Although blueberries can in fact be eaten raw, it is highly recommended that you wash them before eating them. There are certain pesticides which can stay on these berries even after they have been packaged and processed. By taking the time to prepare them for consumption, you will be able to avoid possible adverse health effects from pesticides and other things which are sprayed on the berries in order to reduce the risk of insects and other problems during the growing process.

Raw blueberries also don’t have the same kind of nutritional value as this which have been properly prepared, so you will want to consider that before simply eating them raw.
