Umthetho omtsha we-EU usebenza Umthetho omtsha waseYurophu wenqaku lokusebenza (RPA) kwi-nitrofuran metabolites wawusebenza ukususela nge-28 kaNovemba 2022 (EU 2019/1871). Kwi-metabolites ezaziwayo i-SEM, i-AHD, i-AMOZ kunye ne-AOZ i-RPA ye-0.5 ppb. Lo mthetho wawusebenza nakwi-DNSH, i-metabolite ye-Nifursol.

I-Nifursol yi-nitrofuran engavumelekanga njengesongezelelo sokondla kwi-European Union nakwamanye amazwe. I-Nifursol inyibilikiswa kwi-3,5-dinitrosalicylic acid hydrazide (DNSH) kwizinto eziphilayo. I-DNSH luphawu lokufumanisa ukusetyenziswa okungekho mthethweni kwe-nifursol ekukhuliseni izilwanyana.

IiNitrofurans zizinto ezibanzi ezenziwe ngokwenziwaii-antibiotics, ezisetyenziswa rhoqo kwizilwanyanaimveliso yayo ngenxa yokuba inamandla okulwa neentsholongwane kunyeIipropati ze-pharmacokinetic. Zikwasetyenziswanjengabakhuthazi bokukhula kwehagu, iinkukhu kunye nezilwanyana zasemanziniimveliso. Kwizifundo zexesha elide kwizilwanyana zaselabhoratrikubonise ukuba amayeza angabazali kunye neemetabolites zawobabonakalise iimpawu ezibangela umhlaza kunye ne-mutagenic.Oku kukhokelele ekubeni kuthintelwe ukusetyenziswa kwe-nitrofurans kwizifo zesisu.unyango lwezilwanyana ezisetyenziselwa ukuvelisa ukutya.

Ngoku thina eBeijing Kwinbon siphuhlise ikhithi yovavanyo lwe-Elisa kunye nomcu wovavanyo olukhawulezayo lwe-DNSH, i-LOD yanelisekile ngokupheleleyo ngumthetho omtsha we-EU. Kwaye sisaphucula iimveliso kwaye sinciphisa ixesha lokufukamela. Siza kuzama konke okusemandleni ethu ukulandela amanyathelo e-EU kwaye sinikezele ngeenkonzo ezintle kubo bonke abathengi. Wamkele umbuzo wakho kubaphathi bethu bezentengiso.
