We used to fish a lovely piece of river on a local farm (my pb Barbel at 15lb) but the farmer banned anyone using tinned luncheon meat in case it caused F&M.
Couple of other odd things:
The son of a friend was a trainee vet - they were conscripted and given an inordinate salary to do nothing more than put animals down during the F&M outbreak.
At the same time a local farmer was sending cattle from Surrey to Scotland and back through the outbreak so that the beef got a "Scottish reared" sticker. And they were only on Scottish soil for 2 days before going to one of the biggest supermarkets.
In the last outbreak another local farm had one half of land locked down and the other half of the farm, divided only by a narrow lane, fully open. I don't think anyone told all the deer we have around here!
