I’m still pissed I can’t figure out where my frozen berries are coming from.

Sure, I live in a sub-tropical climate with an abundance of berries, but retailers with the frozen berries will go for the cheapest source.

And frozen berries have been a mainstay of my diet for decades (because in Canada, fresh berries are available for about six weeks a year).

Guzman-Herrador et al. report in Eurosurveillance that on 7 March 2014, an increase in hepatitis A virus (HAV) infections was identified in Norway. As of 12 April, 19 cases of HAV infection with a virus strain identical to an ongoing European outbreak have been identified. Six probable cases are currently under investigation. On 11 April, a frozen berry mix cake imported from another European country was found as the likely source of the outbreak; the importer has withdrawn the product in Norway.

An international traceback investigation is ongoing to find the origin of the berries used in the cake.

Internationally, there’s been over 11,000 cases of Hepatitis A linked to berries from the Mediterranean region over the past two years.
