Listerioza
Zapobieganie i profilaktyka

Listerioza, wywoływana przez Listeria monocytogenes, jest rzadką, ale potencjalnie ciężką infekcją, szczególnie niebezpieczną dla kobiet w ciąży (ryzyko zakażenia wzrasta około 10-krotnie, a u kobiet hiszpańskiego pochodzenia nawet 24-krotnie), noworodków, osób powyżej 65 roku życia oraz pacjentów z immunosupresją lub chorobami przewlekłymi. Bakterie te są szeroko rozpowszechnione w środowisku i mogą namnażać się w temperaturach chłodniczych (poniżej 4°C), co utrudnia ich eliminację. Profilaktyka opiera się na przestrzeganiu zasad bezpiecznego przygotowywania i przechowywania żywności, w tym gotowaniu do temperatury minimum 74°C, unikaniu surowych i niepasteryzowanych produktów mlecznych, miękkich serów, wędlin i innych produktów wysokiego ryzyka. Szczególną uwagę należy zwrócić na higienę kuchni, zapobieganie zanieczyszczeniu krzyżowemu oraz szybkie schładzanie i odpowiednie przechowywanie żywności.

Listerioza – wprowadzenie do profilaktyki

Listerioza to rzadka, lecz potencjalnie poważna infekcja wywoływana przez bakterię Listeria monocytogenes. Szacuje się, że rocznie ok. 1600 osób w Stanach Zjednoczonych zapada na tę chorobę. Mimo rzadkiego występowania, konsekwencje zakażenia mogą być poważne, zwłaszcza dla określonych grup wysokiego ryzyka1. Bakterie Listeria są szeroko rozpowszechnione w środowisku naturalnym, występują w glebie, wodzie, ściekach, gniących roślinach oraz u zwierząt2. Mogą przetrwać i namnażać się nawet w niskich temperaturach lodówki, co czyni je szczególnie niebezpiecznymi3.

Listerioza jest szczególnie niebezpieczna dla kobiet w ciąży, które są około 10 razy bardziej narażone na zakażenie Listerią niż ogólna populacja. Ryzyko to wzrasta do około 24 razy w przypadku kobiet ciężarnych pochodzenia hiszpańskiego4. Zakażenie Listerią może być śmiertelne, zwłaszcza u noworodków, osób powyżej 65 roku życia oraz osób z osłabionym układem odpornościowym lub przewlekłymi chorobami5.

Grupy wysokiego ryzyka

Szczególnie narażone na powikłania listeriozy są następujące grupy67:

Profilaktyka listeriozy – bezpieczeństwo żywności

Główną drogą zapobiegania listerioza jest przestrzeganie zasad bezpiecznego przygotowywania i przechowywania żywności. Poniżej przedstawiono najważniejsze zalecenia dotyczące profilaktyki89:

Bezpieczne gotowanie i przygotowywanie posiłków

  • Dokładne gotowanie surowych produktów pochodzenia zwierzęcego (wołowina, wieprzowina, drób, ryby). Używaj termometru spożywczego, aby upewnić się, że mięso, drób i potrawy z jajek są ugotowane do bezpiecznej temperatury (minimum 74°C)10
  • Nie płucz surowego mięsa ani drobiu – pomaga to zapobiec rozprzestrzenianiu się bakterii na inne powierzchnie w kuchni11
  • Dokładnie myj warzywa i owoce pod bieżącą wodą, szczególnie przed jedzeniem ich na surowo12
  • Używaj szczoteczki do czyszczenia warzyw i owoców pod czystą, bieżącą wodą13
  • Oddzielaj surowe mięso od warzyw oraz od gotowanych pokarmów i żywności gotowej do spożycia14
  • Odgrzewaj produkty gotowe do spożycia, takie jak hot dogi, aż będą gorące i parujące15

Prawidłowe przechowywanie żywności

  • Utrzymuj odpowiednią temperaturę lodówki – poniżej 4°C, a zamrażarki poniżej -18°C16
  • Szybko schładzaj żywność – pomaga to zapobiec psuciu się produktów łatwo psujących się. Im dłużej żywność jest przechowywana w lodówce, tym większa szansa na namnażanie się Listerii17
  • Regularnie czyść lodówkę i natychmiast wycieraj rozlane płyny18
  • Spożywaj produkty gotowe do spożycia jak najszybciej po zakupie19
  • Sprawdzaj daty przydatności do spożycia przed jedzeniem20
  • Przechowuj surowe mięso oddzielnie od warzyw, owoców i potraw gotowych do spożycia21

Higiena kuchni

  • Myj ręce, noże i deski do krojenia po obróbce surowej żywności22
  • Myj ręce ciepłą wodą z mydłem przez co najmniej 20 sekund przed i po przygotowywaniu jedzenia23
  • Regularnie czyść i dezynfekuj powierzchnie kuchenne – to najlepszy sposób na uniknięcie skażenia żywności Listerią24
  • Unikaj zanieczyszczenia krzyżowego – płyn z opakowań hot dogów trzymaj z dala od innych pokarmów, naczyń i powierzchni, na których przygotowywane jest jedzenie25

Żywność wysokiego ryzyka

Osoby z grup wysokiego ryzyka powinny unikać następujących produktów spożywczych, które są szczególnie narażone na skażenie bakteriami Listeria2627:

Produkty mleczne

  • Niepasteryzowane (surowe) mleko i produkty z niego wykonane – należy używać wyłącznie pasteryzowanego mleka i produktów mlecznych28
  • Miękkie sery, takie jak feta, brie, camembert, sery z niebieską pleśnią oraz sery w stylu meksykańskim (queso blanco, queso fresco) – chyba że na etykiecie wyraźnie zaznaczono, że zostały wyprodukowane z pasteryzowanego mleka29
  • Lody z automatów (soft serve ice-cream)30

Produkty mięsne

  • Wędliny i mięsa delikatesowe, chyba że zostały podgrzane do temperatury parowania (minimum 74°C)31
  • Hot dogi, chyba że zostały podgrzane do temperatury parowania32
  • Schłodzone pasty mięsne i pasztety sprzedawane w delikatesach lub z lodówki sklepowej – bezpieczne są pasty konserwowe lub o długim terminie przydatności do spożycia33

Inne produkty wysokiego ryzyka

  • Schłodzone wędzone owoce morza, takie jak łosoś wędzony, o ile nie są zawarte w gotowanym daniu, np. zapiekance34
  • Surowe kiełki – należy je dokładnie gotować przed spożyciem35
  • Pokrojone melony – należy je spożyć od razu lub przechowywać w lodówce w temperaturze poniżej 4°C i zużyć w ciągu 7 dni36
  • Surowe grzyby – osoby z grupy podwyższonego ryzyka powinny unikać surowych grzybów i spożywać je tylko po dokładnym ugotowaniu37
  • Gotowe do spożycia sałatki z barów sałatkowych, barów kanapkowych i delikatesów38

Wytyczne dla profesjonalistów i przemysłu spożywczego

Kontrola L. monocytogenes jest wymagana na wszystkich etapach łańcucha żywnościowego. Konieczne jest zintegrowane podejście, aby zapobiec namnażaniu się bakterii w gotowym produkcie spożywczym3940:

  • Wdrożenie Dobrych Praktyk Higienicznych (GHP) i Dobrych Praktyk Produkcyjnych (GMP)41
  • Stosowanie systemu zarządzania bezpieczeństwem żywności opartego na zasadach Analizy Zagrożeń i Krytycznych Punktów Kontroli (HACCP)42
  • Testowanie produktów pod kątem kryteriów mikrobiologicznych podczas walidacji i weryfikacji prawidłowego funkcjonowania procedur HACCP43
  • Monitoring środowiskowy w celu identyfikacji i eliminacji środowisk sprzyjających rozwojowi L. monocytogenes44
  • Pasteuryzacja i gotowanie – L. monocytogenes w żywności jest zabijana przez pasteuryzację i gotowanie45

Wyzwania związane z kontrolą L. monocytogenes są znaczące ze względu na wszechobecny charakter bakterii, wysoką odporność na powszechnie stosowane metody konserwacji (sól, wędzenie, kwaśne środowisko) oraz zdolność do przetrwania i namnażania się w temperaturach chłodniczych (około 5°C)46.

Zaawansowane metody prewencji

  • Bakteriofagi – FDA zatwierdziła różne dodatki do żywności, w tym spray z bakteriofagami (Listeria Phage P100), który może eliminować L. monocytogenes. Spray ten jest wykorzystywany głównie do wędlin i serów47
  • Probiotyki – badania wykazały, że niektóre szczepy bakterii probiotycznych, np. Lactobacillus, są wysoce skuteczne w hamowaniu rozwoju Listerii48
  • Sekwencjonowanie całego genomu (WGS) – zaawansowana technologia pomagająca śledzić i zapobiegać wybuchom epidemii49

Szczególne zalecenia dla kobiet w ciąży

Kobiety w ciąży powinny zachować szczególną ostrożność ze względu na zwiększone ryzyko listerozy oraz potencjalnie poważne konsekwencje dla płodu5051:

  • Unikać surowego mleka i niepasteryzowanych produktów mlecznych52
  • Unikać miękkich serów, chyba że są wyraźnie oznaczone jako wykonane z pasteryzowanego mleka53
  • Podgrzewać wędliny i hot dogi do temperatury parowania przed spożyciem54
  • Unikać schłodzonych past mięsnych i pasztetów z delikatesów55
  • Unikać schłodzonych wędzonych owoców morza, chyba że są zawarte w gotowanym daniu56
  • Unikać kontaktu z dzikimi i domowymi zwierzętami57
  • Dokładnie myć owoce i warzywa przed spożyciem58

W przypadku zakażenia listeriozą podczas ciąży, szybkie leczenie antybiotykami może często zapobiec zakażeniu płodu lub noworodka59. Jeśli kobieta w ciąży spożyła żywność, która została wycofana z powodu skażenia Listerią, powinna być świadoma objawów zakażenia i natychmiast skontaktować się z lekarzem w przypadku ich wystąpienia60.

Profilaktyka w kuchniach instytucjonalnych

W placówkach opieki zdrowotnej i innych instytucjach zalecane są następujące działania profilaktyczne6162:

  • Wdrożenie szczegółowych procedur czyszczenia i dezynfekcji – utrzymanie wysokich standardów higieny kuchni wymaga wytycznych i świadomości dotyczącej Listerii i bakterii ogólnie63
  • Stosowanie wytycznych kontroli zakażeń (IPC) zgodnie z zaleceniami WHO w celu zapobiegania rozprzestrzenianiu się zakażeń związanych z opieką zdrowotną (HAI)64
  • Opracowanie planu reagowania w przypadku wystąpienia ogniska zakażenia, aby wszyscy członkowie zespołu wiedzieli, co robić w przypadku zgłoszeń listeriozy65
  • Regularny audyt lub testowanie bakteriologiczne przez strony trzecie jako proaktywne narzędzie do zapobiegania listerioza66

Postępowanie po ekspozycji na Listerię

Jeśli podejrzewasz, że mogłeś być narażony na Listerię, powinieneś6768:

  • Sprawdzić informacje o wycofanych produktach i nie spożywać ich69
  • Skontaktować się z lekarzem, jeśli wystąpią jakiekolwiek objawy, zwłaszcza jeśli należysz do grupy wysokiego ryzyka70
  • Poinformować lekarza o spożyciu żywności, która została wycofana z powodu skażenia Listerią71
  • Odpowiedzieć na wezwanie z lokalnego lub stanowego departamentu zdrowia, aby inne osoby w twoim domu lub w pobliżu nie były zagrożone listeriozą72

W przypadku zakażenia listeriozą, szybkie leczenie antybiotykami może często zapobiec poważnym powikłaniom, szczególnie u kobiet w ciąży73.

Działania w zakresie zdrowia publicznego

Agencje zdrowia publicznego odgrywają ważną rolę w zapobieganiu listerioza poprzez7475:

  • Dostarczanie wytycznych dla przemysłu76
  • Opracowywanie i egzekwowanie przepisów77
  • Monitorowanie potencjalnych źródeł zanieczyszczenia78
  • Edukację konsumentów, zwłaszcza tych z grup wysokiego ryzyka, i szkolenie osób zajmujących się żywnością w zakresie bezpiecznego obchodzenia się z żywnością79
  • Śledzenie i badanie przypadków listeriozy w celu identyfikacji i zapobiegania dalszym infekcjom80

W Stanach Zjednoczonych wysiłki są skierowane na zapobieganie listerioza, w tym zmniejszenie zanieczyszczenia Listerią żywności gotowej do spożycia, takiej jak przetworzone mięsa, właściwe przygotowanie i przechowywanie żywności oraz ogólne bezpieczeństwo żywności, higienę i sanitację81.

Podsumowanie

Listerioza jest rzadką, ale potencjalnie poważną chorobą, która może być w dużej mierze zapobiegana poprzez przestrzeganie zasad bezpieczeństwa żywności i unikanie produktów wysokiego ryzyka, zwłaszcza przez osoby z grup podwyższonego ryzyka. Kluczowe zasady profilaktyki obejmują: właściwe gotowanie i przygotowywanie żywności, odpowiednie przechowywanie produktów spożywczych, utrzymywanie higieny kuchni oraz unikanie żywności wysokiego ryzyka przez osoby narażone8283.

Szczególnie ważne jest, aby kobiety w ciąży, osoby starsze i osoby z osłabionym układem odpornościowym były świadome ryzyka związanego z listeriozą i podejmowały dodatkowe środki ostrożności w celu ochrony swojego zdrowia84. W przypadku wystąpienia objawów listeriozy, szybka interwencja medyczna może pomóc zapobiec poważnym powikłaniom85.

    https://americanpregnancy.org/healthy-pregnancy/pregnancy-concerns/listeria-during-pregnancy/
    During pregnancy, it is important to be aware of what you put inside your body. You should be aware of what is good to eat and also what is not so good to eat because some foods may cause you to contract listeria during pregnancy. Listeria is a type of bacteria that can be found in some contaminated foods. Listeria can cause problems for both you and your baby. Although listeriosis (the illness from ingesting Listeria) is rare, pregnant women are more susceptible to it than non-pregnant healthy adults. […] Following these guidelines can greatly reduce your chances of contracting listeria in pregnancy: Eat hard cheeses instead of soft cheeses: The CDC has recommended that pregnant women avoid soft cheeses such as feta, Brie, Camembert, blue-veined cheeses and Mexican style cheeses such as queso fresco, queso blanco, and panela that do not state they are pasteurized. Hard cheeses such as cheddar and semi-soft cheeses such as mozzarella are safe to consume. Pasteurized processed cheese slices and spreads such as cream cheese and cottage cheese can also be safely consumed. The most important thing to do is to read the labels!

    Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. The Centers for Disease Control and Prevention (CDC) estimates that about one in seven (14%) cases of Listeria infection occurs during pregnancy and can cause fetal loss (miscarriage or stillbirth), preterm labor, and illness or death in newborn infants. […] If you are pregnant, the CDC offers these specific recommendations to reduce your risk of contracting this infection and passing it onto your baby. Do not eat hot dogs, luncheon meats, cold cuts, other deli meats or fermented or dry sausages unless they are heated to an internal temperature of 165F or until steaming hot just before serving. Avoid getting fluid from hot dog and lunch meat packages on other foods, utensils, and food preparation surfaces, and wash hands after handling hot dogs, luncheon meats, and deli meats. Pay attention to labels. Do not eat refrigerated pt or meat spreads from a deli or meat counter or from the refrigerated section of a store. Foods that do not need refrigeration, like canned or shelf-stable pt and meat spreads, are safe to eat. Refrigerate after opening. Do not eat soft cheese such as feta, queso blanco, queso fresco, brie, Camembert, blue-veined, or panela (queso panela) unless it is labeled as made with pasteurized milk. Make sure the label says, MADE WITH PASTEURIZED MILK. Be aware that Mexican-style cheeses made from pasteurized milk, such as queso fresco, likely contaminated during cheese-making, have caused Listeria infections. Do not eat refrigerated smoked seafood, unless it is contained in a cooked dish, such as a casserole, or unless it is a canned or shelf-stable product. (Refrigerated smoked seafood, such as salmon, trout, whitefish, cod, tuna, and mackerel, is most often labeled as nova-style, lox, kippered, smoked, or jerky.) Canned and shelf stable tuna, salmon, and other fish products are safe to eat. […] Because of the significant impact Listeriosis can have on you and your baby, proper precautions and prevention are very important. If you experience any of the above symptoms, see your doctor or healthcare provider immediately.
