Details	Cadmium (Cd) is one of the food contaminant, but the Food Hygiene Law doesn't show the standard value in oysters and wild meat of birds and beasts (givier). In order to evaluate the sanitary environment of Hiroshima area, we collected wild oysters (Crassostrea gigas), mud and commercially available givier for the measurements of zinc (Zn) and Cd concentration. The commercially available givier offered to the measurement was 2 samples of wild boar meat and 6 samples of venison. Cd was detected in 2 out of the 6 samples of venison (33.3%). The Cd concentration of the venison was lower than those of oyster meat and shell. We also performed an eating habit investigation for the inhabitants of Hiroshima area, the total number of whom was 381. A higher frequency was observed for the capture than the purchase to get givier of all kinds in total (p<0.01). However, the frequency of the capture was lower than the purchase for wild boar meat (p<0.05). On the other hand, the frequency of the capture was higher than that of purchase for venison (p<0.05). Inhabitants who think the givier-eating contributes to the economic promotion of local area around Hiroshima accounted for the majority in the generation of 30 to 40 years old. In addition, the answer, which doesn't contribute, occupied a fixed rate in all generations (24.6 ± 3.6 %). It is well known that Cd distribute with high concentration in kidney and liver but not in meat. Therefore, accumulation to Cd could be big in venison and not so low in wild boar. To investigate the Cd contamination in land and marine products and to inform them to public is necessary for the reduction of Cd intake of the consumer.
