The Asda supplier's Cleckheaton factory was hit by fire in the early hours of 13 February. Firefighters saved the processing and slicing equipment.
Bernard Matthews has given the company factory space and staff assistance at its Great Witchingham headquarters in Norfolk. Specialist equipment is being installed and production is expected to start this week.
"The swift response of Bernard Matthews to our situation has meant that in just over a week since the factory fire, Forza will be fully operational," said Forza chief executive Max Hilliard. "The prompt action and support is greatly appreciated and has resulted in a smooth temporary re-location of our production facility and Forza staff to Norfolk."
