Inqaku loMhleli: Le kholamu yoluvo yahlukile kuluvo oluthiwe thaca ngumbhali wemihlathi yeendwendwe uBrian Ronholm “Njani Yokunqanda ukubhideka ngesantya sokuxhela iinkukhu”.
Ukuxhelwa kweenkukhu akuhambelani neemfuno ze-HACCP 101. Iingozi eziphambili zeenkukhu eziluhlaza yiSalmonella kunye neCampylobacter pathogens. Ezi ngozi azizange zibonwe ngexesha lokujongwa kweentaka ezibonakalayo ze-FSIS. Izifo ezibonakalayo ezinokubonwa ngabahloli be-FSIS zisekelwe kwi-paradigm ye-19 kunye ne-20 yenkulungwane yokuba izifo ezibonakalayo zibeka ingozi kwimpilo yoluntu. Iminyaka engamashumi amane yedatha yeCDC iyakuphikisa oku.
Ngokubhekiselele kungcoliseko lwe-fecal, kwiikhikhini zabathengi azikho iinkukhu ezingaphekwanga, kodwa zingcoliseka. Nantsi inkcazo: Luber, Petra. Ngowama-2009. Iinkuku okanye Amaqanda Angavuthwanga Ngokuchaseneyo Neenkukhu okanye Amaqanda—Ziziphi Iingozi Ekufuneka Zipheliswe Kuqala? amazwe ngamazwe. J. I-microbiology yokutya. 134:21-28 . La mazwana axhaswa ngamanye amanqaku abonisa ukungakwazi kwabathengi abaqhelekileyo.
Ukongezelela, uninzi lwezingcolisi ze-fecal azibonakali. Xa i-epilator isusa iintsiba, iminwe icinezela isidumbu, ikhupha i-feces kwi-cloaca. Iminwe ke icinezele ilindle elithile kwiintsiba ezingenanto, ezingabonakaliyo kumhloli.
Iphepha leNkonzo yoPhando lwezoLimo (ARS) elixhasa ukuhlanjwa kweelindle ezibonakalayo kwizidumbu zenkukhu liye labonisa ukuba ilindle elingabonakaliyo lingcolisa izidumbu (Blankenship, LC et al. 1993. Broiler Carcasses Reprocessing, Extra Evaluation. J. Food Prot. 56: 983) . -985.).
Ekuqaleni koo-1990, ndaphakamisa iprojekthi yophando ye-ARS kusetyenziswa izikhombisi zemichiza ezifana ne-faecal stanols ukufumanisa ungcoliseko olungabonakaliyo lwelindle kwinyama yenkomo. IiCoprostanols zisetyenziswa njengee-biomarkers kwilindle labantu kwindawo esingqongileyo. Isazi ngebhayoloji ye-ARS yaqaphela ukuba uvavanyo lunokuphazamisa ishishini lenkukhu.
Ndaphendula ndathi ewe, ngoko ndagxila kwinyama yenkomo. UJim Kemp kamva wavelisa indlela yokukhangela ingca yemetabolites kwilindle lenkomo.
Eli lindle lingabonakaliyo kunye neebhaktheriya zeso sizathu le nto i-ARS kunye nabanye bebonisa iminyaka engaphezu kwamashumi amathathu ukuba iintsholongwane ezingena kwiindawo zokuxhela zifumaneka ekutyeni. Nali inqaku lakutshanje: Berghaus, Roy D. et al. Inani leSalmonella kunye neCampylobacter ngo-2013. isicelo. ULwesithathu. Microl., 79: 4106-4114.
Iingxaki zePathogen ziqala efama, efama, nakwindawo yokuqandusela. Ukulungisa oku, ndingacebisa ukuba isantya somgca kunye nemiba yokubonakala iyisibini. Nali inqaku “elidala” kulawulo lokuvuna kwangaphambili: Pomeroy BS et al. Ngo-1989 Uphononongo olunokwenzeka lokuveliswa kweeturkeys ezingena-salmonella. Intaka diss. 33:1-7 . Maninzi amanye amaphepha.
Ingxaki ekuphumezeni ulawulo lokuvuna kwangaphambili inxulumene neendleko. Uyenza njani inkuthazo yemali yokulawula?
Ndiya kuncoma iindawo zokuxhela ukunyusa isantya somgca, kodwa kuphela loo mithombo engenazo iingozi ezinkulu, i-Salmonella kunye neCampylobacter, okanye ubuncinane ayinayo i-clinical strains (Kentucky Salmonella, enokuba yi-probiotic ukuba ayinayo i-virulence genes. ). Oku kuya kubonelela ngenkuthazo yezoqoqosho ukuphumeza amanyathelo okulawula kunye nokunciphisa umthwalo wezempilo yoluntu onxulumene nokuveliswa kweenkukhu (amaphepha amaninzi ajongana nalo mba wongezelelweyo.
