Ucwaningo olwenziwe ososayensi baseSingapore luqinisekisile ukuthi ukusetshenziswa ngokweqile kwenyama ebomvu ne-avian emhlophe kungaholela engcupheni yokwanda kwesifo sikashukela. Muva nje, iningi labaphenyi belinaka ukudla okuhambisana nokudla imifino, kufakazela ukuthi baphilile kakhulu. Ngasikhathi sinye, ososayensi abaningi bahlobanisa ukusetshenziswa kwenyama nengozi eyandayo yokuthuthuka kwesifo sikashukela.
Ababhali bocwaningo olusha baqinisekisile okutholwe ngaphambilini. Ngaphezu kwalokho, kufakwe imibono emisha yokuthi kungani abathandi benyama bengaphenduka abanikazi besifo sikashukela.
USolwazi Wun-Pui Koch wafunda ubudlelwane phakathi kokufakwa kwenqwaba yenyama ebomvu ekudleni okujwayelekile, kanye nenkukhu, inhlanzi kanye ne-shellfish enesifo sikashukela sohlobo 2.

Kwatholakala ukuthi ngokudla kakhulu i-iron, kunobungozi obukhulayo bokukhula kwesifo sikashukela. Abaphenyi babe sebebheka ukuthi ukusetshenziswa kwe-iron kungayithinta kanjani ingozi yomuntu ngamunye.
Ngemuva kokulungiswa okunye, ubudlelwane phakathi kwenani lenyama ebomvu ekhona ekudleni nengozi yesifo sikashukela kwahlala kubalulekile kusukela ekubukweni kwezibalo, kepha ubudlelwane nokusetshenziswa kwenkukhu abusatholakali. Kodwa-ke, ososayensi bayabona ukuthi lokhu kungenzeka kakhulu ngenxa yokuthi kwezinye izingxenye zenkukhu incane i-iron ikhona, futhi ngenxa yalokho, ubungozi buncishisiwe.
