Contents and migration levels of lead and cadmium were measured by atomic absorption spectrophotometry and inductively coupled plasma spectrophotometry in various ornaments (cake-making decorations). Sticks which come in contact with food had no lead or cadmium. 112 decoration balls, consisting of coated plastic or wood, were tested. 45 balls contained lead and 8 balls contained cadmium over 1μg/g. Lead levels of 26 balls exceeded the limit of 100μg/g in the Food Sanitation Law. No lead and cadmium were eluted from decorations into heptane, so there is not much possibility that lead and cadmium in cake decorations will contaminate the cream on cakes. However, over 0.1μg/mL of lead migrated from 25 decoration balls in 4% acetic acid, and 3 decoration balls in water at 40℃. Contact with ornamental fruits, and human consumption, are therefore undesirable,
