Celebration and birthday cakes for the retail industry are made at the Hull site
Around 100 jobs at a cake and dessert-making company in the East Riding of Yorkshire are at risk after the firm announced it would be "restructuring".
Greencore, which makes cakes for the retail industry, said jobs at its Hull-based factory were being reviewed following the loss of a major contract.
The company said its site in Taunton, Somerset, would not be affected by the potential cuts.
Greencore said it would be working with unions throughout the process.
A company spokesman said "every effort" would be made to help affected employees find "alternative employment both inside and outside of the Greencore Group".
