Up to 60 firefighters tackled a blaze involving 450 tonnes of chocolate at a Cadbury factory in Herefordshire.
Crews were called to the Marlbrook plant near Leominster on Friday evening when a fire broke out in a 100ft tall silo containing liquid chocolate.
Although the blaze has been brought under control crews are still at the scene damping down.
An inquiry into the fire has been launched while the company is assessing damage to the production line.
No one was injured in the fire.
