Nkhani

Ndemanga ya mkonzi: Malingaliro awa akusiyana ndi malingaliro operekedwa ndi wolemba nkhani mlendo Brian Ronholm mu "Momwe Mungapewere Kusokonezeka ndi Kuthamanga kwa Nkhuku Zopha Nkhuku".
Kupha nkhuku sikutsata zofunikira za HACCP 101. Zowopsa zazikulu za nkhuku zosaphika ndi Salmonella ndi Campylobacter pathogens. Zowopsa izi sizinadziwike panthawi yomwe FSIS imayang'ana mbalame. Matenda owoneka omwe owunika a FSIS amatha kuwona amachokera ku 19th ndi 20th century paradigm kuti matenda owoneka amakhala pachiwopsezo ku thanzi la anthu. Zaka makumi anayi za data za CDC zimatsutsa izi.
Ponena za kuipitsidwa kwa ndowe, m'makhitchini ogula si nkhuku zosapsa, koma zowonongeka. Nayi mwachidule: Luber, Petra. 2009. Nkhuku Kapena Mazira Osaphimbidwa Mosiyana-siyana—Kodi Ndi Mavuto Ati Oti Athetse? mayiko. J. Food Microbiology. 134:21-28 . Ndemangayi ikuthandizidwa ndi nkhani zina zomwe zimasonyeza kusakhoza kwa ogula wamba.
Kuonjezera apo, zowonongeka zambiri za ndowe siziwoneka. Pamene epilator imachotsa nthenga, zala zimafinya nyama, zimatulutsa ndowe kuchokera ku cloaca. Kenako zalazo zimakanikizira ndowe zina mu nthenga zopanda kanthu, zosaoneka kwa woyendera.
Pepala la Agricultural Research Service (ARS) lothandizira kutsuka kwa ndowe zooneka kuchokera ku mitembo ya nkhuku lasonyeza kuti ndowe zosaoneka zimawononga mitembo (Blankenship, LC et al. 1993. Broiler Carcassses Reprocessing, Addiction Evaluation. J. Food Prot. 56: 983) . -985.)
Kumayambiriro kwa zaka za m’ma 1990, ndinapereka lingaliro la ntchito yofufuza ya ARS pogwiritsa ntchito zizindikiro za mankhwala monga ma stanols a ndowe kuti azindikire kuipitsidwa ndi ndowe zosaoneka pa mitembo ya ng’ombe. Coprostanols amagwiritsidwa ntchito ngati biomarkers mu ndowe za anthu m'chilengedwe. Katswiri wa sayansi ya zamoyo za ARS adanenanso kuti kuyezetsa kumatha kusokoneza malonda a nkhuku.
Ndinayankha kuti inde, choncho ndinaika mtima wanga pa nyama ya ng’ombe. Jim Kemp pambuyo pake adapanga njira yodziwira ma metabolites a udzu mu ndowe za ng'ombe.
Ndowe zosaoneka ndi mabakiteriya ndi chifukwa chake ARS ndi ena akhala akunena kwa zaka zoposa makumi atatu kuti tizilombo toyambitsa matenda timalowa m'malo ophera nyama timapezeka pa chakudya. Nayi nkhani yaposachedwa: Berghaus, Roy D. et al. Chiwerengero cha Salmonella ndi Campylobacter mu 2013. Zitsanzo za minda ya organic ndi kutsuka kwa mitembo ya broiler ya mafakitale pakupanga zomera. ntchito. Lachitatu. Microl., 79: 4106-4114.
Mavuto a tizilombo toyambitsa matenda amayambira pafamu, pafamu, ndi m’malo opulumukirako. Kuti ndikonze izi, ndinganene kuti liwiro la mzere ndi zovuta zowonekera ndizochiwiri. Nayi nkhani "yakale" yokhudzana ndi kukolola kusanachitike: Pomeroy BS et al. 1989 Kafukufuku wotheka kupanga ma turkeys opanda salmonella. Mbalame diss. 33:1-7 . Palinso mapepala ena ambiri.
Vuto lokhazikitsa dongosolo lokonzekera kukolola kusanachitike ndi lokhudzana ndi ndalama. Kodi mungapangire bwanji zolimbikitsa zachuma kuti muziwongolera?
Ndikupangira malo ophera nyama kuti awonjezere liwiro la mzere, koma okhawo omwe alibe zoopsa zazikulu, Salmonella ndi Campylobacter, kapena alibe zovuta zachipatala (Kentucky Salmonella, yomwe ingakhale probiotic ngati ilibe majini a virulence. ). Izi zitha kupereka chilimbikitso pazachuma kukhazikitsa njira zowongolera ndikuchepetsa mtolo waumoyo wa anthu okhudzana ndi kupanga nkhuku (mapepala ambiri amayankha nkhaniyi.
