If it's an area you have experience in, I know I would be really interested in your opinion on the food-related stuff in the document, as I'm sure other regular visitors to this thread would be.
In a nutshell all EU MSs and some others in EEA agree to comply with the Food and Feed Hygiene Regs - known as the Hygiene Package.
Every food or feed business operator is subject to regular inspections by the competent authority in each country. There is a permanent veterinary presence at all slaughtering plants during slaughter.
Once an FBO is approved it is given an approval number which it applies to all produce in an oval mark (or oval carcase stamp). The mark contains EC the number and the country letter code UK in your case. IE for Ireland, DE Germany etc.
If an FBO is found non-compliant there are consequences from minor right up to possible loss of approval.
All countries that operate these Regs can also expect regular EU audits which include inspections of approved premises.
The system is very strict and as a result there are relatively few food or feed incidents given the massive amount of production across the EU/EEA. When there is an incident it usually gets a lot of publicity with subsequent reputational damage to the FBO and possibly to the country of origin.
UK appears to be continuing with an oval mark and UK approval system. It remains to be seen if they continue to apply the same level of rigour to their regulation of FBOs and what level of independent audit will be applied in order to give assurances to consumers at home and abroad.
My sense is that the new UK oval mark without the EU regulatory assurances may have difficulties when it arrives on European shelves beside EU approved product.
That is before consideration of possible price differential due to tariffs.
Next time you buy meat check packaging for oval mark or, if fresh from a counter, the supplier should have clearly on display the details of the approved FBO that probided the fresh meat being sold.
These regs are in my view a very worthwhile and necessary bureaucratic evil to safeguard human health.
There are also reams of EU animal welfare regs that are important.
