Previous studies have indicated that certain margarine samples may contain traces (∼ 1 ppb) of NMOR. The results of this present study indicated that packaging papers were the source of the contamination. Waxed wrappings and margarine samples taken from 1 cm outer layer of margarine blocks were found to contain NMOR, but those taken from the center of the margarine blocks were always negative. This suggests migration of NMOR from wrappings to the outer layers of the margarine blocks. Samples packaged in aluminum‐backed papers, specially coated waxed papers, or plastic containers were negative as determined by Thermal Energy Analyzer technique.
