The European Union assesses the safety and efficacy of Saccharomyces cerevisiae CNCM I-1079 as a feed additive for animals such as calves

On October 25, 2022, according to the European Food Safety Authority (EFSA), at the request of the European Commission, The European Union Animal Feed Additives and Products (FEEDAP) Study Group gives a scientific opinion on the safety and efficacy of Saccharomyces cerevisae CNCM I-1079 as a feed additive for calves, all other ruminants, and camels for feeding and finishing.

Following this assessment, the expert panel concluded that the additive is safe for the target species, consumers and the environment. This additive is not a skin or eye irritant or a skin sensitizer, but it should be considered a respiratory sensitizer. In addition, the team could not draw conclusions about the efficacy of the additive on the target species. Some of the original reports are as follows:

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 Saccharomyces cerevisiae CNCM I-1079 when used as a zootechnical additive (gut flora stabilisers and physiological condition stabilisers) for calves, all other ruminant species and for camelids for rearing and for fattening. The product, manufactured in two forms, as a powder and an encapsulated form, is intended for use in complete feed at a minimum inclusion level of 1 × 109 CFU/kg complete feed. S. cerevisiae is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. Since the identity of the strain has been clearly established and the additive is composed mainly by dried cells of the active agent, the use of the additive in animal nutrition is considered safe for the target species, the consumer and the environment. The additive is not a skin or eye irritant, or a skin sensitiser, but should be considered a respiratory sensitiser. However, exposure by inhalation to the encapsulated form is unlikely. The Panel was not in the position to conclude on the efficacy of the additive for the target species.
