I have frozen berries most mornings with either oatmeal or buckwheat pancakes, and often with ice cream. I prefer the mixture of raspberries, blackberries and blueberries. Amy doesn’t like the blackberries. Sorenne is a big fan of the blueberry. We also have fresh berries for a few months from my limited growing area and, more importantly, limited growing skill.

There have been multiple outbreaks of norovirus linked to frozen raspberries in several northern European countries, often linked to berries grown in southern European countries.

The journal Epidemiology and Infection has a great summary of 13 norovirus outbreaks in Finland in 2009 linked to frozen raspberries which sickened at least 900 people. Abstract below.

SUMMARY
In 2009, the number of foodborne norovirus outbreaks in Finland seemed markedly high, and many outbreaks seemed to be linked to imported frozen raspberries. We reviewed the data regarding all notified foodborne outbreaks in 2009 in Finland in order to assess the magnitude of the problem and to summarize the information on raspberry–linked outbreaks. Between March and August, 13 norovirus outbreaks affecting about 900 people could be linked to imported frozen raspberries. Two raspberry samples corresponding to two batches of raspberries were positive for norovirus. These two batches proved to have been the likely source in six of the 13 outbreaks. Analytical studies had not been conducted for six outbreaks, and virological test results were inconclusive in two. However, combining epidemiological and microbiological methods often enabled finding the source, as exemplified in investigation of a large school outbreak. To ensure prompt control measures in similar situations in the future, both aspects of outbreak investigations should be strengthened.
