Blueberries
Below are the pesticides with established tolerances (residue limits for pesticides used in the U.S. or by countries exporting to the U.S.) for blueberries. While not all the pesticides on the list are applied to all blueberries, there is no way to tell which pesticides are applied to any given piece of conventional produce on your store shelf. You may consider talking to the farmers at your local farmers market about the pesticides they use, but eating organic is the only way to know for sure.
California Farmworker Poisonings, 1992-2007: Not a major California crop.
Pesticide Tolerances - Health and environmental effects: There are 40 pesticides with established tolerance for blueberries, 20 are acutely toxic creating a hazardous environment for farmworkers, 38 are linked to chronic health problems (such as cancer), 7 contaminate streams or groundwater, and 35 are poisonous to wildlife.
(A = acute health effects, C = chronic health effects, SW = surface water contaminant, GW = ground water contaminant, W = wildlife or bee poison, LT = long-range transport)
