Food safety expert Hugh Pennington answers your questions

BSE, or mad cow disease, is back in the headlines. The latest scare involving the disease comes from research that suggests that it could enter the human food chain by infecting pigs, sheep and poultry.

British scientists discovered that BSE could infect different species without them showing any sign of them carrying the illness. Up to now it had been thought that the species barrier made it difficult for BSE to pass to different species of animals.

Experts are divided over the significance of the findings. As one of the UK's leading experts, Professor Hugh Pennington of Aberdeen University has spoken out on a range of food safety issues including the BSE crisis.

Professor Pennington answered a selection of your questions in a live webcast. Select the link below to listen to his answers.
