<prompt> Pfupisa nyaya yacho: Kuviriswa nezvokudya kunotapura mumwe muvanhu vatanhatu vokuAmerica gore rimwe nerimwe kunoparirwa nenyama nemiriwo zviri kuora, mvura yakasviba uye makicheni asina utsanana. Asi unyanzvi hutsva hunoshandisa magetsi nemvura bedzi rimwe zuva hungaita kuti zvokudya zvive zvakachengeteka zvikuru, pasina kukuvadza mhoteredzo. Vanzveri vanotaura kuti madonhwe maduku-duku emvura ine simba remagetsi akazadzwa nemasikirini akasununguka anogona kupfapfaidzwa pazvokudya kuti auraye utachiona hunovanda pamusoro. Masayendisiti paHarvard University muCambridge, Massachusetts anotenda kuti kana pakaitwa tsvakurudzo yakawanda, madonhwe anonzi Engineered Water Nanostructures EWNS anogona kutsiva nzira dziri kushandiswa iye zvino dzokuuraya utachiona muzvokudya, dzakadai sokushandisa mvura ine bleach uye chlorine. Michero nemiriwo zvinogona kusvibiswa nezvinhu zviduku zvinokonzera zvirwere chero kupi zvako muketani yavo yokugadzira, kutanga mumunda kana kuti mubindu rezvibereko, panguva yokukohwa, kutakura, kugadzira, kugovera, uye kutengesa, kana kuti panguva yokugadzirira mumasangano anogovera zvokudya uye mumusha kubva papurazi kuenda kumugwagwa wokupa zvokudya, vanonyora kudaro masayendisiti mufundo yavo, yakabudiswa mumagazini inonzi Environmental Science and Technology. Zvinogona kukonzera zvirwere zvinosanganisira mvura yekudiridza yakasvibiswa, mhuka, shiri, zvipembenene, ivhu, manyoro, uye vashandi vane utachionavanobata zvokudya. Zvichienderana nokuti michero nemiriwo zvainge zvasvibiswa nanoparticles kwenguva yakareba sei, kuongororwa kwakaitwa kwakaratidza kuti mabhakitiriya ari pakati pe80 ne98 muzana akanga aparadzwa. SEM mufananidzo weE. coli unoratidzwa. Funga nezvokupindwa nechepfu nezvokudya uye ungakurumidza kufunga kuti nyama mbishi ndiyo ine mhaka. Asi michero nemiriwo zvisati zvagadzirwa kana kuti zvakagadzirwa zvishomanana zvinogona kuva tsime remabhakitiriya, mavhairasi, uye tupukanana. Gore rimwe nerimwe muUnited States, vanhu vanenge mamiriyoni 48 vanorwara, 128 000 vanoiswa muchipatara, uye 3 000 vanofa nezvirwere zvinokonzerwa nezvokudya. Pakati pa1990 na2005,...  <response>: Nyanzvi dzakagadzira madonhwe dzichishandisa mvura ine simba remagetsi uye masimba akasununguka. Kana zvikasaswa pamichero nemiriwo, zvinogona kuuraya mabhakitiriya anosvika 98. E. coli, Salmonella neListeria zvakaedzwa muedzo pamadomasi. Nzira yacho rimwe zuva inogona kutsiva nzira dzazvino dzokuuraya utachiona hwezvokudya.
