Vietnam is a street food paradise — flavorful, affordable, and found on nearly every corner. From sizzling grills to colorful sidewalk stalls, every bite promises adventure. But while indulging in local specialties is a must-do, not every dish is a safe bet for travelers. Without local know-how, some foods may cause stomach discomfort — or worse — turning your culinary journey into a cautionary tale.

That’s why we’ve created this essential guide: to help you confidently navigate Vietnam’s vibrant street food scene. In this blog, you’ll discover 10 dishes you may want to avoid (or approach with caution), along with practical food safety tips to help you eat like a local — and stay healthy doing it. Because nothing should ruin your trip faster than a bowl of regret.

Why Street Food Safety Matters in Vietnam?

High temperatures, open-air markets, and fast-paced prep

Street food is the heart of Vietnamese cuisine — it’s flavorful, affordable, and served fresh right on the street. However, the same open-air settings, hot climates, and quick preparation methods that make it appealing can also create ideal conditions for bacterial growth and cross-contamination, especially when hygiene practices are inconsistent.

Common issues: stomach flu, food poisoning, hygiene concerns

For tourists, this can mean an unexpected case of stomach flu, mild food poisoning, or digestive discomfort. These issues are often caused by undercooked meat, unrefrigerated ingredients, or unsanitary cooking conditions — all of which can be hard to spot as a first-time visitor.

Sensitive travelers or those with weak digestion

Travelers with sensitive digestion, children, or the elderly should be especially cautious. Even seemingly harmless street snacks can cause problems if their immune systems aren’t prepared for unfamiliar bacteria or spicy ingredients.

Top 10 Risky Dishes And Their Alternatives

1. Tiết canh (Raw Blood Pudding)

Not many people, even Vietnamese, can handle eating tiet canh (raw blood pudding), but those who can often become addicted to this. Since it’s made from raw animal blood, it carries a high risk of causing illness. The danger may come from unhygienic preparation or from the animals themselves (pigs or ducks) carrying harmful pathogens. If you’re curious but cautious, you can try boiled blood pudding instead—it’s essentially the same, but cooked.

2. Raw Seafood (especially oysters, clams)

Raw seafood—especially oysters and clams - is a beloved delicacy for many, offering a taste of the ocean’s freshness. However, like all culinary experiences, enjoying it safely enhances the pleasure. To savor these treats worry-free, consider trying them grilled, steamed, or in a hotpot—methods that bring out their natural sweetness while ensuring optimal safety. With just a little care in preparation, you can still enjoy the unique charm of shellfish as part of your Vietnamese food journey.

3. Trứng vịt lộn (Fertilized Duck Egg / Balut)

While nutritious and rich in flavor, the partially developed embryo in fertilized eggs can be a bit overwhelming for first-timers or those with sensitive stomachs. For a gentler introduction, try trứng cút lộn xào me—quail eggs stir-fried in tamarind sauce. This popular dish strikes a delightful balance between sweet, sour, and savory, offering a uniquely Vietnamese taste experience that’s both approachable and delicious.

4. Uncooked Herbs or Ice in Unknown Eateries

Fresh herbs and cool ice are staples of Vietnamese cuisine, enhancing both flavor and refreshment. However, in lesser-known eateries, they might be washed or made with tap water, which could pose a risk to sensitive stomachs. To fully enjoy these elements with peace of mind, choose reputable restaurants where herbs are carefully cleaned and ice is made from purified water—ensuring both safety and authentic taste.

5. Street Grilled Meat without Reheating

Street-side grilled meat is a flavorful highlight of Vietnam’s culinary scene, often tempting with its smoky aroma and sizzling skewers. To enjoy it safely and at its best, consider asking the vendor to reheat the meat before serving. This simple step ensures your bite is both warm and safe, letting you savor the full flavor with peace of mind. Freshly grilled options are also a great choice if you’re craving something straight off the fire.

6. Toad 

Toad meat can be potentially dangerous if not prepared properly, as the skin and certain internal organs contain bufotoxins—natural toxins that can cause serious health issues. Instead, opt for frog meat (thịt ếch), a popular and much safer alternative in Vietnamese cuisine. It’s not only safe when cooked well but also surprisingly delicious and worth trying.

7. Pre-peeled Fruits Sold on the Street

Vietnam’s tropical fruits are a must-try for any visitor, offering vibrant colors and refreshing flavors. While pre-peeled fruits on the street may look convenient, they can be exposed to dust and insects. For a safer and equally delicious experience, opt for whole fruits and peel them yourself. It’s a simple way to enjoy nature’s sweetness with confidence—and a fun part of the local food adventure.

8. Fermented Dishes—Shrimp paste (mắm tôm) 

Vietnamese cuisine is renowned for its rich, complex flavors—especially in its fermented sauces. While dishes like mắm tôm may be bold for first-time visitors due to their strong aroma and taste, there’s no need to shy away completely. Instead, start with milder options like mắm nêm or nước mắm chua ngọt, which are often cooked into dishes and offer a more balanced, approachable flavor. It’s a great way to ease into the fascinating world of Vietnamese condiments.

9. Milk-based Drinks in Open-Air Settings

Vietnam’s vibrant street drink culture offers plenty of refreshing options, including milk-based beverages like smoothies and yogurt drinks. However, due to the country’s warm climate, it’s best to enjoy these treats from reputable cafes or vendors with proper refrigeration. This ensures your drink stays fresh, cool, and safe to enjoy—so you can sip worry-free and soak up the tropical vibes.

10. Strange Meat (Dog, Cat and others)

Vietnamese cuisine is incredibly diverse, and for some, that includes meats considered unconventional in other cultures—such as dog, cat, or even snake and field rat. While these dishes may be part of certain regional or traditional practices, they often spark debate and discomfort among international travelers.

Beyond cultural differences, it’s worth noting that some of these meats, especially dog and cat, can pose health risks. Improper handling or preparation may lead to exposure to parasites that can migrate to vital organs like the liver or lungs.

If you’re curious about Vietnam’s more adventurous dishes, it’s best to explore with caution, stick to reputable eateries, and consider safer alternatives that still offer bold, authentic flavors—without the ethical or health concerns.

General Food Safety Tips for Eating in Vietnam

Personal Hygiene - What You Can Do to Stay Safe

Keeping yourself clean is the first step toward staying healthy while enjoying Vietnam’s vibrant street food. Always wash your hands or use alcohol-based hand sanitizer before and after eating. It’s also wise to carry wet wipes or tissues, especially when dining outdoors. Avoid touching your mouth or face during meals, and drink bottled water instead of tap water. These small precautions can make a big difference in preventing foodborne illnesses.

How to Choose a Safe Place to Eat

When in doubt, follow the locals — eateries that attract crowds are usually trustworthy. Look for stalls that prepare food fresh on the spot, with proper covering for ingredients and clean cooking utensils. Avoid places where food has been sitting out too long or where hygiene practices look questionable. A little observation can help you enjoy street food with peace of mind.
