Apparently, when you purchase organic blueberries, you run the risk of getting a batch infected with maggots. These maggots, by all accounts, are harmless if accidentally consumed. However, just seeing them in your blueberry can be a traumatic experience.
When it comes to blueberries, a little bit of pesticide may actually go a long way. The female blueberry fruit fly lays her egg under the skin of the blueberry. The eggs hatch in the blueberry and the maggot/larva emerges. The maggot feeds on the pulp inside of the blueberry. The infested berries are packaged and sold to organic vendors. The vendors sell to consumers and the consumer, well, consumes the infested berries.
If you have never had an issue with blueberry maggots, then there is no need to give up your organic berries; instead, be aware that maggots in organic blueberries is a real possibility and stay alert while consuming your organic blueberries.
