A further 12 products contaminated with the illegal dye Para Red have been withdrawn from sale by the Food Standards Agency.

The recalled items include products by Castle MacLellan, Makro, Meridian, Somerfield and Weight Watchers.

The products add to the 35 items withdrawn by the FSA last week.

Para Red is a potentially cancer-causing industrial dye similar to Sudan 1 and was discovered to have contaminated food from General Mills’ Old El Paso range last month.
