Ponena za mankhwala, imatha kupangidwa kukhala makapisozi kapena mankhwala opangidwa pakamwa kuti ichiritse matenda opatsirana a m'mimba ndi m'matumbo, ndipo ingagwiritsidwenso ntchito pochiza ndi kupewa kutentha thupi, malungo ndi chimfine.

1. Amagwiritsidwa ntchito ngati zonunkhira pa chakudya. Amagwiritsidwa ntchito makamaka mu zokometsera monga Supu, supu ya nyama, zinthu zopangidwa ndi mazira ndi masoseji ndi zina zotero.

2. Itha kugwiritsidwa ntchito ngati mankhwala ophera tizilombo toyambitsa matenda achilengedwe kuti tipewe ndikuchiritsa matenda a bala.

3. Mu ulimi wa ziweto:

1) Mankhwala ophera tizilombo toyambitsa matenda achilengedwe —- amatha kupewa ndikuchiza matenda m'mimba mwa nyama, monga Escherichia coli, Salmonella, Pasteurella, Staphylococcus, Streptococcus, coccidioides ndi matenda ena.

2) chosungira zachilengedwe —-kukula kwa tizilombo toyambitsa matenda, poizoni wotsutsana ndi flavase, zotsatira zake zotsutsana ndi antioxidants, Kuteteza kuwonongeka kwa chakudya.

3) bwino kuposa maantibayotiki —- palibe zotsalira, palibe kuipitsa, tizilombo toyambitsa matenda sitipanga kukana kwake, komanso kusagwirizana kwa maantibayotiki.

4) ndalama zabwino —- kugwiritsa ntchito nthawi yayitali kungathandize kusintha kuchuluka kwa chakudya, komanso kukulitsa kukula kwa ziweto.

Mu makampani opanga zodzoladzola —- zingagwiritsidwe ntchito ngati zinthu zopangira zinthu zosamalira khungu ndi zinthu zokongoletsera, zopha mabakiteriya, zotsutsa kutupa, komanso zokongoletsa khungu.

Mu makampani azakudya —- monga kukoma kwachilengedwe komanso chosungira zinthu.
