When you see a plane overhead spraying for mosquitoes that carry the West Nile Virus, should you worry more about the virus or the chemicals in the spray?
The Sacramento-Yolo Mosquito and Vector Control uses spraying to keep the mosquito population down in areas where the West Nile Virus is detected, but that practice is once again drawing criticism over possible health risks.
A UC Davis report on pesticide use suggests long-term exposure could be harmful to children and pregnant women.
This is the same study we told you about which drew a link between pregnant women living near agricultural areas where pesticides are used and a higher risk of autism.
However, even the California EPA seems to dispute the study's findings, saying the chemicals used in the Sacramento area pose no risk to humans despite being considered carcinogenic in some cases.
