Food imports and Sudan dyes
All food imported to Northern Ireland from third countries must meet EU food safety standards. Controls are conducted on imported food to ensure such standards are being met, including sampling relevant commodities to ensure the absence of Sudan dyes. Any consignments found to contain Sudan dyes will be detained and prevented from entering the market.
Currently, enhanced import controls, under Regulation 2019/1793, exist upon Palm Oil from Ghana and Cote d'Ivoire. Imports from Ghana are listed on Annex II. Since 2003, all imports of dried, crushed and ground spices, curry powders, curcumin and palm oil have had to be accompanied by test certificates showing that they do not contain Sudan dyes. Any consignment without relevant documentation is detained and prevented from entering the market for sampling and analysis.
Border Control Post officers must also carry out random sampling. Any consignment found to contain industrial dye is destroyed.
Under current operating arrangements for Northern Ireland, food additives placed on the NI market will continue to follow EU rules. From Autumn 2023, the Windsor Framework will allow GB public health standards to apply for pre-packed retail goods moved via a new NI retail movement scheme and placed on the NI market. Therefore, goods moving via this route containing GB approved additives will be able to be placed on the NI market.
