Presentation Radiocesium and potassium decreases in wild edible plants by food processing

Tagami, Keiko  ,  Uchida, Shigeo

Radiocesium (134Cs+137Cs) concentrations in foods are of great concern since the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident as people want to avoid receiving additional internal dose from ingestion of the radionuclide. Food monitoring has been carried out; radioactivities of ca. 20-30 thousand samples are being measured and reported by the Ministry of Health, Labour and Welfare (MHLW). Most recent one year data showed that foods exceeding the standard limits were mostly from the wild, e.g. game animals, fish and wild mushrooms. One of the public’s main concerns is how to decrease ingestion of radiocesium from foods, especially foods they have collected from the wild as well as from their home-grown garden vegetables and fruits because radioactivities in these foods have not been measured for many cases. Thus, in the present study, we focused on food processing effects on radiocesium removal in food plants from the wild. Also radiocesium distributions in fruits (persimmon and loquat) are reported.
