A couple of days ago, reports of illness associated with eating products containing frozen raspberries resulted in a number of recalls around Quebec. People who purchased these products, mostly frozen desserts, whole frozen berries, or pastries, have been asked to discard them or return them to where they were purchased. You can see a list of products and retail locations here.
It is important to note that norovirus can withstand freezing, and norovirus outbreaks involving frozen berries have happened on occasion. One exceptionally large and notable case happened in 2012, when over 11,000 people, mostly schoolchildren, became sick after eating desserts served in school cafeterias made from one large lot of frozen strawberries.
This story in Canada is a little new and it unclear whether norovirus has been confirmed to be the cause yet, or how many people have been sick. In looking at recent Canadian Food Inspection Agency recalls, one was put out on June 23rd for whole raspberries due to norovirus, but this has not been mentioned as linked to this event yet.
We will update this post if more information becomes available.
