(Decanter) - Fortnum & Mason has said graphic undercover footage filmed at foie gras farms in France does not come from its suppliers – and it has threatened legal action against animal rights group PETA. Animal rights group PETA (People for the Ethical Treatment of Animals) has released what it calls ‘shocking undercover video footage’ of farms it says are represented by the Sarlat Périgord cooperative, which supplies Fortnum & Mason foie gras distributor Georges Bruck.
