Food sampling has been extended in Miyagi, Yamagata, Saitama, Chiba, Niigata and Nagano toinclude agricultural and livestock products.? Hong Kong, China has reported that they have tested 288 consignments of imported food fromJapan between 12 and 23 March. Three samples were found to exceed the Iodine-131 guidelineestablished by Codex.? The chief of Nuclear Safety Commission of Japan announced on 23 March that “fuel of reactor 1may be melted at certain amount and continues to be most critical condition compared withreactor 2 or 3”.? The Japan Medical Association started to ship insulin to affected sites but there has beendifficulty in reaching the affected areas because of bad road conditions and lack of petrol.? A physician from Niigata University conducted an investigation in a high risk population for deepvein thrombosis and pulmonary embolism and reported cases of embolism in the legs.? Fukushima Daiichi nuclear power plant:o Electricity supply has resumed at reactors 5 and 6. Reactor 3 already had light in thecontrol unit as of the evening of 22 March. The final check-up of electrical equipment isunderway at reactors 1, 2 and 4 before they will turn on the electricity.o Water spraying and injecting operations are ongoing at reactors 3 and 4. Temperatureof spent fuel storage pool for unit 4 was recorded 100C on 24 March.o Coolant pump did not work on 23 March for unit 5, a replacement will be done on 24March.o Higher than expected radiation levels continue to be detected at the plant facility mostrecently at the main gate; however, radiation levels are continuing to fall.o On 24 March, white smoke/steam was observed from the Nos. 1-4 reactor buildingaccording to media.? FAO-IAEA-WHO issued a Joint Statement on food safety issues following the Fukushima Daiichinuclear emergency.WHO SITREP NO 152EVENT INFORMATIONWeather(Source: Japan Meteorological Agency, 06:00, 23 March)23 and 24 March: Northern part of Tohoku (Pacific side) and Kanto area may have snow or rainin the afternoon.23-29 March: Minimum and maximum temperature will be lower than usual and it may dropbelow freezing in the morning and evening in Tohoku (Pacific side) and northern part of Kanto.POPULATION STATUSCombined deaths and missing counts are > 23 000.Table 1: Confirmed number of deaths, missing, injured and evacuated persons (24 March)Prefectures Death Missing Injured EvacueeHokkaido 1 3Aomori 3 1 66 367Iwate 2,939 4,947 130 44,271Miyagi 5,714 6,196 1030 100,835(Including evacuees from Fukushima)Akita 8Yamagata 1 20 3,595 (Evacuees from Fukushima and Miyagi)Fukushima 812 4,920 220 83,778Tokyo 7 77 740 (Evacuees from Fukushima and Miyagi)Ibaragi 20 1 662 3,137 (Including evacuees from Fukushima)Tochigi 4 133 2,951 (Including evacuees from Fukushima)Gunma 1 35 3,323(Evacuees from Fukushima and Miyagi)Saitama 42 3,396(Evacuees from Fukushima etc.)Chiba 17 2 194 1,413 (Including evacuees from Fukushima and Miyagi)Kanagawa 4 127 537 (Evacuees from Fukushima)Niigata 2 7,519 (Evacuees from Fukushima)Yamanashi 1 664(Evacuees from Fukushima and Miyagi)Shizuoka 4 243(Evacuees from Fukushima)Kouchi 1Nagano 294 (Evacuees from Fukushima)Total 9,523 16,067 2,755 257,063HEALTH STATUS, LIFELINE SERVICES AND RESPONSECommunicable diseasesNo further updates on cases of ILI and gastroenteristis.An internet-based ad-hoc surveillance system has been developed by Infectious DiseaseSurveillance Center, National Institute of Infectious Diseases (http://www.syndromicsurveillance.net/hinanjo/index.html), but is not functioning as of the morning of 23 March.3Non-communicable diseasesThe Japan Medical Association started to ship insulin to affected sites but there has beendifficulty in reaching the affected areas because of bad road conditions and lack of petrol.Care of the elderlyIt was reported that there were 15 out of 170 elderly who died within one week afterevacuation.Tsunami-related symptoms/aspiration pneumonia?

On 24 March, white smoke/steam was observed from the Nos. 1 - 4 reactor building accordingto media.5Radiation levelsHigher than expected radiation levels continue to be detected at the plant facility, mostrecently at the main gate, west of reactor 2; however, radiation levels are continuing to fall.Due to cooling and electric operations at the plant, radiation levels have not been consistentlymeasured at the main gate since 17 March. Key measurement values, locations and dates areas follows:7Table 5: Levels of radiation measured at nearby prefectures (24 March)Monitoring of seawater qualityTEPCO has reported contamination of seawater with radioactive iodine and cesium. The levelsreported were as follow:0.343 0.141 0.096 0.120 0.104 0.146COMMENTS: Yellow indicates higher than background level; all times in Tokyo time*for Saitama, last measure done at 14:00-15:00CONTACTS FOR MORE INFORMATIONWPRO Situation Room: GPN: 89250; SITROOM@wpro.who.int+ 63-2 528 9035+ 63-2 528 9650+ 63-2 528 9249+ 63-2 528 9341For further information: Mr Peter CordingleyPublic Information OfficerMobile: +63 918 963 0224Dr Art PesiganEmergency and Humanitarian ActionMobile: +63 918 917 8053
