Twenty years plus ago, there was a butcher shop somewhere near the small charity shop in Lordship Lane. My wife bought some beef mince and when she got it home found that some of it had FUR on it! She took it back and the butcher refused to do anything about it. I called the council who, really quickly, bought their own mince, had it analysed and found it was rabbit and beef mixture Butcher was prosecuted but I can't remember the outcome.
