Yahimbwe n'umuhanga mu Bufaransa Louis Pasteur mu kinyejana cya cumi n'icyenda. Mu 1864, Pasteur yavumbuye ko gushyushya byeri na divayi byari bihagije kugira ngo bice bagiteri nyinshi zangiza, bituma ibyo binyobwa bidahinduka. Inzira ibigeraho ikuraho mikorobe zitera no kugabanya umubare wa mikorobe kugirango wongere ubwiza bwibinyobwa.

Bitandukanye na sterisizione, pasteurisation ntabwo igamije kwica mikorobe zose ziri mu biryo. Ahubwo, igamije kugabanya umubare w’indwara ziterwa na virusi ku buryo bidashoboka ko zitera indwara (tuvuge ko ibicuruzwa bya pasteurized bibitswe nkuko byerekanwe kandi bikoreshwa mbere yitariki yo kurangiriraho). Ubucuruzi-bunini bwo guhagarika ibiryo ntibisanzwe kuko bigira ingaruka mbi kuburyohe nubwiza bwibicuruzwa. Ibiribwa bimwe na bimwe, nkibikomoka ku mata, imbuto zimbuto zirashobora gushyuha cyane kugirango mikorobe zitera indwara zangirike.
