Txoj cai lij choj tshiab ntawm EU uas siv tau Txoj cai lij choj tshiab ntawm European rau qhov chaw siv (RPA) rau cov metabolites nitrofuran tau siv txij li hnub tim 28 Kaum Ib Hlis 2022 (EU 2019/1871). Rau cov metabolites paub SEM, AHD, AMOZ thiab AOZ RPA ntawm 0.5 ppb. Txoj cai lij choj no kuj siv tau rau DNSH, cov metabolite ntawm Nifursol.
Nifursol yog ib qho nitrofuran uas raug txwv tsis pub siv ua khoom noj pub rau tsiaj hauv European Union thiab lwm lub tebchaws. Nifursol raug hloov mus ua 3,5-dinitrosalicylic acid hydrazide (DNSH) hauv cov tsiaj txhu uas muaj sia. DNSH yog ib qho cim qhia txog kev siv nifursol tsis raug cai hauv kev yug tsiaj.
Nitrofurans yog cov tshuaj synthetic broad-spectrumtshuaj tua kab mob, uas feem ntau siv rau hauv cov tsiaj txhukev tsim khoom rau nws cov tshuaj tua kab mob zoo heev thiabcov khoom pharmacokinetic. Lawv kuj tau sivua cov tshuaj txhawb kev loj hlob hauv npua, nqaij qaib thiab dejkev tsim khoom. Hauv kev tshawb fawb ntev nrog cov tsiaj hauv chav kuajqhia tau hais tias cov tshuaj niam txiv thiab lawv cov metabolitestau pom cov yam ntxwv carcinogenic thiab mutagenic.Qhov no ua rau muaj kev txwv tsis pub siv nitrofurans rau cov kab mob no.kev kho cov tsiaj siv rau kev tsim khoom noj.
Tam sim no peb Beijing Kwinbon tau tsim cov khoom siv kuaj Elisa thiab cov ntawv kuaj sai ntawm DNSH, LOD txaus siab rau EU txoj cai tshiab. Thiab peb tseem tab tom hloov kho cov khoom thiab txo lub sijhawm incubation. Peb yuav sim peb qhov zoo tshaj plaws los ua raws li EU cov kauj ruam thiab muab cov kev pabcuam zoo rau txhua tus neeg siv khoom. Txais tos koj cov lus nug nrog peb cov thawj coj muag khoom.
