Ingabe inyama etshalwe elebhu iwukudla kwekusasa?

I-penicillin, imithi yokugoma kanye nezitho zomzimba womuntu konke kwakhiwa elabhorethri, futhi manje, ngisho nenyama ekhuliswe elebhu isiba utshalomali oludumile lwesayensi. I-Google ixhase ithimba lonjiniyela ngo-Agasti 5 2013 ukuze lidale i-hamburger patty yokuqala ekhule elebhu. Ngemva kokuhlanganisa amangqamuzana emisipha amancane angu-20,000 endaweni in-vitro imvelo ngenkathi kusetshenziswa u-$375 000, umkhiqizo wokuqala wenyama otshalwe elebhu wadalwa.

UWillem Van Eelen, omunye wabacwaningi abaphezulu benyama etshalwe elebhu, wenze inhlolokhono ngo-2011 neNew Yorker, echaza ukuthi le nqubo isebenza kanjani. U-Eelen uthi, “Inyama ye-in-vitro… ingenziwa ngokufaka amangqamuzana ambalwa engxubeni yezakhi eziwasiza ande.” Uqhubeka echaza ukuthi “njengoba amangqamuzana eqala ukukhula ndawonye, ​​akhe izicubu zemisipha… izicubu zinganwetshwa futhi zibunjwe zibe ukudla, okungase, ngokombono, kudayiswe, kuphekwe futhi kudliwe njenganoma iyiphi i-hamburger yenyama egayiwe… noma amasoseji.”

Ngomzamo owanele, isayensi inganikeza abantu inyama esiyifisayo ngaphandle kwemiphumela elimazayo emvelweni kanye nokuhlukunyezwa kwamapulazi ezinkomo. Ngeshwa, inyama ekhuliswe ilebhu ayizange idonse ukunaka okukhulu kuze kube sekufeni kuka-Eelen.

Nakuba inyama ekhuliswe elebhu inikeza ithemba ngomthombo wokudla ongayicekeli phansi indawo ezungezile, akubona bonke abasekela inyama etshalwe elebhu. U-Corry Curtis, isazi sokudla esishisekayo, nezinye izazi zemvelo ezinomqondo ofanayo banomuzwa wokuthi ukudla kuyasuka emvelweni. “Ngiyabona ukuthi inyama ekhuliswe elebhu ingenza okuningi okuhle emazweni asemhlabeni wesithathu futhi izuzise kakhulu imvelo, kodwa akuyona imvelo,” kusho uCurtis. UCurtis uphinde waveza ukuthi nakuba ukudla okushintshwe izakhi kunikeza izinzuzo eziningi, abantu bathembela ezimpahleni ezithuthukisiwe ngamakhemikhali.

UCurtis ugcizelela ukuthi inyama ekhuliswe ilebhu ingeyona eyemvelo kangangokuthi inyama icishe isuswe emvelweni uqobo. Uphinde wachaza ukuthi uma lo mkhuba uqala, inyama ingase idliwe ngezinga eliyingozi. “Ucwaningo oluhamba phambili luye lwafakazela ukuthi inyama, enamaprotheni amaningi, ingenye yezimbangela ezihamba phambili zesifo sikashukela hhayi ushukela,” kuchaza uCurtis.

Mhlawumbe ososayensi bazohlanganisa zombili izimfundiso zikaCurtis kanye no-Eelen ukuze basinikeze i-hamburger engcono kakhulu lapho inyama ekhuliswe elebhu isitholakala kabanzi.
