Farmworkers get sick after Trump’s EPA reverses Obama and approves poison that damages kids’...

This pesticide was never banned and has been proven safe if properly applied. There has been no deaths attributed to this chemical in the USA. There was less than ten people kills with improper over exposure outside the USA many years ago. Very few cases of any long term health affects when correctly used.

All pesticides, herbicides, and chemical fertilizers are poisons; every single one. That is why almost every pesticide, herbicide, and chemical fertilizer used by commercial farmers requires a licensed, certified, person to apply it. Whether or not they are poisons; Whether or not they are dangerous, has never been in question. The only questions are can the risks be mitigated, and if so, do the benefits outweigh the risks.

Chlorpyrifos was never banned under the Obama administration. After periodic review, a report was filed recommending a ban. But under the Trump administration, the EPA has taken actions to help protect wildlife from chlorpyrifos exposure. For example, many of the reported incidents of wildlife mortality associated with chlorpyrifos use were related to unlicensed, uncertified applicators in residential lawn and termite uses and use on golf courses. The residential uses have been eliminated; termiticide uses have been restricted; and the application rate on golf courses has been reduced. Additionally, no-spray buffers around surface water bodies, as well as rate reductions for agricultural uses, further reduced the environmental burden of chlorpyrifos. - Source "Revised Human Health Risk Assessment on Chlorpyrifos" EPA.gov

But here is the rub, at commercially effective concentrations, all organic pesticides, herbicides, and fertilizers are also toxic and or unsafe. For example, Citronella is a highly effective pesticide. Citronella yes the stuff you but for picnic table candles) But in safe concentrations, Citronella is ineffective, and has virtually no commercially viable persistence. And almost all cases of commercial cases E. Coli can be traced to unsafe handling of organic fertilizers.

Except it was not actually banned. The EPA issued a proposal to DOW chemical in 2015 to revoke licenses for chlorpyrifos. That reopened the case. And as of November 2016 there was no ban of chlorpyrifos in the Obama administration EPA. Junk reporting to blame problems on politicians just because you don't like someone.

"According to Mother Jones, the Obama administration had taken steps to effectively ban the use of chlorpyrifos, but that changed after Trump appointed Scott Pruitt to lead the EPA."

1) Mother Jones. Enough said...
2) An "Effectively banned" chemical is not the same as banned.
