Vuba aha, insanganyamatsiko yauburozi bwa aflatoxinGuhinga ku duce twakonjeshejwe nyuma yo kubibika iminsi irenga ibiri byateye impungenge abaturage. Ese kurya uduce twakonjeshejwe hakoreshejwe umwuka ni byiza? Ni gute uduce twakonjeshejwe twagombye kubikwa mu buryo bwa siyansi? Kandi ni gute twakwirinda ibyago byo kwandura uburozi bwa aflatoxin mu buzima bwa buri munsi? Abanyamakuru basabye igenzura kuri ibi bibazo.
"Uduce dukonjeshejwe dushyushye ntabwo dukora aflatoxin mu bihe bisanzwe, kuko aflatoxin ikorwa ahanini n'udusimba nka Aspergillus flavus mu duce dushyuha cyane kandi dufite ubushyuhe bwinshi. Ahantu hakonje (hafi -18°C) ntabwo hatuma udusimba twiyongera," ibi byavuzwe na Wu Jia, Umunyamabanga Mukuru Wungirije w'Ishami ry'Ubushakashatsi ku Mirire mu Ishyirahamwe ry'Ubushinwa rishinzwe guteza imbere Ubuzima n'Uburezi. Niba udusimba dukonjeshejwe twamaze kwanduzwa n'udusimba mbere yo gukonjeshwa, uburozi bw'udusimba ntibuzakurwaho nubwo twaba dukonjeshejwe. Kubwibyo, udusimba dukonjeshejwe dushyushye kandi tutarakonjeshwa mbere yo gukonjeshwa dushobora kuribwa neza. Niba udusimba dukonjeshejwe dufite impumuro idasanzwe, ibara rihinduka, cyangwa ubuso budasanzwe nyuma yo gushonga, tugomba kujugunywa kugira ngo twirinde kuribwa.
Dukurikije "Indyo n'Isuku y'Ibiribwa," aflatoxin ni ubwoko bw'ibinyabutabire bikorerwa muri Aspergillus flavus na Aspergillus parasiticus, ibi bikaba ari ibihumyo bikunze kugaragara mu binyampeke no mu biryo by'amatungo. Mu Bushinwa, Aspergillus parasiticus ni gake cyane. Ubushyuhe bwa Aspergillus flavus bwo gukura no gukora aflatoxin ni 12°C kugeza 42°C, ubushyuhe bwiza bwo gukora aflatoxin ni 25°C kugeza 33°C, naho agaciro k'amazi ni 0.93 kugeza 0.98.
Uburozi bw'ibihumyo bukorwa ahanini n'ibihumyo mu bidukikije bishyushye kandi bikonje. Gufata ingamba mu buzima bwa buri munsi bishobora kugabanya ibyago byo kwandura no kunywa uburozi bw'ibihumyo. Impuguke zitanga inama yo guhitamo ibirango n'abacuruzi bemewe mu gihe ugura ibiryo kugira ngo urebe ko ari bishya kandi birangwa n'umutekano. Mu gihe ubika ibiryo, ugomba kwita ku gihe cyo kubibika, kandi ibiryo bigomba kubikwa ahantu humutse, hafite umwuka mwiza, kandi hijimye kugira ngo ugabanye amahirwe yo gukura kw'ibihumyo. Ni ngombwa cyane kumenya ko kubika ibiryo muri firigo atari uburyo bworoshye, kuko ibiryo bigira igihe cyiza cyo kubibika. Mu gihe cyo gutunganya no guteka ibiryo, ibiryo bigomba kozwa neza, kandi hagakurikiranwa uburyo bwo kubiteka.
Byongeye kandi, bitewe n’ubushyuhe bwiza bwa aflatoxin, ntabwo byoroshye kubora iyo utetse cyangwa ushyushye bisanzwe. Ibiryo bifite ibihumyo bigomba kwirindwa, kandi nubwo igice gifite ibihumyo cyakurwaho, ibisigaye ntibigomba kuribwa. Byongeye kandi, ubukangurambaga ku isuku y’ibiribwa bukwiye kongerwa, kandi ibikoresho byo mu gikoni nk’uduti two gukata n’ibibaho byo gukata bigomba gusukurwa vuba kandi bigasimbuzwa buri gihe kugira ngo hirindwe ko ibihumyo na bagiteri byakwiyongera.
Ku bijyanye no kubika mu buryo bwa siyansi utubuto twatetse mu muriro, Wu Jia yavuze ko kubika mu muriro wa firigo ari bwo buryo bwizewe kandi buryoshye cyane. Ariko, ni ngombwa kumenya ko utubuto twatetse mu muriro tugomba gupfundikirwa mu mifuka y'ibiribwa cyangwa mu gipfunyika cya pulasitiki kugira ngo wirinde ko umwuka ugera, wirinde ko amazi yashira, kandi wirinde kwanduzwa n'impumuro mbi. Utubuto twatetse mu muriro tutandujwe n'ibihumyo dushobora kuribwa mu mezi atandatu iyo tubitswe ahantu hakonje munsi ya -18°C. Mu hantu hakonjeshejwe, dushobora kubikwa umunsi umwe cyangwa ibiri ariko nanone tugomba gupfundikirwa kugira ngo wirinde ubushuhe.
