis DSM 34345 when used as a technological additive to improve ensiling of fresh plant material. The additive is intended for use with all fresh plant material for all animal species at a proposed minimum concentration of 1 × 108 colony forming units (CFU)/kg fresh plant material. The bacterial species L. coryniformis is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. The identity of the strain was established and no acquired antimicrobial resistance genes of concern were detected. Therefore, the FEEDAP Panel concluded that the use of the strain as a silage additive is considered safe for all the animal species, for consumers of products from animals fed the treated silage and for the environment. Regarding user safety, the additive containing Loigolactobacillus coryniformis DSM 34345 should be considered as a potential skin and respiratory sensitiser, and any exposure through skin and respiratory tract is considered a risk. One preparation was shown not to be irritant to skin or eyes. However, the Panel cannot assess the irritation potential of other possible preparations. The FEEDAP Panel concluded that Loigolactobacillus coryniformis DSM 34345 has the potential to improve the production of silages prepared from all fresh plant materials at a minimum concentration of 1 × 108 CFU/kg fresh material.
