There is no story in that article:
The updated 1,426-page Brexit deal between the UK and the EU says that each will have its own independent “sanitary” rules on products of animal origin, which means that products from either side must first pass specific checks before being allowed to be exported.
Post Brexit we can set our own rules, which may or may not conform with EU minimum standards. If we don’t comply with the standards then we have issues exporting, if we do conform with standards we don’t have issues exporting.
As a country that’s external to the EU our exporters need to produce more documentation.
Funny that an article with a deceptive title thanks the reader for reading the full article
