Scientific Opinion on the safety and efficacy of Biosprint® (Saccharomyces cerevisiae) as a feed additive for horses

EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)

Following a request from the European Commission, the European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the safety and efficacy of the product Biosprint® when used in feeds for horses at the minimum dose of 3.1 x 109 and a maximum of 6.0 x 109 CFU/kg of complete feedstuffs. The product is currently authorised for use in piglets, cattle for fattening, dairy cows and sows. Biosprint® consists of viable cells of Saccharomyces cerevisiae, which is considered by EFSA to be suitable for the QPS approach to safety assessment. As the identity of the active agent has been established, the use of Biosprint® can be presumed safe for horses, consumers and the environment. In the absence of data on skin and eye irritancy or skin sensitisation, Biosprint® should be considered as a potential irritant and sensitiser, and treated accordingly. Biosprint® S and Biosprint® G are unlikely to form respirable dust. Consequently, it is concluded that the inhalation exposure associated with the use of this product would be minimal. Three digestibility studies were provided in which Biosprint® used at the minimum recommended dose consistently increased apparent fibre digestion in adult horses.
