More than a million Cadbury chocolate bars are to be removed from shelves amid fears that they may be contaminated with salmonella.

The contamination was caused by a leaking pipe at Cadbury's Marlbrook plant, near Leominster, Herefordshire.

"The levels are significantly below the standard that would be any health problem, but we are taking this measure as a precaution.
