It's on your food and you don't know it
because growers are not mandated
to disclose poison
while organic growers have a higher standard.
It's curious that the US subsidies are available for these kinds of poisons to be used.
You can easily find this poison used on your corn, soybeans, nuts, Brussels sprouts, cranberries, broccoli, cauliflower and golf course turf among other things. The damage to humans is known and disregarded.
"Using Chlorpyrifos Products Safely
The current chlorpyrifos labels require workers handling and applying chlorpyrifos to wear additional personal protective equipment (chemical resistant gloves, coveralls, respirators), and restricting entry into treated fields for 24 hours up to five days.
Chlorpyrifos can cause cholinesterase inhibition in humans at high enough doses; that is, it can overstimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death."
