The Food and Drug Administration (FDA) officials on Thursday said that at least 27 per cent of the 56 samples of cooking oil and other food items collected from four companies in Maharashtra`s Thane district have been found adulterated or with false claims.

The samples tested revealed that palmolein oil was mixed in products sold as sunflower and soyabean oils, rice bran oil was mixed in a product sold as mustard oil and vegetable oil was mixed in products claimed to be milk cream and ghee, FDA`s (Foods) Joint Commissioner, S R Kekre, told PTI.
