The UK government has issued new guidance for livestock exports and movements to the EU and Northern Ireland, effective from January 1, 2021. The guidance emphasizes the change in ear tag identification from 'UK' to 'GB' for animals exported to the EU, in compliance with the Northern Ireland Protocol. The government is urging livestock exporters to prepare for these changes by updating ear tags, confirming acceptance with importers, and ensuring compliance with the new EU Export Health Certificate requirements.
