I-US Food and Drug Administration (FDA) yabona eminyakeni embalwa kamuva ukuthi inyama yenkukhu ethengiswa e-US yayiqukethe i-arsenic, into enobuthi ebangela umdlavuza ngemithamo ephezulu. Leli khemikhali elinobuthi lifakwa ngamabomu ekudleni kwezinkukhu. Ngakho, phakathi neminyaka engu-60 edlule, abantu baseMelika abadla inkukhu baye bathola isilinganiso esithile noma elinye lamakhemikhali abangela umdlavuza. Ngaphambi kwalolu cwaningo, imboni yezinkukhu kanye ne-FDA bakuphikile ukuthi i-arsenic enikezwa izinkukhu yayingene enyameni yazo. Sekuyiminyaka engu-60 abantu base-United States betshelwa ukuthi “i-arsenic ikhishwa ngendle emzimbeni wenkukhu.” Kwakungekho sisekelo sesayensi salesi sitatimende - imboni yenkukhu yayifuna nje ukukholelwa. Manje njengoba ubufakazi sebucace kangaka, umenzi wokuphakelwa kwezinkukhu u-Roxarzon usewukhiphile umkhiqizo emashalofini. Kuyamangaza ukuthi i-Pfizer, umkhiqizi obelokhu enezela i-arsenic ekudleni kwezinkukhu, inkampani eyenza imithi yokugoma enezithako zamakhemikhali zezingane. UScott Brown, wePfizer's Development and Veterinary Research Division, uthe inkampani isidayisele inqwaba yamanye amazwe la makhemikhali. Kodwa-ke, naphezu kokuba abanye abakhiqizi beyeka ukuthengiswa kwezinkukhu, i-FDA iyaqhubeka nokusho ukuthi i-arsenic enyameni yenkukhu iphansi futhi iphephile ukudliwa. Ngokumangalisayo, ngenkathi iqinisekisa abathengi ukuthi inkukhu efakwe i-arsenic iphephile, i-FDA imemezela ubungozi bokudla ijusi ye-elderberry! Ekugaseleni kwakamuva, i-FDA isole abakhiqizi bejusi ngokuthengisa izidakamizwa ezingagunyaziwe.
