The people in Oslo woke up to the news today that there are parasites in our drinking water. All water should be set to boil for 3 minutes before use, before drinking it or preparing food and brushing teeth.
Usually Norwegians are very proud of the clean water we have here, but sometimes we hear differently. A while back there was a Giardia infection spreading in Bergen, where approx. 6000 people were ill. Some haven't recovered yet.
So far, noone in Oslo are ill due to the water, so hopefully the water isn't badly infected. Until further notice I'll boil all my water before use.
