Manufacturers are facing a bill for millions of pounds after a food scare which has led to the recall of more than 200 retail and foodservice lines.

Products caught up in the scare have included Unilever’s Bertolli Pesto Rosso, some Nando’s products and top selling own label ranges from Sainsbury, Safeway and Asda.

The scare, reported to be the longest running packaged food scare in UK retail history, centres on sauces made using chilli powder thought to contain the banned food dye Sudan 1.
