# Safety and efficacy of a feed additive consisting of endo‐1,4‐beta‐xylanase produced with Bacillus subtilis LMG S‐15136 (Belfeed B MP/ML) (4a1606i) for all poultry species, suckling and weaned piglets, pigs for fattening, lactating sows and all minor porcine species other than reproductive animals for the renewal of its authorisation and the extension of its use to all Suidae (Puratos NV)

## TL;DR

This paper evaluates the safety and efficacy of a feed additive containing endo-1,4-beta-xylanase for various animal species, confirming its safety and effectiveness under approved conditions.

## Contribution

The study confirms the renewal of authorization and extension of use of the feed additive to all porcine species.

## Key findings

- The additive Belfeed B MP/ML is safe for target species, consumers, and the environment under approved conditions.
- The additive is efficacious in all porcine species at 10 IU endo-1,4-beta-xylanase/kg feed.
- High microbial contamination levels in Belfeed B MP require monitoring during production.

## Abstract

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of endo‐1,4‐beta‐xylanase (produced with Bacillus subtilis LMG S‐15136) (Belfeed B MP/ML) as a zootechnical additive (functional group: digestibility enhancers) in feed for all poultry species and Suidae. The additive is currently authorised for all poultry species, suckling and weaned piglets, pigs for fattening, lactating sows and all minor porcine species other than reproductive animals. This scientific opinion concerns the request for the renewal of the authorisation of the additive for these species and the extension of use to all porcine species/categories. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisations. The FEEDAP Panel concluded that the additive Belfeed B MP/ML remains safe for the target species, the consumer and the environment under the approved conditions of the authorisations. The extension of use to all porcine species would not affect these conclusions; therefore, the additive is considered safe for the target species, the consumer and the environment. Regarding the safety for the user, the two formulations of the additive are considered skin and eye irritants, and respiratory sensitisers. Any exposure of the user is considered a risk. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation. The FEEDAP Panel concluded that the additive is efficacious in all porcine species/categories at 10 IU endo‐1,4‐beta‐xylanase/kg complete feed. The Panel noted that the analytical values found for microbial contamination in Belfeed B MP are high and deserve attention/monitoring during the production process.
