He ture hou nō te EU kei te whai mana I te 28 o Noema 2022 (EU 2019/1871) i whai mana te ture hou nō Ūropi mō te tohutoro mahi (RPA) mō ngā matūkai nitrofuran. Mō ngā matūkai e mōhiotia ana ko SEM, AHD, AMOZ me AOZ, he RPA o te 0.5 ppb. I pā anō hoki tēnei ture ki te DNSH, te matūkai o Nifursol.
Ko te Nifursol he nitrofuran kua aukatia hei tāpiringa whāngai i te Kotahitanga o Ūropi me ētahi atu whenua. Ka hurihia te Nifursol ki te 3,5-dinitrosalicylic acid hydrazide (DNSH) i roto i ngā rauropi ora. Ko te DNSH he tohu mō te kitenga i te whakamahinga turekore o te nifursol i roto i te mahi ahuwhenua kararehe.
He whānuitanga hangai ngā nitrofuranngā paturopi, e whakamahia pinepine ana i roto i ngā kararehete whakaputanga mō tōna tino pai ki te patu huakita me tengā āhuatanga pharmacokinetic. I whakamahia hoki ēneihei kaiwhakatairanga tipu i roto i te poaka, te heihei me te waite whakaputa. I roto i ngā rangahau roa me ngā kararehe taiwhangai tohu ko ngā rongoā matua me ā rātou metabolitesi whakaatu i ngā āhuatanga whakaputa mate pukupuku me ngā āhuatanga whakaputa matū.Nā tēnei i aukatia ai ngā nitrofurans mōte maimoatanga o ngā kararehe e whakamahia ana mō te hanga kai.
Nā mātou o Beijing Kwinbon i whakawhanake i te kete whakamātautau Elisa me te rīpene whakamātautau tere o te DNSH, kua tino makona a LOD ki ngā ture hou a te EU.
