Can the United Kingdom break brexit?

A few days after Brexit went into full effect at the beginning of 2021, Dutch TV news aired footage of customs officers confiscating ham sandwiches from a lorry driver arriving by ferry from the UK. Under post-Brexit rules, apparently, anyone coming from the UK is banned from personally importing meat and dairy products into the EU. Officials wearing high-visibility jackets were shown explaining to startled car and lorry drivers at the Hook of Holland ferry terminal that since Brexit, “you are no longer allowed to bring certain foods to Europe, like meat, fruit, vegetables, fish, that kind of stuff.”
