O se vailaau fa'ama'i fa'ama'i ose masini e fa'aogaina ai le vevela, vaila'au, po'o le fa'avevela e tape ai pe fa'aumatia ai ituaiga uma o meaola ninii ma pathogens mai meafaigaluega fa'afoma'i ma mea faigaluega.Ose meafaigaluega taua i so'o se tulaga tau soifua maloloina, aua e fesoasoani e puipuia le sosolo o fa'ama'i ma fa'ama'i.Ole fa'agasologa ole fa'ama'i e fa'amautinoa ai fo'i e saogalemu meafaigāluega fa'afoma'i e fa'aoga ile gasegase.E 'ese'ese ituaiga fa'ama'i fa'afoma'i, e aofia ai autoclaves, vaila'au fa'ama'i, ma fa'amalama fa'avevela.Autoclaves e fa'aogaina le ausa ma le mamafa e fa'amama ai meafaigāluega, a'o vaila'au fa'amalama e fa'aaogaina vaila'au e pei ole ethylene oxide.E fa'aogaina e mea fa'ama'i fa'avevela e fa'amate ai meaola ninii.E mana'omia e vaila'au fa'ama'i fa'ama'i le tausiga lelei ma le mata'ituina ina ia mautinoa o lo'o tumau lelei.
