That's because wild blueberries have a higher skin-to-pulp ratio which, according to the Wild Blueberry Association of North America (WBANA), gives the fruits more antioxidant-rich pigments, fiber, and intensity.

In far-flung fields and barrens, wild blueberries sit ripening in the sun, awaiting the rake each summer in Maine, the United States' largest producer of wild blueberries. Every year, beginning in late July and early August, crews head to the fields and barrens to carefully rake 'em up.

For that matter, wild blueberries growing next to a farm could potentially be exposed to pesticides used on other crops. Wild blueberries that are certified organic should be free of all but organic-approved pesticides. But either way, I don't think that pesticides on blueberries poses a concern for your health.

Cultivated blueberries are fairly uniform in their size, color and taste. Wild blueberries are generally much smaller in size than cultivated. They also vary in color from different shades of blue to almost black. Taste varies from very sweet to not-so-sweet.
