Italy is also currently experiencing an outbreak of Hepatitis A infection involving genotype 1A. At the start of year the Italian outbreak appeared to be restricted to the autonomous provinces of Trento and Bolzano in northern Italy, however, it is now recognized to be a nationwide outbreak. The Italian authorities have detected the Hepatitis A virus in four frozen mixed berries products. The types of berries involved were raspberries, redcurrants, blackberries and blueberries. The frozen berry mix originated from Italy, with raw berry material sourced from various countries.
As of the 5th July 2013 a total of 59 confirmed cases and 103 probable cases of Hepatitis A infection were identified in Denmark, Sweden, Norway and Finland. The cases of infection in these countries were caused by Hepatitis A genotype 1B. Frozen strawberries sourced in Egypt and Morocco are the most likely source of food causing the outbreak.
The United States Centers for Disease Control and Prevention (CDC) reports that 150 people across eight States have been confirmed ill from Hepatitis A genotype 1B. Illness has been linked to eating a frozen berry and pomegranate seed mix. Data from their epidemiological investigation suggests the most likely source of the Hepatitis A virus appears to be a common shipment of pomegranate seeds from a company in Turkey. The outbreak strain, genotype 1B is rarely seen in the United States but circulates in the North Africa and Middle East regions. A 2012 Hepatitis A outbreak of genotype 1B in British Columbia is related to a frozen berry blend with pomegranate seeds from Egypt.
