Those who buy blueberries from the supermarket should take every precaution to make certain that they wash them thoroughly before eating them. It will be important not to put them in a sink filled with water when washing them though, as the standing water can spread contaminants from one berry to the next.

The best and most efficient method of cleaning berries that you get from the store is to put them in a strainer and let water pour over them, so you can make sure to get off all the contaminants and chemicals that may have been sprayed on them.
