Palm oil traders in the Madina market have voluntarily handed over gallons of palm oil to the Foods and Drugs Authority (FDA) to test if they are safe for human consumption.
Secretary of the Palm Oil Sellers Association at the Madina market Sandra Danso says they will continue to subject their product to the FDA for regular inspection.
"We don't know whether they have mixed it with Sudan dye that is why we are bringing all out.
"From next week they will bring the new ones and we will invite the Food and Drugs Authority to come and test if it still has sudan dye," she said.
Head of Food Safety Management at the FDA, Maria Aba Lovelace-Johnson told the media vendors whose products fail the test would face sanctions.
"When we find that they have a sudan dye we will really let the law apply to them.
"You know the law Act 851, the Public Health Act 2012 states categorically that if you adulterate food it is an offence.
"If you put into food any substance that is poisonous or injurious to health you have committed an offence," she explained.
The Food and Drugs Authority (FDA) has stepped up its surveillance on the sale of palm oils nation-wide, after it warned the public of the sale of palm oil adulterated with Sudan IV (Sudee) dye on the market.
The FDA on October 21, 2015 issued a press statement cautioning the public on the adulterated palm oil sold in 10 markets in the Greater Accra Region.
The markets are the Mallam, Mallam Atta, Dome, Dansoman, Agbogbloshie, Kaneshie, Tema Community 1, Ashiaman, Madina and Makola No 2.
