Consequently samples have been sent to the FDA laboratory in Accra for tesingt to ascertain whether they contain traces of the Sudan IV dye, a banned substance, Mr Matthew Gyan Nkum, Regional Director of the FDA told the Ghana News Agency in an interview.
He said samples from some educational institutions and corporate organizations like Newmont Gold Ghana Limited (NGGL), Ahafo Mine were earlier sent to Accra but they proved negative.
Mr Nkum said the samples from the Techiman market would be returned to their owners if the test also proves negative.
He stated that several test conducted in the Region had been negative but added however that the FDA was not relenting in its efforts to move out daily for screening because producers of palm oil have not stopped producing for the market.
Mr Nkum said the FDA is coming out with its policy of registering all palm oil sellers, so that they sell with tags and reference numbers traceable to their national identification cards.
