Commercial baby food was roughly classified into six food groups, including vegetable, fruit, fish, meat, dairy product, and cookie. Dioxin levels in commercial baby food were determined, and dioxin intake in infants was assessed on the basis of the proposed original model food groups. The total daily dioxin intake was 0.070 pg TEQ/kg body weight/day. The total dioxin intake in this study was considerably lower than the Tolerable daily intake (TDI) of 4 pg TEQ/kg body weight/day set by Japanese regulations. The dioxin intake from commercial baby food is considered not to be a serious problem at the moment. We believe that the proposed classification and calculation is suitable for the evaluation of total dioxin intake from commercial baby food.
