Choyamba, nthunzi yotentha kwambiri imatha kupha mabakiteriya ndi ma virus. M'makampani ogulitsa zakudya, tableware ndi chinthu chomwe chimakhudzana ndi chakudya. Ngati tabuletiyo ilibe mankhwala ophera tizilombo toyambitsa matenda, mabakiteriya ndi ma virus amatha kufalikira ku chakudya, zomwe zimayambitsa matenda monga kupha chakudya. Jenereta ya nthunzi imatha kupha mabakiteriya ndi mavairasi pamtunda wa tableware kudzera muzitsulo zotentha kwambiri kuti zitsimikizire chitetezo cha chakudya.
Kachiwiri, gwiritsani ntchito jenereta ya nthunzi kuchotsa mafuta ndi madontho pa tableware. M'makampani ogulitsa zakudya, tableware nthawi zambiri imayipitsidwa ndi mafuta komanso madontho. Ngati sichitsukidwa ndi kutetezedwa ndi tizilombo toyambitsa matenda mu nthawi, sichidzangokhudza maonekedwe a tableware, komanso kubereka mabakiteriya ndi mavairasi. Jenereta ya nthunzi imatha kuchotseratu mafuta ndi madontho pamwamba pa tableware kupyolera mu mphamvu ya nthunzi yotentha kwambiri, kupanga tableware kuwoneka yatsopano.
Pomaliza, ma jenereta a nthunzi amatha kupulumutsa nthawi ndi ndalama zogwirira ntchito pothirira ma tableware.

Jenereta ya nthunzi imatha kufupikitsa kwambiri nthawi yophera tizilombo pogwiritsa ntchito njira yotsekera mwachangu ndi nthunzi yotentha kwambiri, komanso imachepetsa kudalira zotsukira, motero kupulumutsa nthawi ndi ndalama zogwirira ntchito.
Mwachidule, ma jenereta a nthunzi amagwira ntchito yofunika kwambiri pamakampani opanga zakudya. Ikhoza kupha bwino mabakiteriya ndi mavairasi, kuchotsa mafuta ndi madontho pa tableware, ndipo nthawi yomweyo kupulumutsa nthawi ndi ndalama zogwirira ntchito, kuonetsetsa chitetezo cha chakudya ndi ukhondo, ndikupatsa makasitomala malo odyera abwino.
