Kua whakatūpato te Whakahaere Hauora o te Ao i a Vietnam mō ngā tūponotanga o te whakamahi i ngā "kano ārai mate mō te kirika poaka o Awherika kāore i te tino pai."

I a Vietnam e whakarite ana ki te kaweake i ngā kano ārai mate kirika poaka o Awherika, kua whakatūpato te World Organisation for Animal Health (WOAH) me nui ake ngā whakamātautau o ngā kano ārai mate kirika poaka o Awherika. I kī te OIE kāore te kaihanga o te kano ārai, te AVAC o Vietnam, i tohatoha i ngā raraunga e ranea ana ki ngā kairangahau me ngā umanga o te ao. I tuhi anō te WHO: "Ko te whakamahinga o ngā kano ārai kore-ture me te kounga-kore, kāore pea e tiaki i te kirika poaka o Awherika, ā, kei te tūpono te hora i te huaketo kano ārai, ka puta ai he mate kino, he mate mau tonu rānei."Maimoatanga kore kinohe mea tino nui.
