Pink slime is the American name given to what our food industry used to call MRM (mechanically reclaimed meat)...

The process involves sticking bovine off-cuts in a heated centrifuge, so they separate into a mixture of liquid fat and a putty-coloured paste. That substance is then treated with ammonium hydroxide (a chemical used in household cleaners and home-made bombs) to kill off salmonella and e-coli. Then it's mixed with regular beef and – hey presto! – you have "all natural" mince.
In January, McDonalds announced the removal of "pink slime" from its burgers.
Enjoy your meal...
