Hydroponic Lettuce Yakaonekwa seYakachengeteka Kubva kuSalmonella, Kusvikira Kubuda

Salad isingaverengeki vadikani vakambundira zvigadzirwa zvehydroponic, vachivimba kuti mwana lettuce, arugula nemishonga yakasimudzwa mudzimba mumagreenhouse zvakachengeteka pane miriwo yakadzikwa kunze muvhu repurazi.

Hydroponic varimi shambadzirai zvirimwa zvavo sezvinyoro chete, zvinowanzokwidziridzwa pedyo nedzimba dzevatengi kwete muminda yepurazi iri kure. Uye nhevedzano yemakesi echepfu yechikafu akabatanidzwa kune echinyakare ivhu-akakura mashizha mashizha kubva kuCalifornia neArizona mumakore achangopfuura akawedzera kukwezva kwezvakagadzirwa hydroponic.

Asi a salmonella Kubuda kwezhizha rapfuura kwakarwarisa vanhu makumi matatu nevaviri mumatunhu mana uye yakateverwa kuBrightFarms hydroponic greenhouse muRochelle, Ill., Yakaratidza kuti kunyangwe magidhi akarimwa munzvimbo dzine denga-munzvimbo ari panjodzi yekusvibiswa.

Kunyangwe kubuda kwacho kwaive kudiki, iyo Food and Drug Administration yakaita ongororo yezvakakonzeresa, inofungidzirwa kuti ndiyo yekutanga kubvunza nezvechirwere chekudya chakabatana nemashizha emashizha ehydroponic. Iyo agency, mune ichangobva kuburitswa ripoti pane zvayakawana, yakaratidza njodzi dzinogona kuitika kubva mukutadza kuve nechokwadi chemvura yakachena mumadziva anokura uye kuchengetwa kwakakodzera kwezvinhu, uye yakakurudzira nhungamiro yekuchengetedzwa kwemapurazi ehydroponic kazhinji. Chirevo chakaoma-chinorova chakaita yekunyevera indasitiri yehydroponics uye chiratidzo kune vatengi kuti girinhi dzayo hadzina kudzivirirwa kune hutachiona.

Mukupindura denda iri, BrightFarms yakagadzira hurongwa hwekusimbisa kuchengetedzwa kwechikafu uye kunaka, sekureva kwaSteve Platt, mukuru wekambani.

FDA vaongorori - vakashanyira nzvimbo yeBrightFarms muna Chikunguru naNyamavhuvhu, panguva iyo sangano rakanga ramisa kuongorora kwaro nekuda kwezvirambidzo zveCovid-19 - haana kuwana chaicho chikonzero chekubuda. Asi kuyedza kwavo kwakawana humbowo, mudhamu remvura rekunze pedyo nenzvimbo, yesalmonella strain yakakonzera kubuda, pamwe nehumbowo hweimwe salmonella dhiza mudhamu rinokura remukati, chirevo chesangano iri chinodaro. (Salmonella utachiona, kana kuti salmonellosis, inowanzopararira kana vanhu vachidya zvokudya zvine tsvina yemhuka dzine utachiona. Utachiona hunorwisa intestinal track.)

Chirevo cheFDA chakawana matambudziko nemabatiro enzvimbo iyi yemvura yedhamu inopihwa nekanzuru, iyo inoshandiswa kana mashizha ane mashizha akarimwa mumarafu anoyangarara epolystyrene.

“Kana yangova mumadziva ari kukura, mvura yacho haigamuchirwi kuuraya utachiona kana kuti neimwe nzira,” mushumo wacho wakadaro.

Korrie Burgmeier, mutauriri weBrightFarms, mukutaura kuna Matt Lingard, mutevedzeri wemutungamiri wekambani yezvekurima nesainzi, mukuyedza kuchengetedza mvura yayo isina zvinowedzera, BrightFarms haigari ichiuraya mvura yayo. Pane kudaro, akati vashandi vanogara vachiyedza mvura nekuibata "kana bvunzo dzichiratidza njodzi."

Vakashoropodzawo nzvimbo iyi yekuchengetera zvinhu zvinokura zve hydroponic kunze kwete mushedhi, zvichisiya ichiita madonhwe eshiri uye kupindira kwemhuka. Zvinhu zvakadaro zvinoshandiswa kudzikamisa zvirimwa uye kupa chikafu chemidzi.

Chimwe chikanganiso, vaongorori vakati, ndechekuti BrightFarms haina kunyora zvakakwana "kuti kuchenesa uye kucheneswa kwemidziyo, maturusi uye zvivakwa zvinoshandiswa mukukura mabasa zvinogara zvichiitwa zvinoenderana nemaitiro ekambani."

Nyanzvi dzinoti chishumo cheFDA chinoratidza mukana wezvinetso muindasitiri yehydroponic inozivikanwa seyakadzorwa kurima nharaunda, kana CEA.

"Kutendeseka, chirevo ichi inhanho yekutanga yakanaka kune wese muECA kuti," Zvakanaka, isu tinofanirwa kuita zvakawanda, "akadaro Martin Wiedmann, nyanzvi yesalmonella uye purofesa wekuchengetedza chikafu nesainzi yechikafu paCornell University's College of. Zvekurima neHupenyu Sayenzi.

Kutanga pakati paChikunguru, BrightFarms yakatanga kurangarira saradhi magidhi munzvimbo dzinoverengeka dzeMidwestern, maererano neCDC. Yakabhadharawo kambani inobvunza nezvekuchengetedza chikafu, Matrix Sayenzi, maererano naVaPlatt, mukuru mukuru.

"Ndiyo chinangwa chedu kugadzira nzira yekurima yakachengeteka inogoneka," Mr. Platt vakadaro mune zvakanyorwa.

Kambani yakagovana nhungamiro kubva kune ese FDA neMatrix mumusangano wakavanzika nevatungamiriri veindasitiri yehydroponic, Mr. Platt vakadaro.

Kurima kweHydroponic kwakapararira kumahombekombe kusvika kumahombekombe mumakore gumi apfuura. Mamwe maoparesheni, senge BrightFarms saiti, anogara mumagreenhouses. Mamwe ari pamusoro pematenga edzimba, kana kuti akakurira muzvivako zvakaita seshongwe.

Lori Hilliard weLombard, Ill., Aive mumwe wevanhu makumi matatu nevaviri vakarwara kubva kuBrightFarms kubuda. Vaya vanorwara vaive muzera kubva mudiki pane 1 kusvika 86 makore, maererano neCenters for Disease Control and Prevention..

Akataura kuti anga ari mutsva mukugadzirwa kwehydroponic paakatenga midziyo yakati wandei yeBrightFarms saladhi girini muchitoro chemuno munaJune.

Mazuva anoverengeka gare gare, akaziva kuti chimwe chinhu chakanga chisina kururama.

"Aya ndiwo akanyanya kurwadza emuviri andati ndambonzwa," akadaro Ms. Hilliard, mubatsiri wezvekurapa paboka rakakura rekurapa. Zviratidzo zvakawedzera, uye akatanga kupisa muviri, kuoma uye manyoka akaipisisa muupenyu hwake.

Murume wake akamuendesa kune imwe kamuri yekukurumidzira, kwaakaonekwa zvisiri izvo kuti ane viral gastritis. Kumusha, manyoka akapfuurira, zvichiita kuti amhanyire kuchimbudzi kakawanda ka15 pazuva.

"Nguva dzinoverengeka, zvaiita senge basa," akadaro Ms. Hilliard. "Ndanga ndichingozhamba nekurwadziwa."

Chiremba wake akamupa makiti ekuongorora zvitsvina. Nguva pfupi yapfuura, akagamuchira runhare kubva kuDuPage County Health department, achiti aive aine chepfu yesalmonella. Paakabvunzwa kana akanga adya lettuce yeBrightFarms, zvidimbu zvepuzzle zvakabatanidzwa.

Kunyange iye zvino, akadaro, haanzwi kuporeswa zvachose. Akasvika kumatare edzimhosva neBrightFarms nemari yaasina kukwanisa kuburitsa zvichienderana nechibvumirano, sekureva kwegweta rake, William Marler.

Haawanzodya masalad zvakare, akadaro.

Pavabvunzwa nezvenyaya iyi, VaPlatt vakati: “Takarwadziwa kuziva kuti Amai Hilliard vakarwara. Uye kunyange zvazvo chikonzero chacho chakanga chisina kuwanikwa papurazi redu, mainishuwarenzi edu akakwanisa kuita chisarudzo chine tsitsi.”

CDC inofungidzira , salmonella mabhakitiriya - kubva kunzvimbo dzakawanda - anokonzera zvirwere zvinosvika mamiriyoni 1.35, 26,500 muchipatara uye 420 kufa muUnited States gore negore.

Kunyange iyo FDA isati yaburitsa chero mitemo mitsva kusvika parizvino mukupindura kubuda kwa2021, Veronika Pfaeffle, mutauriri, akati sangano iri rinoziva nezvekukura kweindasitiri yehydroponic uye yaizotora matanho anodiwa kuchengetedza hutano hwevanhu.

"CEA maitiro, akadai seaya anoshandiswa mu hydroponic greenhouse operations, anosiyana nenzira dzakakosha kubva kune maitiro anoshandiswa mukukura-mumunda, uye iyo misiyano yakasiyana-siyana inofanira kugadziriswa kubva pakuona kwekuchengetedzwa kwezvokudya," akadaro Ms. Pfaeffle.

Iyo FDA yakatora mazana matatu ezviuru zvemasampuni, mvura uye zvimwe zvinhu sechikamu chekuferefeta kwayo kweBrightFarms.

Kuwanikwa kwakakosha kwaive kuvepo kweSalmonella typhimurium - iyo dhizaini yakarwarisa vanhu makumi matatu nemumwe - mudutu-mvura bheseni pane imwe nzvimbo iri padyo nenzvimbo yeBrightFarms. Asi vaongorori vemubatanidzwa havana kukwanisa kuona kana pathogen yakasvibisa mashizha mashizha yakanga yatanga mubheseni ikapinda mugreenhouse, kana kuti yakafamba ichibva kune greenhouse ichienda kubheseni, maererano neshumo.

Vaongorori vakawanawo imwe fomu yepathogen, Salmonella Liverpool, mune dziva rekukura remukati kuBrightFarms.

"Izvi zvinoratidzira kukosha kwekudzikisa kusvibiswa kwehutachiona pamwe nekushanda nekuchengetedza madziva ekugadzira nenzira isingakonzere kupararira kwehutachiona kuchigadzirwa," chirevo chinodaro.

Vatsvagiri vepaYunivhesiti yeArkansas vakapenengura zvinyorwa zvesainzi zvakapfuura kuti vanzwisise njodzi dzinogona kuitika dzehutachiona mumiriwo yemashizha inorimwa nehydroponically. Dzidzo yavo, yakabudiswa muHorticulturae muna 2019, akagumisa kuti utachiona hwevanhu "hunongopinda mukati memiti yezvirimwa kuburikidza nekutora mishonga yakasvibiswa yezvikafu kuburikidza nemidzi."

Kristen E. Gibson, mumwe wevanyori vezvidzidzo uye purofesa wezvekuchengetedza kwezvokudya paYunivhesiti yeArkansas, anga achishanda neDhipatimendi rekurima reUnited States pakutsvakurudza kwehydroponics, achitsvaga nzira dzinogona kudzora utachiona, akadaro.

Vakuru vehurumende nevehurumende vaitsvaga vanorwara veBrightFarms vatengi vakabatsirwa kuongorora kwegenome yose, DNA fingerprint iyo inogona kubatanidza mutengi nechepfu yezvokudya kune mugadziri panzvimbo yechirwere.

“Vanogara kumba; havaendi kuna vanachiremba vavo,” VaBrackett vakadaro. "Chero kuputika kwaungazvitsvaga, kunogara kuchikosha."

Rimwe boka rinoteerera mushumo ndeye CEA Chikafu Chekuchengetedza Coalition, yakaumbwa muna 2019 nevagadziri vanotungamira, kusanganisira BrightFarms, sekureva kwemukuru wayo, Dr. Elisabeth Hagen, aimbova USDA pasi pemunyori wezvekuchengetedza chikafu.

Mubatanidzwa, une nhengo dzinenge makumi matatu, wakaburitsa zviyero zvemashizha ane mashizha muchirimo chekupedzisira, achitarisa njodzi dzine chekuita nemvura, dhizaini yekugadzira uye kushandiswa kwemishonga yezvipembenene, Dr. Hagen akadaro.

Vagadziri veECA vanogona kutsvaga chisimbiso chisimbiso kuti varatidze pamapaketi avo kana mubatanidzwa ukaona vachitevedzera zviyero zveboka.

Vamwe vakadaidzira kuti vatarisire zvimwe. Sarah Sorscher, mutevedzeri wemukuru wezvemitemo paCenter for Science muPublic Interest, boka revatengi risingabatsiri, vakati Congress inofanirwa kupa mari yakawanda kuFDA kuti ikurumidze kuongorora mapurazi ehydroponic.

Trevor Suslow, chipangamazano uye purofesa akabuda muSainzi yezvirimwa paYunivhesiti yeCalifornia, Davis, akakurudzira varimi vehydroponic kuti vatevedzere nhungamiro yesangano, iyo inosanganisira kurudziro yehutsanana hwakakodzera uye kuchengetedza mvura yakachena.

"Ibva kure, 'Yakakurira mudzimba, hapana njodzi," akadaro. "Izvi hazviratidzike kunge zvine musoro kutumira meseji."
