In order to cope with risk issues of overseas on 4,4’-diaminodiphenylmethane (4,4’-MDA) known to used in the production of polyamide resins, we investigated on 4,4’-MDA migration from plastic cooking utensils. 93 samples of plastic cooking utensils were collected from the retail markets in 7 major cities of Korea during March to June, 2007 and 4,4’-MDA levels migrated to food simulants, water, 4% acetic acid, 20% ethanol and n-heptane, on plastic cooking utensils was quantified by liquid chromatography with tandem mass spectrometry (LC-MS/MS). 4,4’- MDA was detected in 14 samples, and the levels of 4,4’-MDA migrated to food simulants were in the range of 0.001 ~ 0.026 ppm. Among them, the 4,4’-MDA migration amounts of 2 samples were above 0.01 ppm defined by the EU.
