Recalls/market withdrawals of blood components occur when blood centers act on additional information or discover manufacturing deviations after the time of component issue. Unfortunately, recalls occur fairly commonly; major recalls may impact blood availability, and even minor recalls cause distress in the hospital blood bank, as components have often already been transfused. Recall regulations and policies differ between countries and organizations, and international comparisons may assist in the development of best practices. Case examples of recalls will be presented, and the recall strategies used by different blood centers will be discussed.
