## TL;DR

This paper evaluates the effectiveness and safety of a probiotic additive for dogs, finding it potentially effective at a specific dosage but irritating to the eyes.

## Contribution

The study provides new evidence on the efficacy and safety profile of Bifidobacterium longum CNCM I-5642 for use in dog feed.

## Key findings

- The additive is irritant to the eyes but not to the skin.
- The additive may be effective at 1 × 109 CFU per dog per day.
- Safety for users remains a concern due to potential sensitisation.

## Abstract

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of Bifidobacterium longum CNCM I‐5642 (PP102I) as a zootechnical feed additive (functional group: physiological condition stabiliser) for dogs. In a previous opinion, the FEEDAP Panel concluded that PP102I was safe for dogs and the environment. Regarding the safety for the users, the Panel concluded that the additive should be considered a skin and respiratory sensitiser. Due to the lack of data, no conclusions could be drawn on the potential for skin/eye irritancy of the additive. Due to the lack of sufficient data, the Panel could not conclude on the efficacy of the additive for dogs at the proposed conditions of use. The applicant submitted in vitro eye and skin irritation tests and one efficacy trial in dogs to address the inconclusive aspects of the previous assessment. Based on the data provided, the Panel considers that the additive is irritant to the eyes but not to the skin. The additive has the potential to be efficacious when included in feed for dogs at 1 × 109 colony forming unit (CFU)/dog per day (which would correspond approximately to 3.5 × 109 CFU/kg complete feed).
