Heinz is set to sell its frozen ready meals manufacturing site in Dundalk, Ireland, to The Authentic Food Company for an undisclosed sum.

The factory, which employs 155 staff, was opened in 1993 and produces the WeightWatchers from Heinz, Ross and Heinz Big frozen ready meal ranges.

The proposed deal includes a three-year co-pack arrangement for The Authentic Food Company to continue to manufacture the products, with all Heinz staff expected to transfer to the Manchester-based world food specialist under the new ownership arrangements.

Heinz planned to continue working closely with The Authentic Food Company “to further develop the WeightWatchers from Heinz range, in addition to reviewing future opportunities for Heinz in frozen”, said the company in a statement.

The Authentic Food Company said it had plans for the continued expansion of its retail and foodservice business both in the UK and continental Europe “with the enhanced capability and capacity the site acquisition delivers”.
