Kev noj ntau ntawm aflatoxins ua rau mob hnyav (aflatoxicosis) uas tuaj yeem ua rau lub neej hem, feem ntau los ntawm kev puas tsuaj rau daim siab.
Aflatoxin B1 yog ib qho aflatoxin tsim los ntawm Aspergillus flavus thiab A. parasiticus.Nws yog ib tug muaj zog carcinogen.Qhov muaj peev xwm carcinogenic no txawv ntawm cov tsiaj nrog qee yam, xws li nas thiab liab, zoo li muaj kev cuam tshuam ntau dua li lwm tus.Aflatoxin B1 yog cov kab mob sib kis nyob rau hauv ntau yam khoom noj xws li txiv laum huab xeeb, zaub mov noj, pob kws, thiab lwm yam nplej;ib yam li tsiaj pub.Aflatoxin B1 yog suav tias yog cov tshuaj lom aflatoxin tshaj plaws thiab nws muaj feem cuam tshuam rau hauv hepatocellular carcinoma (HCC) hauv tib neeg.Ntau cov qauv thiab kev tshuaj ntsuam xyuas suav nrog nyias txheej chromatography (TLC), kev ua haujlwm siab ua kua chromatography (HPLC), pawg spectrometry, thiab enzyme-linked immunosorbent assay (ELISA), thiab lwm yam, tau siv los kuaj rau aflatoxin B1 paug hauv cov khoom noj. .Raws li Lub Koom Haum Saib Xyuas Khoom Noj thiab Kev Ua Liaj Ua Teb (FAO), thoob ntiaj teb kev zam siab tshaj plaws ntawm aflatoxin B1 tau tshaj tawm tias nyob rau hauv thaj tsam ntawm 1-20 μg / kg hauv cov zaub mov, thiab 5-50 μg / kg hauv cov nyuj noj zaub mov hauv xyoo 2003.
