The Northern Ireland protocol is proving a “monumental” challenge for officials implementing EU rules at the ports, the chief vet said.
On New Year’s Day, following the end of the Brexit transition, some traders arriving did not pre-notify about their goods, meaning that had to be done retrospectively.
The Government’s senior vet, Dr Robert Huey, said he expected traffic through the ports next week to be busier and added companies wanted to comply.
He said: “Pieces are coming together, it is just a matter of time and giving the industry time to adjust to this monumental challenge.”
The Northern Ireland protocol means animal products arriving from Great Britain must fulfil EU standards and paperwork requirements.
