J'ai une question de voyageur anxieux à destination de connaisseurs de la Bolivie.
Lors d'un séjour en Bolivie il y a un peu plus de 2 ans, j'ai mangé de la charcuterie (un genre de jambon de pays) achétée dans une épicerie de Samaipata, sous cellophane il me semble.
Or depuis j'ai lu qu'en Bolivie la viande de porc pouvait véhiculer un certain nombre de maladies lorsqu'elle n'était pas cuite (tenia, trichinose, ...), ce qui est le cas pour la charcuterie (la fumaison ne tue pas les parasites).
Par conséquent, je m'inquiète un peu (surtout pour le tenia du porc (tenia solium)). C'est pour cela que je fais appelle à vos grandes connaissances de la Bolivie.
Du coup, j'aimerais avoir des réponses aux questions suivantes :
- Y a-t-il un risque d’attraper des maladies en mangeant de la charcuterie en Bolivie ?
- Lorsqu’on déconseille de manger de la viande de porc non cuite en Bolivie, de quoi parle-t-on exactement ? Uniquement la viande de porc achetée sur un petit étal de marchand (car celle-ci ne serait pas contrôlée et serait potentiellement vectrice de maladies) ? De tous les types de viande de porc confondus, y compris de la charcuterie achetée sous cellophane dans une épicerie ?
- La charcuterie qui est commercialisée est-elle soumise à plus de contrôles sanitaires que la viande de porc « normale » (dans la mesure où elle est forcément mangée crue) ?
En résumé, dois-je m’inquiéter d’avoir attrapé des maladies (ténia du porc notamment) en mangeant de la charcuterie achetée dans une petite épicerie en Bolivie ?
Merci beaucoup d’avance pour vos réponses et pour le temps que vous y consacrerez !
Je déterre ça deux ans après car j'ai appris qu'on pouvait être porteur du tenia du porc sans avoir de symptômes apparents. Concernant la trichinose, je crois que je l'aurais senti passé assez rapidement.
D'où mes questions sur le risque d'avoir attrapé le tenia en mangeant de la charcuterie en Bolivie...
Je me suis déjà renseigné et aucun examen ne permet d'écarter à 100 % la présence d'un tenia du porc (c'est une sale bête qui sait bien se cacher !).
C'est pour cela que j'aurais aimé avoir l'avis de quelqu'un qui connait bien la Bolivie (y ayant vécu ou s'y rendant souvent) sur les risques éventuels liés à la consommations de charcuterie.
Je souhaiterais au moins savoir s'il est fréquent pour les voyageurs de consommer de la charcuterie ou si je suis le seul à m'y être aventuré...
Mmmm... Je connais plusieurs personnes qui ont eu un tenia, et ils s'en sont tous aperçu assez rapidement.
Je crois que tu t'inquiètes démesurément.
Je n'ai pas dans l'idée que TOUS les porcs boliviens soient infectés (d'ailleurs je pense que j'ai mangé aussi de la charcuterie lors de mon séjour en Bolivie il y a 10 ans).
Si deux ans après, tu n'as pas le moindre symptôme, c'est probablement que tu ne l'as pas attrapé.
pour te rassurer (ou pas), les cas de contamination par les vers parasitaires "taenia" ou ténia présentent des symptômes rapidement (enfin dans les 3 mois, age de reproduction du parasite).
"Régulièrement, des anneaux contenant les œufs se libèrent et sont expulsés par l’anus. Les anneaux du ver solitaire sont de forme plate, rectangulaire et peuvent mesurer jusqu'à 2 cm de long sur 6 à 8 mm de large. Ils sont souvent décrits comme ressemblant à des pâtes alimentaires.
La découverte de ces anneaux dans les sous-vêtements, les selles, les draps, ou sous la douche est souvent le premier signe de la présence du ténia dans l’organisme. Les anneaux s’expulsent souvent de manière active car ils sont mobiles, c’est pourquoi ils peuvent être retrouvés en dehors des selles".
Mais tu as raison, l’infection peut passer inaperçue dans la plupart des cas et il est tout à fait possible d'abriter le parasite pendant des années sans s'en rendre compte (le ver peut vivre jusqu'à 40 ans). On peut néanmoins observer plusieurs symptômes chez certains sujets : douleurs abdominales, nausées, troubles de l’appétit, éruptions cutanées, fatigue, céphalées… Une perte de poids anormale et rapide peut être également un signe de l’infection.
Cependant, si je suis ta réflexion, il faut également prendre en compte trois choses:
- en Bolivie, on consomme beaucoup de mouton,
- il existe deux types de ténias: solium ou armé (transmis par le porc) et saginata ou interne (transmis par... le boeuf, le mouton, le caribou, le lama, l’antilope, le gnou, la girafe, le lémur, la gazelle, le chameau…).
- à Copacabana, la truite est reine. Mais le poisson est aussi un joli camping à parasites.
En somme, le plus important est de veiller à une cuisson suffisante de la viande afin de détruire les larves de ténia. Pour tous les autres cas, tu prends un risque, minime mais potentiellement dangereux (cysticercose). Perso, je mange tout en voyage. Mais je regarde toujours deux fois avant d'acheter ma nourriture.
Bonjour, ne vous en faites pas, vous ne devriez pas rencontrer de problèmes avec la nourriture la bas. Le seul gros risques viendrait du fait que votre estomac n'est pas habitué à certains plats traditionnels de ce pays ce qui au pire vous donnerait mal au ventre. Si vous suivez les itinéraires touristiques vous n'aurez encore moins le risque que cela se produite. :)
Merci beaucoup pour vos premières réponses. Elles m'éclairent déjà.
En fait, les questions que je me pose sont les suivantes :
- En Bolivie, peut-on faire confiance à de la charcuterie sous cellophane achetée dans une épicerie pour provenir d'un élevage contrôlé ayant subi un contrôle sanitaire ? (et donc pour ne pas être porteuse de tenia solium)
- Le risque de tenia/cysticercose touche t-il uniquement la viande de porc achetée sur le bord d'une rue ou sur un petit marché provenant de petits paysans ?
Ou, en d'autres termes, est-ce que vous mangeriez du jambon de pays (sous cellophane) provenant d'une petite épicerie en Bolivie ? ;-)
Merci d'avance pour vos retour de voyageurs/connaisseurs !
Oui c'est tout a fait possible. Eux aussi ont des normes sanitaires à respecter. (différentes des européennes.) Par contre si vous en achetez en marché, je pense qu'il faut tout de même vous y connaitre un minimum. 🙂
Je viens de lire sur le site de conseils aux voyageurs du ministère: Il est recommandé aux touristes souhaitant se rendre dans la région du Chapare d’utiliser…

I’m planning a trip to Japan next year and I have asthma...
I wanted to know about the regulations regarding Ventolin (Salbutamol) in Japan—is it considered a drug? Can I bring my inhaler with me, or do I need to buy a similar product in Japan?
I have two American cousins. The older one was born in Paris, and his sister was born in California. The latter is planning a trip to Paris this summer, but she recently fell ill, and American doctors don’t know what’s wrong. I had the idea of letting her take advantage of her trip to get treated here, avoiding the high healthcare costs of the American system in the process. The problem is, I can’t find anything online about this—just testimonials from French people who used to be American, but nothing for a simple tourist.
I’m traveling to Portugal with my family and I have a treatment that requires injections. How can I take a flight with these? They look like injectable pens.
Thanks
We’re planning a trip to the Philippines from April 22 to May 8, 2026. Flight from Geneva with a layover in Turkey and Manila. Our itinerary: Angeles – Busuanga – Palawan…
The Philippines are a dream destination, but is it possible to travel there safely? I’ve heard that checked luggage often gets lost, tap water isn’t safe to drink, and mosquitoes are everywhere.
For water, what’s the best solution to carry in a backpack? Is a filtering water bottle 100% reliable?
For mosquitoes, should we treat our clothes with repellent? Are you vaccinated against hepatitis A, malaria, or dengue? Or is there an oral treatment to take?
Hi there,
Does anyone know if there’s travel insurance for someone who’s had a heart attack?
I can’t find an insurer that covers a pre-existing condition, even if it’s stable.
Thanks so much!
Hi everyone, next month my wife, our 6-year-old daughter, and I are flying to Thailand. It’ll be a great chance to soak up some sun—something we’ve been missing lately here in France! But speaking of sun, I burn easily, and our daughter even more so. I was wondering what SPF to get for sunscreen and whether it’s better to buy it there or before we leave? Thanks for your tips!
Hello,
We’re planning to spend 3 months in Madagascar starting in mid-February.
Areas: Mahajanga, Tulear, Diego Suarez, and Sainte Marie—the order isn’t set yet. We’ll either drive for part of the trip or take flights.
We’ve heard all sorts of things about required vaccines and medications (is anti-malarial mandatory?). What’s the exact situation for travelers?
I’ll come back to you for other topics (like finding a reliable driver, among others).
Thank you.
Best wishes to you all,
Nicole
We're about to go on an organized trip to South Africa, including Kruger Park. We were told that Malarone should preferably be taken in the evening at the same time during a meal. But it's hard to know what time we'll have dinner, especially since I've read that in South Africa, dinner is usually around 6 PM.
I'd love to hear from people who've been on organized trips to this destination and could share their experience. We were thinking of taking Malarone around 7:30 PM, assuming dinner would be closer to 7 PM than 6 PM. Also, if the meal ends up being earlier or later than when we take the pill, would a cookie or a piece of bread be enough to take with Malarone?
I’m planning to set off on a "round-the-world" trip/long journey at the start of next year, lasting between 4.5 and 6 months. For now, the itinerary looks like this: South Korea (2 weeks) -> Japan (1 month) -> New Zealand (1 month) -> Argentina (1 month) -> United States (1 month).
I’m on medication (paroxetine 20 mg/day) and was hoping to bring enough for the entire trip so I wouldn’t have to find a doctor on the spot, deal with a molecule that might be slightly different from what’s available in France, or wonder if that’s even a possibility. Basically, it seemed simpler on paper...
But after looking into the regulations for each country, it’s suddenly way less simple . Many seem to only allow the amount corresponding to the length of your "stay" in the country... Which is a problem if I arrive in Korea with 4.5 months’ worth of medication, for example.
After all that, and even though I’ll obviously contact the relevant authorities in each country (fingers crossed for a response 😛), here’s my question:
Has anyone here had any experience with this? (Even if it’s a different medication or different countries, any input would be helpful!)
I’m trying to plan a trip to Dubai with my mom. I’ve seen that some of our medications require prior authorization (sleeping pills, codeine, anti-anxiety meds, etc.).
I’d love to hear from anyone who’s been in our situation. A friend of mine applied to bring her tramadol, but it was denied—though she needed high doses!
Has anyone here gone through this process? Do we *really* need a prescription in English?
We just found out my wife is pregnant, and we’ve planned a trip to the Barlavento Islands in Cape Verde this November.
We’d like to know if there’s a real risk of Zika contamination on those islands, because from what we’ve found online, the recorded cases are old and come from the Sotavento Islands.
We’re thinking about canceling our trip.
If you’ve recently traveled to Cape Verde or live there, do you have any thoughts on this?
hi, I’m looking for information about the possibility of returning to Thailand with a portable liquid oxygen system and whether it’s possible to recharge it in Thailand, especially in Chiang Mai. thanks
I’m starting a new discussion on this topic since there doesn’t seem to be a recent one.
I have several chronic conditions (including asthma and related ones), and I’m planning to travel for a year across different countries.
Generally, I understand it’s possible to travel with approved medications (which should be my case), but often with a limit of 3 months’ worth of treatment.
Since I’m going for 12 months, that means for three-quarters of my trip, I’d have more than 3 months’ worth of medication.
I plan to bring my prescriptions with the INN (International Nonproprietary Name), as well as the original packaging (even though it’s a nightmare, but from what I understand, it’s necessary). But I’m not sure if that’s enough...
Have any of you been in this situation before? How does it work at customs—do I need to declare everything that exceeds the 3-month limit? Do I need a letter from my doctors?
I'm currently in Bangkok: How can I find a good doctor for a consultation? It's for a friend who'd like a second medical opinion compared to what they got in their country of residence.
Any professionals you'd recommend? How much does it cost?
I’ve already visited quite a few countries across several continents, but I’m pretty new to Asia.
I’m planning a trip to Thailand in October or November, and I wanted to check about health precautions: malaria treatment, vaccinations (hepatitis A or others...).
I’ll mostly be in the northern region, around Chiang Mai, where I’ll spend a lot of time in nature and the mountains. Then I’ll head south to Phuket or Krabi and visit Khao Sok National Park. I’ll finish up in Bangkok, with a likely detour to Kanchanaburi.
From what I understand, for a stay of less than 60 days, I don’t need a visa (I’m a French national)? I just need to fill out the TDAC form 3 to 5 days before arrival?
Hi there,
I was wondering if anyone is heading to Cuba soon and could bring me some over-the-counter Sildenafil (viagra) tablets—available at Varadero Airport, among other places.
Hi there! So, I'm hesitating about taking a long trip. I'd like to go away for 2 to 3 months and travel across several continents. I’d love some advice. I often have unexplained allergies and need to follow a daily treatment for my diabetes (insulin). I think I can get authorization from my doctor to travel for 6 months with the treatment—is that correct? After those 6 months, is it possible (instead of bothering a relative to send the medication) to see a foreign doctor to get another 6-month travel authorization? How does it work at the airport? Do I need just one medication transport authorization, or do I have to request a new one in each country (once the treatment runs out) for both the flight and a DCI? Also, travel insurance doesn’t cover chronic illnesses, so will I have to pay for foreign consultations out of pocket? I’m not sure if I explained myself clearly. Oh, and just to repeat—travel insurance doesn’t cover chronic illnesses, so foreign consultations will be at my own expense? Thanks in advance for your help!
Hi everyone.
After years of traveling to the USA without any medical insurance subscriptions—and luckily never having any major health issues (though I did get a scorpion sting buried in the sand at CBSouth, 😇)—life has caught up with us, and we’re now being forced into "wisdom" and leaving our carefree days behind.
So, I’m looking for the best compromise for a 2-month health insurance plan.
I’ve read the discussions on this topic, but the most recent one is from last year, and I’d love your take on the current situation.
I’m familiar with the usual options like Europ Assistance and AXA, but I’ve just discovered Chapka and Heymondo (the latter seems interesting in terms of both price and coverage).
What do you think of these last two? How do they compare in terms of value for money against the bigger companies?
Hi,
We’ve planned a 3-week trip to Bali this summer with our 7-year-old daughter. The itinerary includes Sanur, Nusa Lembongan, Sidemen, Amed, and Ubud. The more time passes, the more we read about people getting sick—some with mild to severe traveler’s diarrhea, and many ending up in the hospital. We, as parents, have been through it in Egypt with pretty bad cases, but we’d really like to avoid that for our daughter. Even though there’s no zero risk, and we’ll be careful, can any of you reassure me? Not everyone got sick, right? I’d love to hear positive feedback from parents, but not just them 😊. Thanks in advance!
Hi there...
I’m traveling with a friend for a month in November.
We booked our round-trip tickets from Paris to Phnom Penh, and yes, I know—it was a mistake. We should’ve flown out of Laos, but here we are.
But is it doable to backpack through both countries in a relaxed way?
I’ve seen that the transport takes a while...
Thanks so much for your replies.
Hi there,
I’ve started looking into getting dental implants, possibly in Costa Rica or Mexico.
Do you have any clinics to recommend or ones I should avoid?
For the next steps, I need to choose between Cuba Medika or Medigo—these are agencies that help with medical procedures. Do you have any info on either of them?
Hi everyone, a question for those who’ve been lucky enough to visit Raja Ampat—should you consider preventive malaria treatment given its proximity to Papua? And how was the food hygiene situation?
Thanks for your feedback! !
For several years now, increased aggression has been observed in Cape fur seals.
At least 70 unprovoked attacks on humans.
It was recently confirmed that this is due to rabies.
The suspected origin is contamination in Namibia by jackals.
The contagion seems to be spreading.
Preventive vaccination (of the animals) is being considered.
Just a reminder:
Rabies affects all mammals.
Once symptoms appear—sometimes weeks or even months later—death is inevitable.
It’s the bite that transmits the disease.
There are so-called "furious" forms with aggression, but also forms without aggression.
In case of a bite, in addition to standard wound care, tetanus prevention… rabies prevention is essential.
Stay careful out there…
Seeing seals from a boat along the coast isn’t rare in these parts…
I need 2 dental implants and I'd like to get them done abroad (it's a question of price).
Thanks for helping me with my search (Turkey, Spain, Romania???)
Can you tell me if you're satisfied with the services provided by Dentist Miguel at Club Amigo in Holguin? I'd like to go there in mid-December. Is it worth the trip to get dental prosthetics done?
Thanks for getting back to me... Michelle from Quebec
Hello,
I’m looking for a dentist who can do a full lower-arch implant with a complete prosthesis. I’m in Quebec and available to travel to Cuba. Need full contact details. Thanks everyone!
My current plan is to get my teeth treated in Cuba, especially for dental implants.
Has anyone here had experience and could refer me to a good, affordable dentist?
I’d really appreciate it if you could give me an idea of the price for one implant, since I need at least 6 done.
Thanks so much!
