This is how I read the Spanish Steak remark. In the late summer/Autumn of 2000 there was a scare that Spanish Cattle had become infected with mad cow disease. This was not the real reality of the situation, there had been one case reported, but that media coverage of that one case brought a standstill to the purchase of Spanish beef. This left a lot of beef and no customers, thus quickly it's price dropped and was bought by big restaurant chains, etc... I think this was followed by a news report which then in turn scared people into thinking they had eaten infected cattle and become infected with Mad Cows disease...but then I've possibly read a little too much between the lines on that comment.
I should point out I am a vegetarian and in no way have contracted 'mad cows' myself.
