Mitemo mitsva yeEU iri kumanikidza New European mutemo wereferensi point of action (RPA) yenitrofuran metabolites yanga iri kushanda kubva 28 Mbudzi 2022 (EU 2019/1871). Kune inozivikanwa metabolites SEM, AHD, AMOZ uye AOZ a RPA ye0.5 ppb. Uyu mutemo waishandiswawo kuDNSH, iyo metabolite yeNifursol.

Nifursol is nitrofuran yakarambidzwa sekuwedzera kwekudya muEuropean Union nedzimwe nyika. Nifursol inogadziriswa kusvika ku3,5-dinitrosalicylic acid hydrazide (DNSH) mune zvipenyu. DNSH chiratidzo chekuonekwa kwekushandiswa zvisiri pamutemo kwenifursol mukuchengeta mhuka.

Nitrofurans ndeyekugadzira yakakura-spectrumantibiotics, iyo inowanzoshandiswa mumhukakugadzirwa kweakanakisa antibacterial uyepharmacokinetic properties. Dzakanga dzashandiswawosevanokurudzira kukura munguruve, huku uye mumvuraproduction. Muzvidzidzo zvenguva refu nemhuka dzerabhoritariyakaratidza kuti mishonga yevabereki uye metabolites yavoyakaratidza carcinogenic uye mutagenic maitiro.Izvi zvakakonzera kurambidzwa kwe nitrofurans kunekurapwa kwemhuka dzinoshandiswa kugadzira chikafu.

Iye zvino isu Beijing Kwinbon takagadzira Elisa test kit uye nekukurumidza bvunzo tambo yeDNSH, LOD inogutsikana zvachose neEU mutemo mutsva. Uye isu tichiri kusimudzira zvigadzirwa uye kuderedza incubating nguva. Tichaedza nepatinogona napo kutevera matanho eEU uye nekupa akanakisa masevhisi kune vese vatengi. Gamuchira kubvunza kwako nevatungamiriri vedu vekutengesa.
