LONDON, Feb. 21 (Xinhuanet) -- British food quality watchdog added 38 more items to a list of food products contaminated with the illegal dye Sudan 1 on Monday.

    The Food Standards Agency said the additional products include sausages, seasonings, ready meals and pizzas from companies such as supermarket chains Morrisons, Sainsbury's and Waitrose.

    The agency published an original list of 357 products contaminated with the potentially cancer-causing dye on Friday. The dye was supplied from India to Premier Foods which manufactured a sauce used as a flavoring in the products.

    On Friday, the company said the problem was uncovered when supplies reached an Italian company which tested for Sudan 1.

    Jon Bell, an FSA spokesman, said the agency was liaising with manufacturers, retailers and local inspection teams to ensure contaminated products were removed from sale as soon as possible.

    "We are making it quite clear to all concerned that we expect them to have withdrawn all the products from the shelves by Thursday at the latest," he said.

    He added that "it was not sensible for people to be continuing to eat these products" although there was no immediate risk to health and overall rise was small.

    Customers who find any of the soups, sauces and ready-made meals in their cupboards to return the packaging to their retailer for a refund.

    The newly announced products took the number of contaminated food items to 395 and a full list of the products is available on the FSA website www.food.gov.uk. Enditem
