Ikwindla lixesha lokuvunwa kombona, ngokubanzi, xa umgca wobisi wekhozo lombona unyamalala, umaleko omnyama uvela ezantsi, kwaye umxholo wokufuma wekhozo wehla uye kwinqanaba elithile, umbona ungathathwa njengovuthiweyo kwaye ulungele ukuvunwa. Umbona ovunyiweyo ngeli xesha awugcini nje ngokuba nesivuno esiphezulu kunye nomgangatho olungileyo, kodwa ukwanceda ekugcinweni nasekucutshungulweni okulandelayo.
Umbona uthandwa kakhulu njengenye yeenkozo ezisisiseko. Nangona kunjalo, kwangaxeshanye, umbona unokuba nezinye ii-mycotoxins, kuquka i-aflatoxin B1, i-vomitoxin kunye ne-zearalenone, ezinokuba yingozi kwimpilo yabantu neyezilwanyana, ngoko ke zifuna iindlela zokuvavanya ezisebenzayo kunye namanyathelo okulawula ukuqinisekisa ukhuseleko kunye nomgangatho wombona kunye neemveliso zawo.
1. I-Aflatoxin B1 (AFB1)
Iimpawu eziphambili: I-Aflatoxin yi-mycotoxin eqhelekileyo, apho i-aflatoxin B1 yenye yezona mycotoxins zixhaphakileyo, zinobuthi kwaye zibangela umhlaza. Izinzile kwi-physicochemical kwaye kufuneka ifikelele kubushushu obuphezulu be-269℃ ukuze itshatyalaliswe.
Iingozi: Ityhefu ebukhali ingabonakala njengomkhuhlane, ukuhlanza, ukungabi namdla wokutya, i-jaundice, njl. Kwiimeko ezinzima, i-ascites, ukudumba kwamalungu asezantsi, i-hepatomegaly, i-splenomegaly, okanye nokufa ngequbuliso kunokwenzeka. Ukutya i-aflatoxin B1 ixesha elide kunxulunyaniswa nokwanda kwenani lomhlaza wesibindi, ingakumbi abo bane-hepatitis basengozini enkulu yokuhlaselwa yiyo kwaye babangele umhlaza wesibindi.
2. I-Vomitoxin (i-Deoxynivalenol, i-DON)
Iimpawu eziphambili: I-Vomitoxin yenye i-mycotoxin eqhelekileyo, iipropati zayo ze-physicochemical zizinzile, nokuba kubushushu obuphezulu be-120 ℃, kwaye akulula ukuyitshabalalisa phantsi kweemeko ze-asidi.
Iingozi: Ityhefu ibonakala kakhulu kwiimpawu zenkqubo yokugaya ukutya kunye neempawu zenkqubo yemithambo-luvo, ezifana nokucaphuka, ukuhlanza, intloko ebuhlungu, isiyezi, iintlungu zesisu, urhudo, njl.njl., ezinye zinokubonakala zibuthathaka, ukungonwabi ngokubanzi, ukurhawuzelela, isantya esingazinzanga kunye nezinye iimpawu ezifana nokunxila.
3. I-Zearalenone (i-ZEN)
Iimpawu eziphambili: I-Zearalenone luhlobo lwe-non-steroidal, i-mycotoxin eneempawu ze-estrogenic, iimpawu zayo ze-physicochemical zizinzile, kwaye ungcoliseko lwayo embona luxhaphake kakhulu.
Iingozi: Isebenza kakhulu kwinkqubo yokuzala, kwaye inovelwano kakhulu kwizilwanyana ezifana neemazi, kwaye inokubangela ukungazali kunye nokukhupha isisu. Nangona kungekho ngxelo zetyhefu ebantwini, kukholelwa ukuba izifo zabantu ezinxulumene ne-estrogen zinokunxulunyaniswa netyhefu.
