for once Wikipedia is not that far off.
The "it is likely that the infected meat had been illegally imported to the UK" is a bit like saying that it is likely that Hitler was responsible for WWII. Uk didn't have it, it comes on meat, don't legally import FMD meat, so either illegally imported or the tooth fairy brought it ! (except for 2007 when the Gov released it).
As per usual with Defra, both interpretation and consistency are to the fore, and the EU reg which bans the feeding of "catering waste" is interpreted by defra as ANY kitchen, and includes vegetarian restaurants for consistency and good measure !! The risk that your kitchen has any FMD infected meat is so close to zero as to be equivalent to David Cameron ringing you at 8.21 this evening to ask you to help out in Government. However rules is rules, as I would not advocate thatb you feed anything from your kitchen.
Finally, yes the rules do apply to pet pig keepers, in fact any pig keepers, as the risk is of transmission from live pig to live pig,sheep,cow,deer and thus to the to the UK herds of cattle and pigs and flocks of sheep, which can be via the air, rather than infected meat for eating (FMD is not harmful to humans).
