Hijiki seaweed (Sargassum fusiforme) is regarded as iron source in Japan, although that hijiki seaweed contains excessive amounts of inorganic arsenic. The PTWI of inorganic arsenic once established by the WHO had been withdrawn, because the JECFA concluded that the current PTWI for inorganic arsenic was no longer health protective. We have reported how many baby food products containing hijiki seaweed are on the market in Japan in the previously report. The 24 baby food items were found to contain hijiki seaweed in the 560 baby food products (4.3 %). In this study we aimed to measure amounts of hijiki seaweed in 10 baby food products. The highest hijiki content was 3.8 g/ individual package, and the smallest was 0.4 g/ individual package. The average hijiki content in 10 items was 1.5 g/ individual package, and the median was 0.9 g/ individual package. It is necessary to pay attention to use of hijiki seaweed for babies and toddlers.
