During and after the Fukushima accident, the IRSN collected and interpreted the resultsof radiological measurements performed on foodstuffs of terrestrial origin published byJapan's Ministry of Health between mid-March 2011 and July 2012. Analysis of the findingsshows that the accident's date, livestock-rearing practices and the deposits'characteristics had a decisive influence. The fact that radioactive fallout occurred veryearly in the growing and breeding season largely explains the moderate contamination ofmost foodstuffs of terrestrial origin, notably in the areas with the largest deposits. Inthe case of dairy products and meat, feeding imported fodder to livestock in stables, acommon practice in Japan, compounded the calendar effect. Measurements published in Japanhave also borne out the particular sensitivity of mushrooms, including cultivated species,and game.
