Hepatitis A virus (HAV) was detected in frozen strawberries which had been implicated in a large outbreak of hepatitis A in 1997. The sample was analysed after over 20 years of storage, following a standard method not available at the time of the outbreak. This is the first study in which the HAV associated with the 1997 outbreak of foodborne hepatitis has finally been detected.
