This corrigendum corrects an error in Commission Implementing Regulation (EU) 2026/154 of 23 January 2026 concerning the authorisation of sepiolitic clay as a feed additive for all animal species other than ruminants for milk production or reproduction, weaned piglets of porcine species, porcine species for fattening, salmonids and chickens for fattening and amending Implementing Regulation (EU) 2023/263 as regards the terms of the authorisation of sepiolitic clay as a feed additive for salmonids and chickens for fattening (Text with EEA relevance), notified on 5 February 2026. Implementing Regulation (EU) 2026/154 erroneously omitted to provide for the usual transitional measures, as regards all animal species other than ruminants for milk production or reproduction, weaned piglets of porcine species, porcine species for fattening, salmonids and chickens for fattening, allowing interested parties to prepare themselves to meet the new requirements resulting from the authorisation. Implementing Regulation (EU) 2026/154 is therefore corrected accordingly by this Act, which applies retroactively from the date of entry into force of Implementing Regulation (EU) 2026/154 (15 February 2026).
