Hi John,
In that case, it seems that you, Ken and whoever else took this at face value were pranked.
See https://www.snopes.com/fact-check/mad-cow-versus-brexit/
quoted from this website: If the graphic displayed above truly did show a map of Brexit voters on the left and a map of the 1990s' mad cow outbreak on the right, the correlation would be difficult to deny. However, the real reason that these two maps look so similar is that they are actually the same map, with one in color and one in grayscale. The creator of this image took a real map showing Brexit results, then altered the map's key, date, and color before sharing it on social media to satirize the results of the referendum.
I had assumed it was a prank, but looking closer at the 'BSE' map, the 'smile' across the south of England is suspicious. That (roughly) is the M4 Corridor; rural areas along one of the motorways to London, which have been urbanising (suburbanising?) over the last 40 (?) years. So, the sort of prosperous area which would have voted Remain; but 30 years previous probably had cattle, and so BSE.
(The high levels of BSE in Mid Wales, but not on the western Welsh coast, also struck me as odd)
