Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of a preparation of dried cells of Saccharomyces cerevisiae CBS 493.94 (Yea‐Sacc®) as a zootechnical additive for dairy cows, minor dairy ruminant species, cattle for fattening and minor ruminant species for fattening. The feed additive is marketed in two solid forms (Yea‐Sacc® C and Yea‐Sacc® TS) differing by the granulometry. The applicant provided evidence that the additive currently in the market complies with the existing terms of the authorisation. The Panel concluded that the additive remains safe for the target species, consumers and the environment. Regarding the safety for the user, Yea‐Sacc® TS is non‐irritant to the skin or eyes while Yea‐Sacc® C is not irritant to the skin but irritant to the eyes. The additive in both formulations should be considered a skin and respiratory sensitiser and any exposure through skin and respiratory tract is considered a risk. There is no need to assess the efficacy of the additive in the context of the renewal of the authorisation.
