13,700 Blood Products Unusable at Red Cross After Freezer Power Failure; Lost Units Make up 1.2% of Annual Supply
Equipment malfunction was cited as the cause of the problem.
The Japanese Red Cross Society has since informed blood centers nationwide of the incident and urged them to implement stringent blood product management.
FFP, a blood product derived from donated blood and used for transfusions, plays a vital role in aiding blood coagulation, particularly in patients deficient in the coagulation factors necessary for blood clotting. It is unusual for such a large quantity of FFP to become unusable in a single incident.
According to the center, an alarm sounded at about 10:30 p.m. on May 11 following a power failure in the freezer at the center's Tatsumi supply substation, where blood products are stored. After the alert, a contractor was dispatched to respond to the issue. Repairs were completed and power was restored in about four hours.
A subsequent review of the temperature monitoring system revealed that the temperature had exceeded the standard freezing threshold of minus 20 C for 150 minutes, resulting in the loss of the units.
The center told The Yomiuri Shimbun that the issue stemmed from a terminal block with a different voltage standard being installed during an upgrade in May last year of the freezer's control panel, which regulates the temperature.
As a result, voltage exceeding a specified limit had been applied to the device's electrical circuit for a prolonged period of time, which could have damaged the control panel, it said.
According to one of the society's business reports, 2.15 million units of FFP were supplied to medical institutions in fiscal 2024, with each unit measuring 120 milliliters. The 13,700 units lost in this incident represent approximately 1.2% of the total annual supply.
While the center emphasized that alternative FFP could be supplied from national stockpiles with no impact on deliveries to medical institutions, it simultaneously announced plans to increase FFP production at its 11 manufacturing facilities nationwide.
The Japanese Red Cross did not report the incident to the Health, Labor and Welfare Ministry until June 10, a month after it happened and after being contacted by The Yomiuri Shimbun.

Hibakusha from Nagasaki picked for U.N. panel on nuke war effects
An atomic bomb survivor who is a doctor with experience treating other hibakusha and conducting leukemia research has been appointed to a new United Nations panel that examines the effects of nuclear war. 'Hiroshima and Nagasaki are real cities against which nuclear weapons were directly used, and Japanese researchers know the impact of nuclear weapons in totality,' said Masao Tomonaga, emeritus director of the Japanese Red Cross Nagasaki Atomic Bomb (Genbaku) Hospital. He is among the 21 members of the Scientific Panel on the Effects of Nuclear War announced by U.N. Secretary-General Antonio Guterres on July 17. The formation of the independent panel is 'a response to a global environment in which the risk of nuclear war is higher than at any point since the depths of the Cold War,' according to the United Nations. Tomonaga, 82, became a hematologist after graduating from Nagasaki University's School of Medicine. He expressed his eagerness to work on the international panel, saying there is a need to scientifically clarify what would occur in the event of a nuclear war. 'It is an honor to be selected as a researcher of atomic bombings,' the Nagasaki native said. 'I would like to speak about experiences in Nagasaki and Hiroshima, including developments over the (last) 80 years.' The panel was established in accordance with a U.N. General Assembly resolution adopted in December. It is tasked with examining 'the physical effects and societal consequences' of a nuclear war, and 'their impacts on public health, global socioeconomic systems, agriculture and ecosystems,' according to a U.N. statement. The panel is expected to hold its first meeting in September and submit its final report to the U.N. General Assembly session in 2027. (This article was written by Kyota Tanaka and Takashi Ogawa.)

Freezer glitch affects blood products at Red Cross center in Tokyo
A freezer glitch rendered about 13,700 units of fresh frozen plasma blood unusable at the Japanese Red Cross Society's blood center in Tokyo in May, it was learned Tuesday. The incident did not affect deliveries of blood products to medical institutions, and the affected units will be used as materials for other products that can be stored at higher temperatures, officials of the center said. On May 11, a freezer at the blood center in Tokyo's Koto Ward lost power around 10:30 p.m. Before the power was restored about four hours later, the temperature of the fresh frozen plasma blood units inside was above the standard level of minus 20 degrees Celsius for about two and a half hours. The power cut was caused by a faulty device installation in the temperature control panel, the officials said. The Japanese Red Cross Society reported the incident to the health ministry on June 10. At a news conference on Tuesday, health minister Takamaro Fukuoka said the ministry strongly demanded the society report any incident in a timely manner.
