Travelling for the food is pure joy: sizzling skewers from a night market, dumplings steamed to order, a once-in-a-lifetime tasting menu. The only thing that ruins a culinary itinerary fast is getting ill, especially if you’re hopping cities, booking tours, or travelling with family.
The good news: you don’t have to avoid local food to stay well. With a few smart habits and the right travel vaccines, you can eat adventurously while reducing your risk of food- and water-borne illnesses.
Why food-focused travel can make you ill
When you travel, your gut meets unfamiliar bacteria, different food handling standards, new ingredients, and (in some countries) different water treatment. Risk tends to come from:
- Undercooked foods (especially poultry, eggs, seafood)
- Cross-contamination (raw and cooked foods mixing)
- Unwashed produce
- Untreated water and ice
- Food held warm for long periods in hot climates
Most stomach bugs settle, but some infections can be severe, and a few are vaccine-preventable (especially relevant if you’re planning markets, street food tours, or rural stops).
Street food: how to eat boldly and choose wisely
Street food is often safest when it’s cooked fresh and served hot. Use these quick checks:
Choose the right stall
- Follow the queue: high turnover usually means fresher food.
- Watch it cooked: ideally from raw to steaming hot in front of you.
- Hot beats warm: “piping hot” is safer than “kept warm”.
- Clean setup: covered ingredients, clean surfaces, minimal bare-hand contact.
Better bets:
- Stir-fries cooked to order
- Grilled skewers cooked through
- Fresh soups and broths served hot
- Steamed dumplings
- Fruit you can peel yourself (banana, orange, mango)
Be cautious with:
- Buffets and dishes sitting out
- Cut fruit left uncovered
- Cold salads, raw garnishes
- Raw/undercooked seafood (oysters, ceviche)
- Sauces left out all day (especially creamy or dairy-based)
Fine dining isn’t automatically risk-free
High-end restaurants can still catch travellers out, mainly with raw or lightly cooked dishes and unpasteurised products.
If you’re in a higher-risk destination (or you’ve had stomach issues in the past), consider:
- Asking for well-cooked meat and seafood
- Being cautious with tartare/carpaccio, raw oysters, runny eggs
- Avoiding unpasteurised milk/cheese (especially important in pregnancy)
Water and ice: the sneaky culprit
In many destinations, travellers get ill more often from water than food.
Safer water habits
- Use sealed bottled water (check the seal is intact).
- If unsure, use bottled water to brush your teeth.
- Avoid ice unless you trust it’s from treated water.
- Consider a reputable filter bottle for remote trips.
- Tea/coffee made with boiled water is typically safer, as long as it’s served hot.
Hand hygiene that actually makes a difference
This is one of the biggest risk reducers, and it’s easy to forget mid-market.
• Wash with soap and water before eating.
• If you can’t, use hand sanitiser (60%+ alcohol) and cover all hand surfaces.
• Sanitise before you touch snacks (not just after you’ve handled money).
A simple “food-smart” travel routine
Small choices add up:
- Morning: choose cooked breakfast items; be cautious with foods that rely on refrigeration.
- Midday: peak heat = higher risk if food sits out; prefer made-to-order dishes.
- Evening: try the “adventurous” stuff when you’re not about to take a long bus/boat/flight.
Travel vaccines for food lovers (especially street food and markets)
If your trip includes street food, night markets, food tours, backpacking, rural travel, or visiting friends and relatives, it’s worth discussing vaccines that protect against illnesses commonly linked to food and water.
The key ones many travellers ask about are:
- Typhoid vaccine
- Hepatitis A vaccine
- Cholera vaccine (for selected higher-risk itineraries)
A travel consultation helps match vaccines to your destination, trip style, medical history, and timing.
Typhoid vaccine: the big one for culinary travel
Typhoid fever is usually caught through contaminated food and water. Risk tends to be higher where sanitation varies and it increases if you’re eating widely in local settings, trying street food daily, travelling independently, or heading to smaller towns and villages.
Who should strongly consider the typhoid vaccine?
Typhoid vaccination is particularly worth discussing if you’re:
- Planning street food tours, markets, or lots of local eateries
- Backpacking, camping, or travelling more “off the beaten path”
- Staying for longer trips or multi-country itineraries
- Visiting friends and relatives (VFR travel), including home-cooked community events
Typhoid vaccine: how it’s given
Most UK travellers receive typhoid as an injection. Your clinician will advise what’s suitable for your age, health, and timeline.
When to get the typhoid vaccine before travel
Aim to have it at least 2 weeks before departure where possible, so your immune system has time to respond. Earlier is even better if you’re planning a full travel vaccine schedule.
How long does the typhoid vaccine last?
Protection isn’t lifelong. If you travel regularly to higher-risk areas, you may need boosters. Your travel nurse will confirm the schedule based on the vaccine used and your travel pattern.
Typhoid vaccine side effects (what to expect)
Most side effects are mild and short-lived, such as:
- Sore arm/redness where injected
- Mild fever or fatigue
- Headache or achiness
Important: Even with the typhoid vaccine, food and water hygiene still matters, vaccines reduce risk, they don’t replace sensible eating choices.
Hepatitis A vaccine: a common food-and-water risk
Hepatitis A is a liver infection that can be caught from contaminated food and drink (and sometimes close contact). It’s one of the most commonly recommended travel vaccines for many destinations.
Hepatitis A vaccine schedule
Many people start with one dose for short-term cover, then complete a second dose later for longer-lasting protection. Timing depends on how soon you’re travelling and your personal risk profile.
Cholera vaccine: for higher-risk itineraries
Many travellers won’t need cholera vaccination, but it may be considered if you’re travelling to areas with disrupted water/sanitation, staying for longer periods, working in aid/health settings, or following a higher-risk itinerary.
Cholera vaccination is typically an oral course (a drink), taken before travel. Your clinician will advise if it’s appropriate for your destination and plans.
Pack a “tummy toolkit” for culinary adventures
A small kit can turn a miserable day into something manageable:
- Oral rehydration salts (ORS) (often the most useful)
- Hand sanitiser
- Thermometer
- Rehydration-friendly snacks (plain crackers, electrolyte tabs)
- Anti-diarrhoeal medication (use carefully — see below)
A quick note on anti-diarrhoeal medicines
They can help you get through a travel day, but they’re not ideal if you have a high fever or blood in the stool, and they don’t replace hydration. If you have underlying conditions, are pregnant, or travelling with children, get tailored advice.
What to do if you get traveller’s diarrhoea
Most cases improve within a few days. Prioritise:
- Hydration first (ORS + small frequent sips)
- Rest
- Gentle foods as tolerated (rice, bananas, toast, soups)
Seek urgent medical help if you have:
- Signs of dehydration (dizziness, fainting, very dark urine)
- High fever
- Blood in stool
- Severe abdominal pain
- Symptoms not improving after a few days
- Higher-risk situations (pregnancy, immunocompromised travellers, young children)
Quick checklist: eat everything (safely)
Before you go
- Book a travel consultation (ideally 4–8 weeks before travel if possible)
- Discuss typhoid vaccine, hepatitis A vaccine, and cholera vaccine where relevant
- Pack ORS + sanitiser
- Plan safe drinking water
While you’re there
- Choose busy stalls; hot cooked food
- Peel fruit yourself
- Be cautious with ice and salads
- Sanitise before eating
