Bread production at Warburtons Hereford Street bakery is due to restart in September, following a fire at the site on 29 July.
However, a spokesperson for the firm said that snack production at its ChippidyDooDaa plant was currently on hold, after 15-20% of the plant was damaged in the fire.
“The snack plant has been taken out and the team is assessing what will happen going forward,” she added.
Dispatch at Hereford Street is fully operational, with Warburtons’ 13 other bakeries ensuring that its bread deliveries have remained uninterrupted.
One hundred people had to be evacuated as 60 firefighters fought the blaze, which is thought to have started in an industrial oven in the snack plant.
