Cadbury Schweppes has said that it will increase product testing at its Marlbrook factory at the centre of its recent salmonella scare.

Following a meeting yesterday with officials from the Food Standards Agency and Herefordshire Council, the FSA said that Cadbury would operate a positive release system, with products only being released for onward distribution after they tested negative for salmonella.

It would also conduct a comprehensive cleaning of its production lines and increase sampling and testing levels.

Earlier this week Cadbury's testing procedure was criticised by the Advisory Committee on the Microbiological Safety of Food for being old-fashioned and unreliable.
