Igihe cy'impeshyi ni igihe cyo gusarura ibigori, muri rusange, iyo umurongo w'amata w'imbuto z'ibigori ubuze, hakagaragara urwego rw'umukara hasi, kandi ubushuhe bw'imbuto bugagabanuka ku rwego runaka, ibigori bishobora gufatwa nk'aho byeze kandi byiteguye gusarurwa. Ibigori bisarurwa muri iki gihe ntabwo bitanga umusaruro mwinshi gusa kandi bifite ubwiza bwiza, ahubwo binafasha mu kubika no gutunganya nyuma.
Ibigori bikunzwe cyane nk'imwe mu mbuto z'ibanze. Ariko, icyarimwe, ibigori bishobora kuba birimo zimwe mu mycotoxin, harimo aflatoxin B1, vomitoxin na zearalenone, zishobora guteza akaga ku buzima bw'abantu n'inyamaswa, bityo bikaba bisaba uburyo bwiza bwo gupima no kugenzura kugira ngo harebwe umutekano n'ubuziranenge bw'ibigori n'ibikomoka kuri byo.
1. Uburozi bwa Aflatoxin B1 (AFB1)
Ibiranga by'ingenzi: Aflatoxin ni mycotoxin isanzwe, aho aflatoxin B1 ari imwe muri mycotoxins zikunze kugaragara, zirimo uburozi kandi zitera kanseri. Irahinduka mu buryo busanzwe kandi igomba kugera ku bushyuhe buri hejuru bwa 269°C kugira ngo irimburwe.
Ingaruka: Uburozi bukabije bushobora kugaragara nko kugira umuriro, kuruka, kubura ubushake bwo kurya, umuhondo, nibindi. Mu bihe bikomeye, ascites, kubyimba kw'amaguru yo hasi, hepatomegaly, splenomegaly, cyangwa ndetse n'urupfu rutunguranye bishobora kubaho. Gufata aflatoxin B1 igihe kirekire bifitanye isano no kwiyongera k'ubwiyongere bw'indwara ya kanseri y'umwijima, cyane cyane abafite hepatitis baba bashobora kwibasirwa cyane nayo kandi ikabatera kanseri y'umwijima.
2. Vomitoxin (Deoxynivalenol, DON)
Ibiranga by'ingenzi: Vomitoxin ni indi mycotoxin isanzwe, imiterere yayo ya fizikiki irahamye, ndetse no ku bushyuhe bwinshi bwa 120 ℃, kandi ntibyoroshye kuyirimbura mu gihe hari aside.
Ingaruka: Uburozi bugaragarira cyane cyane mu bimenyetso by’igogora n’iby’imitsi, nko kugira isesemi, kuruka, kuribwa umutwe, isereri, kubabara mu nda, impiswi, nibindi, bimwe bishobora no kugaragara nk’intege nke, kubabara muri rusange, kunyara, kudakora neza n’ibindi bimenyetso nko gusinda.
3. Zearalenone (ZEN)
Ibiranga by'ingenzi: Zearalenone ni ubwoko bwa mycotoxin idakoresha steroide, ifite imiterere ya estrogeni, imiterere yayo ya fizikiki irahoraho, kandi umwanda wayo mu bigori ukunze kugaragara cyane.
Ingaruka: Ikora cyane cyane ku buryo bw'imyororokere, kandi ikaba yoroshye cyane ku nyamaswa nk'ingurube, kandi ishobora gutera ubugumba no gukuramo inda. Nubwo nta raporo zigaragaza uburozi bw'abantu, bikekwa ko indwara ziterwa na estrogen ku bantu zishobora kuba zifitanye isano n'uburozi.
