Muab lo rau  Kaum ib hlis 8, 2019, Kho los ntawm Samantha, Qeb  

Nyob rau hauv xyoo tas los no, mis nyuj hmoov kev nyab xeeb kev sib tsoo hauv khw mis nyuj tshwm sim ntau zaus. Cov mis hmoov melamine qhov xwm txheej ntawm Sanlu Group xav tsis thoob rau Tuam Tshoj xyoo 2008. Los ntawm qhov no, Suav tau kawm paub txog lawv tus kheej nrog cov lus tsis txaus ntseeg no thiab ntshai los tham txog nws. Tsis ntev tom qab qhov kev huam yuaj, peb cov neeg Suav tau rov qab nyiam dua los ntawm kev nyab xeeb ntawm mis hmoov thiab mis nyuj as -ham, ces kawm ib lo lus tshiab, aflatoxin.

Aflatoxin yog ib yam tshuaj lom heev. Aflatoxin muaj kev puas tsuaj rau tib neeg thiab tsiaj lub siab cov ntaub so ntswg thiab tuaj yeem ua rau mob qog noj ntshav lossis tuag taus thaum mob hnyav.

Cov aflatoxin hauv cov mis nyuj yog ib hom aflatoxin, M1 feem ntau muaj nyob rau hauv cov khoom siv mis nyuj. Nws yog hloov los ntawm aflatoxin B1 hauv nyuj pub. Tuam Tshoj muaj cov ntsiab lus siab tshaj plaws ntawm 0.5 g / kg (aflatoxin M1) rau cov mis nyuj thiab nws cov khoom (cov mis tsis muaj menyuam, cov mis nyuj tshiab, tag nrho cov mis hmoov, evaporated mis nyuj, qab zib condensed mis nyuj qab zib) thiab nqaij npuas tshiab (siab, raum, ntshav, thiab nqaij ntshiv).

Yuav ua li cas aflatoxin ua rau mob qog noj ntshav?
Cov kws tshaj lij taw qhia tias aflatoxin yog metabolized hauv daim siab tom qab tau nqus los ntawm tib neeg lub cev, tab sis cov tshuaj lom ntawm aflatoxin tuaj yeem tua ntau heev. hepatocytes thiab ua rau lub siab puas tsuaj, uas yuav loj hlob mus rau hauv cirrhosis ntawm daim siab thiab ces mob qog noj ntshav.

Aflatoxin induces hepatocellular carcinoma nyob rau hauv cov theem hauv qab no:
1. Dej zoo li degeneration ntawm hepatocytes.
2. Proliferative basophils tshwm sim, uas tuaj yeem nyob ib leeg lossis sib koom ua ke nrog dej zoo li degeneration.
3. Nodule regeneration nrog parenchymal hlwb.
4. Muaj cov hlwb hloov.
5. Tsim cov kab mob hepatocellular carcinoma.

Cov kab lus no feem ntau txheeb xyuas cov xwm txheej ntawm aflatoxin tshaj li tus qauv hauv cov mis nyuj ntawm lub tuam txhab nyuj hauv xyoo tas los. Raws li kev tshaj tawm ntawm General Administration of Quality Supervision and Inspection nyob rau hauv 2011, ib pawg ntawm cov khoom tsim los ntawm Mengniu Dairy (Meishan) Co., Ltd. tau pom tias muaj ntau tshaj 140% ntawm tus qauv tus nqi. aflatoxin M1 cov (tus qauv tus nqi: <0.5 ug / kg /, ntsuas tus nqi: 1.2 ug / kg).

Nws tau nkag siab tias 18 yam khoom xws li txhuas, inorganic arsenic, tag nrho cov mercury, chromium, aflatoxin M1 thiab melamine nyob rau hauv cov kua mis nyuj cov khoom raug kuaj nyob rau hauv qhov chaw kuaj xyuas. Ob yam khoom ntawm aflatoxin M1 tau pom tias tsis ua raws li tus qauv. Ntxiv rau 250 ml cov kua mis ntshiab uas tsim los ntawm Mengniu Meishan Factory thaum Lub Kaum Hli 18, 2011, Fujian Changfu Dairy Co., Ltd. tau tsim 250 ml cov kua mis ntshiab (cov mis nyuj zoo) thaum Lub Kaum Hli 8, 2011 (tus qauv tus nqi: <0.5 ug / kg, ntsuas tus nqi: 0.9 ug / kg). Qhov no yog qhov teeb meem.

Tshaj tawm los ntawm Xinhua net, Guangzhou, Lub Xya Hli 22, 2012 (Xov Xwm Oudianqiu) Guangzhou Lub Chaw Haujlwm Saib Xyuas Kev Lag Luam thiab Kev Lag Luam tsis ntev los no tau tshaj tawm qhov thib ob kev sib txuas ntawm cov khoom siv mis nyuj thiab Dairy-Containing food sampling inspection in the second quarter of 2012, qhia tias tsib tus me nyuam mos mis hmoov los ntawm Hunan Xeev tau pom tias tsis zoo hauv cov ntsiab lus aflatoxin, ntawm plaub mis hmoov zaub mov txawv thiab cov khoom raug nominally tsim los ntawm Hunan Chang. Shayahua Dairy Co., Ltd., lub nominal ntau lawm chav tsev ntawm ib yam khoom yog Hunan Yahua Dairy tuav Co., Ltd.

Raws li cov ntaub ntawv tso tawm los ntawm Guangzhou Bureau of Industry thiab Commerce, lub nominal ntau lawm chav tsev yog Big Baby Formula Milk Powder nyob rau hauv Golden Suit ntawm Hunan Changsha Yahua Dairy Co., Ltd. (Tshooj 2) (Kev Lag Luam: Nanshan, specification: 400g / box , hnub tim: 2011-08-04; 2011-12-17), Baby Formula Mis Hmoov (Tshooj 3) (Kev Lag Luam: Nanshan, specification: 900) G / tank, hnub tsim khoom: 2011-08-08), Loj Baby Formula Milk Powder (Section 2) (Kev Lag Luam: Nanshan, specification: 400g/box, 2011-08 -23) tau pom tias tsis tsim nyog rau aflatoxin M1. Nws tau pom tias cov ntsiab lus ntawm aflatoxin M1 tsis yog raws li tus qauv hauv cov me nyuam mos mis hmoov loj ntawm Baihui (Section 2) ntawm Hunan Yahua Dairy Holding Co., Ltd. (Kev Lag Luam: Nanshan, specification: 700g / hnab, hnub tsim khoom: 2011-07-09).

Raws li Guangzhou Bureau of Industry thiab Commerce, aflatoxin M1 belongs rau mycotoxin thiab yog hydroxylated metabolite ntawm aflatoxin B1 nyob rau hauv cov tsiaj, uas yog heev lom thiab carcinogenic.

Lub sijhawm ntawd, Guangzhou Lub Chaw Haujlwm Saib Xyuas Kev Lag Luam thiab Kev Lag Luam tau ntsuas kev tshem tawm cov zaub mov tsis tsim nyog los ntawm cov txee, kaw nws, ua ntaub ntawv rau kev tshawb nrhiav thiab kev rau txim, Tiv Thaiv cov zaub mov tsis tsim nyog los ntawm kev nkag mus rau hauv kev ua lag luam.

Hauv xyoo 2014, raws li tsab ntawv ceeb toom ntawm Lub Xeev Kev Tswj Xyuas Khoom Noj thiab Tshuaj, 48 pawg ntawm 1565 cov qauv ntawm ntau hom tsis tsim nyog. Ntawm lawv, aflatoxin M1 tau kuaj pom hauv peb pawg ntawm cov khoom ntawm Shanxi Gucheng Dairy Group. Cov khoom lag luam tsis zoo tam sim no tau raug yuam kom rov qab, ob lub lag luam poob lawv cov ntawv tso cai me nyuam mos mis hmoov, thiab 10 lub lag luam thiab cov nyuj rancher nres ntau lawm thiab rectification. Qhov no yog thawj qhov kev tshaj tawm loj ntawm cov txiaj ntsig ntawm qhov chaw kuaj xyuas tom qab "kev sim lub neej thiab kev tuag" ntawm lub teb chaws mis nyuj hmoov tau ua nyob rau hauv 2014.

Aflatoxin yog qhov nyuaj rau tshem tawm thiab degrade, thiab cov txheej txheem degradation kuj nyuaj. Txoj kev siv tshuaj tua kab mob cua sov lossis pasteurization tsis muaj txiaj ntsig rau aflatoxin. Tam sim no, nws yooj yim dua los siv aflatoxin degrader hauv khw. Nws tuaj yeem degrade aflatoxin zoo yam tsis ua kom puas cov zaub mov qub los ntawm kev siv lub hauv paus ntsiab lus ntawm ultraviolet hluav taws xob.

Peb cov neeg zoo li cas tuaj yeem ua tau yog ua txoj haujlwm zoo ntawm kev tshawb xyuas thaum xaiv cov mis nyuj. Nws tsis tshua muaj kev xaiv aflatoxin ntau npaum li qhov ua tau. Muaj ob peb lub hauv paus ntsiab lus me me rau kev xaiv mis hmoov.

1. Xaiv cov mis nyuj yuav tsum yog cov mis nyuj zoo uas muaj kev nyab xeeb mis noj zaub mov muaj tseeb, cov mis nyuj zoo tsis tas yuav noj zaub mov kom cov mis nyuj muaj tsawg thiab tsawg dua hom aflatoxin.
2. Txhawm rau xaiv lub npe loj, kev tswj xyuas zoo ntawm lub npe loj feem ntau yog qhov zoo dua, thiab cov txheej txheem ntau lawm yog qhov muaj txiaj ntsig zoo dua. Tsis txhob khav theeb thiab pheej yig hauv kev xaiv qee yam "peb yam tsis muaj" cov khoom.
3. Nco ntsoov ua tib zoo saib xyuas cov mis hmoov dynamic, tsis txhob yuav teeb meem mis hmoov.
