Zakudya za nyama ndi chimodzi mwazinthu zazikulu za mapuloteni omwe timadya. Mwambiwu umati, matenda amachokera mkamwa, kotero kuti mafakitale ambiri opangira nyama amasamala kwambiri zaukhondo ndi chitetezo. Komabe, nyama zili ndi mapuloteni ambiri ndipo nthawi zambiri zimakhala ndi ma virus. Kutsekereza nthunzi , kuchotsa kapena kuchotsa tizilombo toyambitsa matenda pa sing'anga yopatsirana; jenereta yotenthetsera yotentha kwambiri imapangitsa kuti ikwaniritse zofunikira zaulere, ndipo imalepheretsa kufalikira kwa mabakiteriya pamsonkhano wazogulitsa nyama.
Zakudya za nyama zimakhala ndi mapuloteni komanso mafuta ambiri ndipo ndizomwe zimapatsa mabakiteriya. Ukhondo panthawi yokonza nyama ndizofunikira kuti mutsimikizire kuti nyama ndi yabwino komanso yotetezeka. Pali magwero ambiri a kuipitsidwa ndi mabakiteriya popanga nyama. Magwero a kuipitsidwa monga madzi, mpweya ndi zipangizo zopangira ndizovuta ndipo zimaphatikizapo mbali zonse za ndondomekoyi. Choncho, kusankha njira yabwino yophera tizilombo toyambitsa matenda pokonza ndi kupanga nyama ndikofunika kwambiri kwa anthu komanso chakudya. Ndikofunikira kwambiri kugwiritsa ntchito nthunzi kuchokera pa jenereta ya nthunzi yopanda vuto popha tizilombo toyambitsa matenda.
Njira yochepetsera nthunzi imagwiritsidwa ntchito kwambiri, ndipo zinthu zonse zosamva chinyezi zimatha kutsekedwa ndi ma jenereta a nthunzi. Nthunzi yotentha kwambiri imakhala ndi malowedwe amphamvu komanso mphamvu yotseketsa. Nthunzi yotentha kwambiri imalowa mu chinthucho, imathamanga mofulumira ndikulimbitsa mabakiteriya mpaka kufa, zomwe zimatenga nthawi yochepa. Jenereta ya nthunzi imatembenuza mwachindunji madzi kukhala nthunzi yotentha kwambiri, yomwe ilibe zonyansa zina kapena mankhwala, kuonetsetsa chitetezo ndi kudyedwa kwa nyama yosabala.
Nobeth wakhala katswiri pa kafukufuku wa jenereta wa nthunzi kwa zaka 20 ndipo ali ndi bizinesi yopanga ma boiler a Class B, yomwe ndi chizindikiro chamakampani opanga ma jenereta. Jenereta ya Nobeth imakhala yogwira ntchito kwambiri komanso yaying'ono, ndipo safuna satifiketi yotentha. Ndiwoyenera m'mafakitale akuluakulu 8 kuphatikiza kukonza chakudya, kusita zovala, mankhwala azachipatala, uinjiniya wa biochemical, kafukufuku woyesera, makina oyikapo, kukonza konkire, komanso kuyeretsa kotentha kwambiri. Yatumikira makasitomala opitilira 200,000 onse, ndipo bizinesi yake ikukhudza mayiko ndi zigawo zopitilira 60 padziko lonse lapansi.
