Cane rats and "shocking" quantities of illegal and "potentially unsafe" meat have been sold to the public in east London, BBC London has found.
Secret filming showed meat that broke food safety laws being prepared.
West African and environmental health officer sources said Ridley Road Market, in Dalston, was a known hotbed of illicit meat activity.
Traders have denied the claims while Hackney Council said it had only received one complaint since 2009.
BBC London's Guy Lynn spoke to chartered environmental health consultant Dr Yunes Teinaz, environmental health officer Paul Povey and African Health Policy Network chief Francis Kaikumba.
