Around one in ten people in the south west who took part in a survey on food were tricked into saying they'd eaten things that don't really exist.
The questioners asked people if they'd tried a variety of foods including the made-up items chicken trotters and pigs wings.
Ten per cent of respondents apparently thought chickens had trotters and seven per cent that pigs could fly, because they said they'd eaten those parts of the animals.
The survey was conducted by the RSPCA's Freedom Foods labelling scheme as part of a campaign for better understanding about where food comes from.
