Not only is it fairly well encapsulated in plastic, the cadmium sulfide / cadmium selenide pigments are far less toxic when consumed orally than say the old lead carbonate pigment (known for being used as a white paint pigment) due to its poor solubility. https://en.wikipedia.org/wiki/Cadmium_pigments https://en.wikipedia.org/wiki/Cadmium_pigments If the kids are old enough not to put legos in their mouth and choke on them and can be encouraged to wash their hands before meals, I wouldn't worry too much, personally.
