Kushivirira Kupisa uye Kubvisa Kuvharwa Kwemasero Mamiriro Ezvinhu Zvinosvibisa Zvirwere Zvidiki Mutsika Yemasero
Zvipembenene zvinowanzo svibisa masero zvinosanganisiraEscherichia coli, Staphylococcus aureus, mbiriso, chakuvhuvhu, mycoplasma nemavhairasi. Zvipembenene izvi zvinogona kumiswa mumamiriro api ezvinhu?
1) Escherichia coli
E. colihaipindi kupisa zvakanyanya. Kunyika mumvura inopisa pa60°C kwemaminitsi makumi matatu kunoita kuti isaparadzwe; kupisa pa70°C kwemaminitsi matatu kunouraya mabhakitiriya; mvura inopisa pa100°C inoita kuti asashande mukati memaminitsi 1 kusvika ku3.
2) Staphylococcus aureus
Masero emiti asina sporesS. aureusdzine mwero wekutsungirira kupisa uye hadzigoni kutsungirira tembiricha yakakwira. Kugeza nemvura ye60°C kwemaminitsi makumi matatu kunobvisa mabhakitiriya akawanda anoshanda; kurapwa pa70°C kwemaminitsi gumi kunodzima zvachose masero emiti.
3) Mbiriso
Masero embiriso anowanzomira kukura pamusoro pe47°C. Tembiricha yepamusoro yekukura kwawo inotangira pa20°C kusvika 30°C, uye tembiricha yepamusoro yekuvirisa ndeye40–42°C. Masero embiriso anourayiwa mukati memaminitsi pa55–56°C.
4) Foroma
Zvipembenene zvinogara zviri nyore uye zvinoberekana munzvimbo dzine rima, dzine hunyoro pa20–30°C. Kupisa zvipembenene zvakawanda kusvika 80°C uye kugara kwemaminitsi makumi maviri kunoita kuti zvisaparadzwe. Zvisinei, zvipembenene zvechipembenene (reproductive propagules) hazvipise kupisa uye zvakaoma kubvisa nemvura inopisa pa100°C; kurapwa nekupisa kwakanyanya pa121°C kwemaminitsi angangoita gumi kunogona kudzivirira zvipembenene.
5) Mycoplasma
Mycoplasma mabhakitiriya ari nyore asina madziro emasero uye anozivikanwa semabhakitiriya madiki anongozviunganidza ega (anowanzova 0.1–0.3 μm mudhayamita). Tembiricha yakanaka yekukura kwawo i35°C, uye anonzwa kupisa zvakanyanya. Kusangana ne100°C kwemaminitsi mashanu kunouraya mycoplasma zvachose.
6) Mavhairasi
Mavhairasi anowanzo kanganiswa nekupisa. Mavhairasi mazhinji anodzima kushanda mushure memaminitsi makumi matatu pa55–60°C, uye masekondi mashoma chete ekufashaira pa100°C anokwana kuti adzima kushanda zvizere.
