Ibiribwa mugikorwa cyo gutunganya, kubika no gutunganya, intungamubiri yibiribwa bizagira ingaruka zitandukanye zingaruka mbi, kandi bigafata ingamba zo gupakira, ikigamijwe nukugenzura no guhindura ibyo bintu bibi byangiza ibiryo. Ibintu bipfunyika bishobora kugenzura, nkurumuri rwumucyo (cyane cyane ultraviolet), kwibanda kuri ogisijeni, guhinduka kwubushuhe, gutwara ubushyuhe, gukwirakwiza ibice bimwe mubiribwa, kwangirika kwumubiri nubukanishi byangiza ibiryo nudukoko no gutera mikorobe, nibindi.
Impuzandengo ya pulasitike irashobora gufata hagati yimyaka 15 na 1.000 kugirango ibore, kandi mugihe ubikora, irekura imiti yuburozi, yangiza inyamaswa nubutaka dukeneye kugirango tubashe kubaho.
. Guhindura imiti, kwemeza ubwiza bwibiryo murwego rwo gutembera neza, kongera igihe cyigihe cyibiribwa nigihe cyo guhunika.
(2) Irinde ibiryo kwanduzwa na mikorobe yo hanze n'umwanda. Inzira nogukwirakwiza ibiryo kuva muruganda kugeza mumaboko yabaguzi biragoye cyane, kandi hariho amahirwe menshi yo kwanduza. Igiteye ubwoba cyane ni kwanduza kwa kabiri ningemwe nziza zitera indwara nka Clostridium na Clostridium botulinum, zishobora gutera uburozi kubaguzi. Kubwibyo, gupakira gushyira mu gaciro no kugira isuku birashoboka rwose gukuraho amahirwe yo kwanduza hanze.
. Ibi ntibishobora kuzigama imirimo gusa, ahubwo binagabanya amahirwe yo kwanduzwa mugihe cyo gupakira no kunoza umusaruro. Muri icyo gihe, ibiryo bipfunyitse bikozwe na mashini na automatike birasa kandi birasanzwe kuruta ibyakozwe nintoki, bitanga uburyo bwiza bwo gushushanya imiterere yapakirwa ubwikorezi, hamwe nuburyo bwo gutwara no guhunika.
Izi mpinduka zimyitwarire zigira ingaruka zikomeye kumafunguro yatanzwe muburyo n'ubwoko.
