To Fight Zika, Government Spraying Neurotoxin Known to Cause "Severe Reduction in Brain Weight" in Fetuses. What's worse: Zika or pesticide?

As more states are beginning to deploy aerial spraying campaigns to kill off mosquitoes, some scientists are warning the chemical spray could be harmful to humans in the long term. According to the Globe And Mail, "Of more than 12,000 pregnant Colombian women with Zika, only 21 have had fetuses or babies with the brain defects." Airplanes have already been flying over Miami spraying an EPA-approved insecticide called Naled. It's a neurotoxin that kills adult mosquitoes. But some scientists say high exposure to the chemicals used in Naled can have negative long-term health effects for humans. Animal testing found high exposure to trichlorfon, one of the main ingredients in Naled, could cause cancer and birth defects. Scientists at the University of Oslo tested trichlorfon on guinea pigs. They found that injections of the chemical in pregnant guinea pigs impacted the brain development of the fetuses. "When the offspring were examined at birth, there was a severe reduction in brain weight in the case of trichlorfon and dichlorvos, but not after treatment with the other organophosphates," the study says.
