Kugwa ni igihe cyo gusarura ibigori, muri rusange, iyo umurongo wamata yintete yibigori wabuze, igipande cyumukara kigaragara munsi, kandi nubushuhe bwintungamubiri bwintoki bugabanuka kurwego runaka, ibigori bishobora gufatwa nkibyera kandi byiteguye gusarura. Ibigori byasaruwe muri iki gihe ntabwo bitanga umusaruro mwinshi gusa kandi bifite ireme, ariko kandi bifasha kubika no gutunganya nyuma.
Ibigori bizwi nka kimwe mu binyampeke. Ariko, icyarimwe, ibigori birashobora kandi kuba birimo mycotoxine, harimo aflatoxine B1, vomitoxine na zearalenone, bishobora guhungabanya ubuzima bwabantu n’inyamaswa, bityo bikaba bisaba uburyo bunoze bwo gupima no gufata ingamba zo kugenzura umutekano n’ubuziranenge bwibigori na ibicuruzwa byayo.
1. Aflatoxin B1 (AFB1)
Ibyingenzi byingenzi: Aflatoxine ni mycotoxine isanzwe, muri yo aflatoxine B1 ni imwe muri mycotoxine ikwirakwizwa cyane, uburozi na kanseri. Ni physique-chimique ihamye kandi ikeneye kugera ku bushyuhe bwo hejuru bwa 269 ℃ kugirango isenywe.
Ibyago: Uburozi bukabije bushobora kugaragara nkumuriro, kuruka, kubura ubushake bwo kurya, jaundice, nibindi. Mugihe gikabije, asitite, kubyimba ingingo zo hepfo, hepatomegaly, splenomegaly, cyangwa se urupfu rutunguranye rushobora kubaho. Kunywa igihe kirekire aflatoxine B1 bifitanye isano no kwiyongera kwanduye kanseri yumwijima, cyane cyane ababana na hepatite bakunze kwibasirwa nigitero cya kanseri yumwijima.
2. Vomitoxine (Deoxynivalenol, DON)
Ibyingenzi byingenzi: Vomitoxine nubundi mycotoxine isanzwe, imiterere ya fiziki ya chimique irahagaze neza, ndetse no mubushyuhe bwo hejuru bwa 120 ℃, kandi ntabwo byoroshye kurimburwa mubihe bya acide.
Ibyago: Uburozi bugaragarira cyane cyane muri sisitemu yumubiri nibimenyetso bya sisitemu ya nervice, nko kugira isesemi, kuruka, kubabara umutwe, umutwe, kubabara mu nda, impiswi, nibindi, bamwe bashobora no kugaragara nkintege nke, kutamererwa neza muri rusange, gutemba, umuvuduko udahamye nibindi bimenyetso nka ubusinzi.
3. Zearalenone (ZEN)
Ibyingenzi byingenzi: Zearalenone nubwoko butari steroidal, mycotoxine ifite estrogeneque, imiterere ya fiziki ya chimique irahagaze, kandi kwanduza ibigori ni byinshi.
Ibyago: Bikora cyane cyane muburyo bw'imyororokere, kandi byumva cyane inyamaswa nk'imbuto, kandi bishobora gutera ubugumba no gukuramo inda. Nubwo nta makuru y’uburozi bw’abantu, abantu batekereza ko indwara z’abantu ziterwa na estrogene zishobora kuba zifitanye isano n’uburozi.
