After taking the pigs and speaking to the abattoir, we explained we were not sure and they crossed out the "non" bit so left it as Finisher - Controlled so the testing was not needed.
I agree I think it is a one fit all that is more relevant to other EU countries. It is just the website document gives some guidance but it is very generic and hard to interpret. It may be more of a risk in high production sites as well where biosecurity is potentially an issue.
I have made a note of this so the next time I take pigs, I don't have this headache. (Hopefully)
