WARNINGS have been re-issued about the dangers of using chilli powder containing an illegal dye.
West Yorkshire Trading Standards Service is warning retailers, caterers and consumers not to use or sell products containing the powder, which contains the red dye Sudan 1.
The dye is banned from food and is normally used in petrol, solvents and shoe polish.
If consumed regularly over a long period it can cause cancer.
Curry sauces and seasonings in the Rajah brand are affected.
The contaminated products are Rajah Tandoori Masala, Rajah Natural Tandoori Masala, Rajah Jerk Seasoning, Rajah Chilli and Lemon Seasoning, Rajah Oriental Noodle Seasoning, and Rajah Chicken Seasoning.
The products are sold in 100g, 400g, 1kg and 8kg packs.
Rajah has withdrawn affected products with a best before date prior to July 18, 2005.
However, checks by The Food Standards Agency at retailers and food outlets showed some were still using contaminated products, despite a food hazard warning issued on July 31.
Martin Wood, chief trading standards officer for West Yorkshire, said: "Anyone who has any of these products should throw them away."
The dye was found in chilli powder by scientists in France, in a consignment of ingredients heading for Shaws at Aspley, Huddersfield, which used it in its 1889 Yorkshire range, including chutney and relish. The firm was unaware the spices contained Sudan 1, as they were bought from a reputable importer.
