Chlorpyrifos yakhala ikugwiritsidwa ntchito kwa zaka zopitilira 40 ndipo idalembetsedwa kuti igwiritsidwe ntchito m'maiko pafupifupi 100 pa mbewu zopitilira 50. Ngakhale chlorpyrifos idayambitsidwa kuti ilowe m'malo mwa mankhwala ophera tizilombo a organophosphorus, pali kafukufuku wochulukirachulukira kuti chlorpyrifos ikadali ndi mitundu ingapo yapoizoni yomwe ingakhalepo kwanthawi yayitali, makamaka kawopsedwe wodziwika bwino wa neurodevelopmental toxicity. Chifukwa cha zinthu zowopsa izi, Chlorpyrifos ndi chlorpyrifos-methyl akhala akuyenera kuletsedwa ndi European Union kuyambira 2020. Momwemonso, popeza chlorpyrifos kuwonetsa kungayambitse kuwonongeka kwa minyewa muubongo wa ana (yogwirizana ndi neurodevelopmental toxicity), California Environmental Protection Agency. adagwirizananso ndi wopanga kuti akhale ndi chiletso chokwanira pa kugulitsa ndi kugwiritsa ntchito chlorpyrifos kuyambira pa February 6, 2020.
