Welcome back, GA! Looks like the Scots had it right first time with the battered lettuce and cucumber — only safe way to eat the stuff with E-coli on the march. Yes, I know I'm wicked but the last (admittedly media-published so probably wrong) statistic I saw suggests a death rate of 0.73% (less than 1 in a 100). I don't know what the usual rate is for this kind of bacterial infection but this doesn't sound like a plague to me. And yes, I know it's terrible for the people affected and their relatives but, to put it bluntly, as is my wont, this is how life works. It annoys me that the media whip a frenzy of panic about every bloody thing! Look at the damage that has been done to Spanish farming. Most of my sympathy (but not all, obviously. Sorry to state the obvious, but it's so no-one gets hold of the wrong end of the stick — not to mention the fence-throwing antics we have seen elsewhere!) goes to them.
And no, we never will beat all the nasty bacteria because they evolve to cheat our traps — because that's how life on our dear beloved planet works.
