Abstract

In 1995, a cluster of six cases of hepatitis B infection was detected after transplantation of bone marrow or peripheral blood stem cells (Tedder et al., 1995). In four of these cases, infection appeared to have originated from a single infected
bone marrow sample stored in the same liquid nitrogen tank as non-infected samples (Hawkins et al., 1996). Hepatitis B viral DNA was found in detritus extracted from the storage tank. Contamination of the liquid nitrogen appeared to have occurred as a result of the infected material coming into contact
with the liquid nitrogen through unsealed parts of the cryopreservation bag.
