Fire crews returned to the scene of a major Norwich blaze this morning (Friday) after more smoke was spotted coming from the building.
The Broadland Hams factory on the Sweet Briar Industrial Estate was destroyed on Wednesday.
A fire service spokesman said something at the site was continuing to smoulder forcing crews to return this morning.
He said: 'We were called back to the building just before 8am after someone reported seeing some smoke. That's not unusual with a fire like this.'
Three crews and an aerial ladder attended and all had left the site by 12 noon after damping down and cutting away some panelling.
Fire fighters were originally called to the factory on Wednesday at about 1.30pm after workers returning from lunch raised the alarm.
The first engines arrived at 1.50pm but the fierce flames and thick smoke quickly spread, making it difficult for crews to tackle.
Eight appliances attended and after bringing it under control the firefighters supervised a controlled burn out.
Broadland Hams has been run by the Porter family since 1986. This week they vowed to get it up and running as soon as possible.
