Umthetho omusha we-EU osebenzayo Umthetho Omusha waseYurophu wephoyinti lesenzo (RPA) we-nitrofuran metabolites wawusebenza kusukela zingama-28 Novemba 2022 (EU 2019/1871). Ngama-metabolites aziwayo i-SEM, AHD, AMOZ ne-AOZ i-RPA engu-0.5 ppb. Lo mthetho wawusebenza naku-DNSH, i-metabolite ye-Nifursol.
I-Nifursol iyi-nitrofuran evinjelwe njengesengezo sokuphakelayo e-European Union nakwamanye amazwe. I-Nifursol yenziwa i-3,5-dinitrosalicylic acid hydrazide (DNSH) ezintweni eziphilayo. I-DNSH iwuphawu lokutholwa kokusetshenziswa okungekho emthethweni kwe-nifursol ekufuyweni kwezilwane.
I-Nitrofuran iyi-synthetic broad-spectrumama-antibiotics, asetshenziswa kaningi ezilwaneniukukhiqizwa kwe-antibacterial yayo enhle kakhulu futhiizakhiwo ze-pharmacokinetic. Zase zisetshenzisiwe futhinjengabagqugquzeli bokukhula kwezingulube, izinkukhu kanye nezamanziukukhiqiza. Ezifundweni zesikhathi eside nezilwane zaselabhuibonise ukuthi izidakamizwa zomzali kanye nama-metabolites azoibonise izici ze-carcinogenic ne-mutagenic.Lokhu kuholele ekuvinjweni kwe-nitrofuranukwelashwa kwezilwane ezisetshenziselwa ukukhiqiza ukudla.
Manje thina i-Beijing Kwinbon sithuthukise ikhithi yokuhlola ye-Elisa kanye nomugqa wokuhlola osheshayo we-DNSH, i-LOD yaneliseke ngokuphelele ngomthetho omusha we-EU. Futhi sisathuthukisa imikhiqizo futhi sinciphisa isikhathi sokufukamela. Sizozama konke okusemandleni ethu ukulandela izinyathelo ze-EU futhi sinikeze izinsizakalo ezinhle kuwo wonke amakhasimende. Yamukela umbuzo wakho nabaphathi bethu bokuthengisa.
