Cadmium content in the product Upphandlingsmyndigheten

It is estimated that nearly 50% of all cadmium in plant foods comes from wheat flour and other cereal products. Cadmium is stored in or adjacent to the bran part and the germ in the wheat kernel and, therefore, whole grain or coarser flours contain higher levels of cadmium than finer wheat flour. All crops do not absorb cadmium in equal measures.
