I have New Scientist No 2857, March 24, 2012 to thank, I guess, for bringing to my attention LFTB, that's lean finely textured beef. This matter, apparently delightfully and it would appear accurately called 'pink slime' is an additive to a range of meat products, and consists of 'slaughterhouse trimmings separated from fat and sterilised using ammonia'.
NS reports that the US Department of Agriculture has agreed to 'offer schools food without LFTB' post a 235,970 signature petition over March 2012.
What fascinates me about the story is that the petition was apparently based on 'microbiologists' concerns, and incidents of Escheria coli and Salmonella contamination - all of which were intercepted before reaching customers'. Why does this fascinate? Because I would have hoped that those 235,970 petitioners had petitioned for the removal of this muck from school canteens on the basis that it was repulsive crap to be feeding kids despite the manufacturer apparently claiming that LFTB is '94 to 97 per cent lean beef, with similar nutritional value to 90 per cent lean ground beef''.
I am all for eating offal not awful.
