(Radio Iowa) – Federal drug agents are warning Iowa parents about so-called “rainbow fentanyl” being a potential danger to kids going trick-or-treating next month. Emily Murray, spokeswoman for the regional U-S Drug Enforcement Agency office in Omaha, says they haven’t seen any evidence of that controversial, colorful killer in the region — yet.

Halloween is a month away yet, but Murray urges Iowa parents to sort through all the candy their kids bring home before any of it is eaten.

Murray says there are some common sense steps to take, like not eating anything that’s not properly wrapped.

Along with the fentanyl dangers, Murray says the agency is still seeing — and seizing — large quantities of meth in the region.
