Legal notice: Relevant information or parts of this scientific output have been blackened in accordance with the confidentiality requests formulated by the applicant pending a decision thereon by the European Commission.

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of ProEquo® as a feed additive for horses. This additive is a preparation single strain of Lactobacillus plantarum intended for use as a zootechnical additive in feed for horses. The identity of the bacterial strain was not established. Consequently, the qualified presumption of safety approach to safety assessment cannot be applied, and separate studies on target animals, consumer and environmental safety are required. The tolerance trial provided could not be considered due to non‐compliance with the minimum requirements. No additional studies or data were provided for the other safety aspects. Therefore, in the absence of data, the FEEDAP Panel was not in the position to conclude on the safety of ProEquo® for the target animals, consumers of products derived from animals fed the additive and the environment. ProEquo® should be considered a respiratory sensitiser. In the absence of data, the FEEDAP Panel cannot conclude on the irritancy potential of the additive to skin and eyes or on its dermal sensitisation potential. The FEEDAP Panel is not in the position to conclude on the efficacy of ProEquo® for horses.
