US Food and Drug Administration (FDA) tau lees paub ob peb xyoos tom qab ntawd tias nqaij qaib muag hauv Asmeskas muaj arsenic, tshuaj lom uas ua rau mob qog noj ntshav siab. Cov tshuaj lom no txhob txwm tshaj tawm ntxiv rau qaib noj. Yog li, dhau 60 xyoo dhau los, cov neeg Asmeskas uas noj nqaij qaib tau txais qee yam tshuaj lossis lwm yam tshuaj uas ua rau mob qog noj ntshav. Ua ntej txoj kev tshawb fawb no, kev lag luam nqaij qaib thiab FDA tsis kam lees tias arsenic muab rau qaib tau noj rau hauv lawv cov nqaij. Tau 60 xyoo, cov neeg hauv Tebchaws Meskas tau hais tias "arsenic raug tshem tawm ntawm lub cev nqaij qaib nrog excrement." Tsis muaj lub hauv paus kev tshawb fawb rau nqe lus no - kev lag luam nqaij qaib tsuas yog xav kom ntseeg. Tam sim no cov ntaub ntawv pov thawj tau meej heev, cov chaw tsim khoom noj nqaij qaib Roxarzon tau tshem cov khoom tawm ntawm lub txee. Curiously, Pfizer, cov chaw tsim khoom uas tau ntxiv arsenic rau nqaij qaib noj tag nrho, yog lub tuam txhab uas tsim cov tshuaj tiv thaiv nrog tshuaj ntxiv rau cov menyuam yaus. Scott Brown, ntawm Pfizer's Development thiab Veterinary Research Division, tau hais tias lub tuam txhab tau muag cov khoom xyaw tshuaj rau ntau lub tebchaws. Txawm li cas los xij, txawm tias qee lub tuam txhab txwv tsis pub muag qaib, FDA tseem hais ntxiv tias arsenic hauv nqaij qaib yog tsawg thiab muaj kev nyab xeeb rau noj. Kuj ceeb tias, thaum ua kom cov neeg siv khoom paub tseeb tias arsenic-infused nqaij qaib muaj kev nyab xeeb, FDA tshaj tawm qhov txaus ntshai ntawm kev haus cov kua txiv laus! Hauv kev tawm tsam tsis ntev los no, FDA tau liam tias cov neeg tsim cov kua txiv hmab txiv ntoo muag cov tshuaj tsis raug cai.
