Nitrous oxide, e masani ona taʻua o le kesi talie, ua faʻaaogaina mo faʻamoemoega eseese e aofia ai togafitiga faafomaʻi ma meaʻai. Ae ui i lea, o loʻo i ai le eseesega tele i le va o fomaʻi nitrous oxide ma meaʻai nitrous oxide e taua le malamalama.
Nitrous oxide (N2O) ose kasa e le lanu, e le mu ma sina manogi suamalie ma le tofo. Ua fa'aaogaina mo le silia ma le seneturi i nofoaga fa'afoma'i ma nifo e fai ma vai fa'ama'i ma fa'amama. E le gata i lea, o loʻo faʻaaogaina i le alamanuia o meaʻai e avea o se faʻamalosi i totonu o faʻamaʻi kulimi sasa ma i le gaosiga o nisi mea taumafa.
Ole nitrous oxide ile vasega faafoma'i e gaosia ma fa'amamāina e fa'amalieina tulaga fa'ata'atia e fa'atulafonoina lala sooupu e pei ole United States Pharmacopeia (USP) po'o le European Pharmacopoeia (Ph. Eur.). E faia ni su'esu'ega ma'oti ina ia mautinoa e sa'oloto mai mea leaga ma fa'aleaga, ma saogalemu ai mo le fa'aogaina i togafitiga fa'afoma'i. Ole nitrous oxide ile vasega faafoma'i e masani ona fa'aogaina mo le puleaina o tiga ile taimi ole togafitiga fa'afoma'i laiti ma togafitiga o nifo.
Ae o lesi foi itu,mea'ai fua nitrous oxideo lo'o gaosia fa'apitoa mo le fa'aoga i mea tau kuka. E masani ona faʻaaogaina e fai ma faʻamalosi i totonu o apa aerosol e fai ai kulimi sasa ma isi foam. Ole nitrous oxide ole mea'ai e fa'atulafonoina e le pulega o le saogalemu o mea'ai ina ia mautinoa e ausia tulaga mama mo le taumafaina. E ui lava e saogalemu mo le faʻaaogaina i sauniuniga o meaʻai, e le talafeagai mo le faʻaaogaina o fomaʻi poʻo nifo ona o le ono iai o mea leaga.
O le eseesega muamua i le va o foma'i nitrous oxide ma mea'ai vasega nitrous oxide o lo'o taoto i lo latou mama ma fa'amoemoe e fa'aoga. Ole nitrous oxide ole vasega ole foma'i e faia ni faiga fa'amama ma su'ega e fa'amautinoa ai e ausia tulaga maualuga mo talosaga fa'afoma'i. E taua tele mo le saogalemu o tagata ma'i e na'o le nitrous oxide e fa'asoifua maloloina e fa'aaogaina i nofoaga tau soifua maloloina e aloese ai mai lamatiaga fa'alesoifua maloloina e feso'ota'i ma mea leaga.
I se fa'afeagai, o mea'ai fa'ailoga nitrous oxide ua mamanuina fa'apitoa mo le fa'aogaina o mea'ai ma usita'ia tulafono fa'atonu e le pulega o le saogalemu o mea'ai. E ui atonu e saogalemu mo le taumafaina pe a faʻaaogaina i sauniuniga o meaʻai, e le talafeagai mo faʻamoemoega faʻafomaʻi ona o le ono iai o mea faʻaleagaina e ono lamatia ai le soifua maloloina i tagata mamaʻi.
O le fa'aogaina o le togi talafeagai o le nitrous oxide e taua tele mo le fa'amautinoaina o le saogalemu i tulaga fa'afoma'i ma mea'ai. E tatau i fomaʻi faʻapitoa ona tausisi i taʻiala ma tulafono faatonutonu pe a faʻaaogaina le nitrous oxide mo faʻamaʻi poʻo le puleaina o tiga e faʻaitiitia ai le lamatiaga o aʻafiaga leaga i tagata mamaʻi. E fa'apena fo'i, e tatau i fa'apolofesa o mea'ai taumafa ona fa'amautinoa o lo'o fa'aogaina fa'atatau i mea'ai nitrous oxide e tusa ai ma tulaga fa'ata'atia mo le saogalemu o mea'ai e puipuia ai so'o se lamatiaga e ono a'afia ma le fa'aleagaina.
E taua foi mo tagata faʻatau le nofouta i le eseesega i le va o vasega faafomaʻi ma meaʻai nitrous oxide pe a faʻaaogaina oloa o loʻo iai lenei kesi. Pe fa'aaogā tu'u kulimi sasa i le fale po'o le fa'atinoina o togafiti fa'afoma'i, o le malamalama i le taua o le fa'aogaina o le togi sa'o ole nitrous oxide e mafai ona fesoasoani e puipuia ai so'o se fa'alavelave fa'afuase'i ile soifua maloloina.
O ofisa fa'atonutonu e pei o le US Food and Drug Administration (FDA) ma le European Medicines Agency (EMA) o lo'o i ai se sao taua i le va'aia o le gaosiga, tufatufaina, ma le fa'aogaina o vaila'au nitrous oxide. O nei lala sooupu e faʻatulagaina tulaga faʻamaonia mo le mama, faʻailoga, ma faʻamaumauga e faʻamautinoa ai e naʻo le maualuga o le nitrous oxide e faʻaaogaina i nofoaga tau soifua maloloina.
E fa'apena fo'i, pulega o le saogalemu o mea'ai e pei o le US Food and Drug Administration (FDA) ma le European Food Safety Authority (EFSA) e fa'atonutonuina le gaosiga ma le fa'aogaina o mea'ai nitrous oxide e puipuia ai le soifua maloloina o tagata. O nei lala sooupu e fa'atuina ta'iala mo le mama, fa'ailoga, ma fa'atagaina le fa'aogaina o mea'ai nitrous oxide i mea'ai taumafa.
I le fa'ai'uga, o le fa'aeseesega i le va o foma'i nitrous oxide ma mea'ai vasega nitrous oxide e taua tele mo le malamalama i lo latou fa'aogaina ma le saogalemu. Ole nitrous oxide ile vasega faafoma'i e matua fa'amamāina ma fa'ata'ita'iina ina ia ausia tulaga maualuga mo talosaga fa'afoma'i, a'o mea'ai nitrous oxide e fa'amoemoe mo le fa'aogaina o mea'ai ma usita'ia tulafono mo le saogalemu o mea'ai. E ala i le iloaina o nei eseesega ma le tausisia o tulafono faatonutonu, tagata tomai faapitoa i le soifua maloloina, tagata tomai faapitoa i mea taumafa, ma tagata faatau e mafai ona mautinoa le saogalemu ma le talafeagai o le faaaogaina o le nitrous oxide i totonu o latou tulaga.
