He pai te mahi a ngā whakaritenga waikawa ki te whakapai ake i te nakunaku me te tere o te whāngai a ngā kararehe wai, ki te pupuri i te whanaketanga hauora o te ara kai me te whakaiti i te putanga mai o ngā mate. Ina koa i ngā tau tata nei, kua tino whanake haere te mahi ahuwhenua ika i runga i te tauine nui me te kaha, ā, kua āta hiahiatia kia whakaitihia, kia āraihia rānei te whakamahinga o ngā paturopi me ētahi atu rongoā, ā, kua piki haere te kitea o ngā painga o ngā whakaritenga waikawa.
Nā, he aha ngā painga motuhake o te whakamahinga o ngā waikawa ki ngā Whāngai Wai?

1. Ka taea e ngā whakaritenga waikawa te whakaiti i te waikawa o te whāngai. He rerekē te kaha here waikawa mō ngā momo kai rerekē, ko ngā rauemi kohuke te mea teitei rawa, ko ngā rauemi kararehe te mea tuarua, ā, ko ngā rauemi tipu te mea iti rawa. Mā te tāpiri waikawa ki te kai ka taea te whakaiti i te pH me te taurite electrolyte o te kai. Te tāpiri waikawa pērā i tepāhare pākawa diformateka taea e te kai te whakapai ake i tōna kaha ārai mate, te ārai i te pirau me te harore o te kai, me te whakaroa i tōna oranga papa.

2. Ngā waikawa rauropihe mahi patu huakita, ā, ka ārai i te tipu o ngā moroiti, nā reira ka whakaitihia te mimiti o ngā moroiti mate pea me ō rātou matū paitini e ngā kararehe, ko te waikawa propionic te mea tino kaha ki te patu i ngā mate pāwera, ā, ko te waikawa formic te mea tino kaha ki te patu huakita. Ko te paraoa ika he momo kai wai kāore e taea te whakakapi katoa tae noa ki tēnei wā. I kitea e Malicki me ētahi atu ko te ranunga o te waikawa formic me te waikawa propionic (1% horopeta) ka taea te aukati i te tipu o te E. coli i roto i te paraoa ika.

3. Te whakarato pūngao. He nui te pūngao kei roto i te nuinga o ngā waikawa waro. Ka taea e ngā ngota waikawa mekameka poto me te taumaha ngota iti te tomo ki te epithelium whekau mā te horapa kore mahi. E ai ki ngā tātaitanga, ko te pūngao o te waikawa propionic he 1-5 ngā wā i te pūngao o te witi. Nō reira, me tatau te pūngao kei roto i ngā waikawa waro ki te pūngao katoa okai kararehe.
4. Whakatairanga i te kai.I kitea mā te tāpiri i ngā waikawa ki te kai ika ka puta te reka kawa, ka whakaoho i ngā puku reka o te ika, ka hiahia ai rātou, ā, ka tere ake ai tā rātou kai.
