Concerns about pesticides can make the ''eat more fruit'' recommendation hard to swallow. I learned this from a reader who stopped eating blueberries when told they were high in pesticides. Here are the facts. In 2003 the Environmental Working Group tested and ranked 46 common fruits and vegetables for pesticide contamination. According to their findings, the produce with the highest amount of contamination, coined the dirty dozen, are peaches, strawberries, apples, spinach, nectarines, celery, pears, cherries, potatoes, bell peppers, raspberries and imported grapes. These would be the best choices for organic. Blueberries ranked No. 31.

I grow about 40 highbush blueberry plants and see few pests beyond birds .
