The Ham Sandwich Wars?

It sems to have come to a surprise to UK transport (for some reason, now termed 'logistics') companies that, from 11pm on December 31st, 2020, their drivers will not be allowed to take ham (with or without cheese) sandwiches into the EU (https://www.theguardian.com/politics/2020/dec/18/lorry-drivers-heading-to-eu-face-ham-sandwich-ban). Many of the drivers carry their home comforts in their cabs (they have refrigerators and microwaves). They will not be able, however, to carry meat or dairy products into the EU for biosecurity reasons. Meat and dairy products (whether home produced or shop bought) have been linked to serious animal infections,such as foot and mouth disease. Although their sandwiches are deemed safe until the 30th December 2020, post-Brexit, UK food materials have to be treated like that from any other 3rd country. In fairness, the sources of the ham and cheese used to make sandwiches by UK drivers could change from January 1st, 2021. Some companies are predicting 'fisticuffs', if their driver's lunch boxes are raided, but this is just one more consequence of leaving the EU.
