Food Safety & Dietary Restrictions in China

Eating in China is one of the best parts of any trip, and for most visitors it goes smoothly. The food is fresh, the variety is huge, and serious problems are uncommon if you use basic judgment. That said, a few things genuinely matter: don't drink the tap water, know how to read a restaurant's hygiene rating, and have a plan for communicating allergies or dietary needs in a language you probably don't speak. This guide covers what's worth worrying about, what isn't, and exactly what to do in each case.

How risky is eating in China, really?

Honest answer: low to moderate. Travelers' diarrhea (TD) is the most common food-related issue, and China sits in the intermediate-risk range. According to clinical data summarized in gastroenterology literature, roughly 8–20% of visitors experience some diarrhea during the first two weeks of a stay, with luxury accommodation falling at the lower end of that range. That's not a reason to panic. It's a reason to be sensible about water and a few specific foods.

The bigger picture is that China has a serious regulatory framework behind its food supply. The Food Safety Law of the People's Republic of China has been in force since 2009 (replacing the older Food Hygiene Law) and has been revised several times since, including major updates in 2015 and 2021. Among other things, it lets consumers claim compensation from producers or sellers of harmful food, up to ten times the price paid. Enforcement varies in practice, but the system exists and large cities take it seriously.

Tap water: don't drink it

This is the one rule that's non-negotiable. The U.S. CDC is explicit that tap water in mainland China, including major cities, is not safe to drink directly. Hong Kong is the exception. Everywhere else, stick to bottled water or water that's been boiled.

China does have a national standard for drinking water quality (GB 5749-2022, a mandatory standard in force since April 2023), and the water leaving treatment plants is treated. The problem is what happens between the plant and your glass: older pipes, rooftop tanks, and building plumbing mean it's not reliable at the tap. Locals boil water before drinking it for exactly this reason.

The good news is that staying hydrated is easy and cheap. Bottled water is everywhere, starting around ¥2 for a standard bottle. Common brands include Nongfu Spring (农夫山泉), Nestlé, C'estbon (怡宝), Evian, Kunlun Mountain (昆仑山), and Wahaha (娃哈哈). Most hotels provide free bottled or boiled water in the room. Airports, train stations, and trains themselves have hot and cold drinking-water dispensers (the hot water is boiled and safe) — bring your own bottle or cup and you can refill for free.

Street food: usually fine if you pick well

Street food (街边小吃, jiēbiān xiǎochī) is a highlight, and avoiding it entirely would mean missing some of China's best eating. The trick is choosing the right stall, not avoiding the category. A few reliable signals:

• Look for a line, especially of locals. High turnover means fresh ingredients and food that hasn't been sitting out.
• Eat it hot and freshly cooked. Anything pulled straight off the wok, grill, or boiling pot is low-risk. Steam rising is a good sign.
• Watch it being made. Vendors who cook to order in front of you are a safer bet than pre-prepared trays.
• Skip pre-cut fruit and raw salads. These are washed in tap water and handled a lot. Buy whole fruit you peel yourself instead.

If you're picky about utensils, carry your own chopsticks or use disposable ones, which most stalls have. For more on where to find the best of it, see our guide to the best street food cities in China.

Reading restaurant hygiene ratings: the smiley face system

Here's something genuinely useful that most visitors don't know. Restaurants in China are required to display a food-safety rating in the form of a cartoon face, introduced under national guidance from the former State Food and Drug Administration. The faces are easy to read at a glance:

The card is usually posted near the entrance or the counter. As a simple rule, favor the smiling face. Some cities go further. Shanghai, for example, keeps the three-level daily (dynamic) rating but adds an annual grade of A, B, C, or D, where a D is reserved for places that have caused food poisoning or been ordered to suspend operations. You can read the official Shanghai breakdown on the city's market regulation bureau site if you want the detail.

Foods to be careful with

A short, specific list beats vague worry. The CDC advises travelers to China to strictly avoid:

• Undercooked or raw fish and shellfish. This includes some street and market preparations. Parasites and bacteria are real risks here.
• Unpasteurized dairy. Stick to sealed, branded, pasteurized milk and yogurt.

Beyond that, the street-food principles apply: hot and freshly cooked is your friend, and pre-cut produce and cold dishes that have been sitting out are the things to skip. Typhoid risk is low in major cities but worth a vaccine conversation with your doctor if you're heading to rural areas or staying with friends and relatives. (Paratyphoid is more common in China and there's no vaccine for it, which is another reason the basic food precautions matter.)

If you do get sick

Most travelers' diarrhea is mild and clears on its own in a day or two. The priorities are staying hydrated and not making it worse.

• Rehydrate. Oral rehydration salts (ORS, 口服补液盐, kǒufú bǔyè yán) are the gold standard for replacing fluids and electrolytes, and they're cheap and widely available at Chinese pharmacies. Mix them only with sealed, bottled, boiled, or purified water — never straight tap water.
• Self-treat symptoms. The CDC suggests travelers carry loperamide for symptom relief, and, for higher-risk trips, an antibiotic from your doctor to keep on hand for severe cases. Sort this out before you leave home.
• Know when to escalate. High fever, blood in your stool, or symptoms lasting more than a couple of days mean you should see a doctor rather than wait it out.

Dietary restrictions: allergies

This is where preparation pays off most. China does not have the allergen-labeling culture you may be used to at home, and a casual verbal request can easily get lost in translation or simply not taken seriously. Take ownership of communicating it clearly.

The basic phrase is straightforward: 我对 X 过敏 (wǒ duì X guòmǐn), "I'm allergic to X." For peanuts, that's 我对花生过敏 (wǒ duì huāshēng guòmǐn). The word 过敏 (guòmǐn) works as both noun and verb.

Practical steps for serious allergies:

• Carry a printed or phone-saved allergy card in clear Simplified Chinese, naming your allergen and the consequence.
• Show it at ordering and, if you can, ask the kitchen to confirm.
• Carry your own medication, including an epinephrine auto-injector if prescribed — don't assume you can buy an equivalent locally.
• Lean toward simpler dishes you can see being cooked over complex sauces with hidden ingredients.

Dietary restrictions: halal

Halal food (清真, qīngzhēn) is widely available in China, especially in Beijing, Xi'an, Shanghai, and areas with significant Hui Muslim populations. The ubiquitous Lanzhou beef noodle (兰州拉面) shops are very often halal. To find places nearby, search "清真" on Amap (高德地图) or Dianping (大众点评).

The thing to watch for is hidden pork, which turns up in more dishes than you'd expect: lard, pork floss (肉松), oyster sauce, chicken bouillon powder (鸡精), and broths that may be made with pork bones. On packaged foods, look for the 清真 label. We cover the topic in depth in our dedicated halal food in China guide.

Dietary restrictions: vegetarian and vegan

Eating vegetarian (吃素, chī sù) in China is doable, with one twist. The concept is closely tied to Buddhism, and traditional Buddhist vegetarian cooking avoids the "five pungent" aromatics (garlic, onion, ginger, coriander and similar), which isn't what most Western vegetarians mean. Meanwhile, broths and stir-fries that look vegetarian are often made with meat stock or lard.

One counterintuitive point: strict vegans sometimes have an easier time than ovo-lacto vegetarians, because Buddhist temple restaurants serve fully plant-based food. Be specific about what you do and don't eat rather than relying on the word "vegetarian." Our vegetarian and vegan guide goes into how to order and what to look out for.

Ordering with the language gap in mind

A lot of food-safety and dietary success in China comes down to communication. A translation app, a few written cards, and pointing at picture menus go a long way. If you're not confident ordering, read how to order food with zero Chinese before you go — it'll make every meal less stressful and help you steer clear of ingredients you're trying to avoid.

Frequently asked questions

Can I brush my teeth with tap water?

For most people, yes. If you're cautious or have a sensitive stomach, use bottled or boiled water. The real risk is from drinking it, not brief contact.

Is street food actually dangerous?

Not if you choose well. Busy stalls with high turnover, food cooked to order in front of you, and anything served piping hot are low-risk. Pre-cut fruit, raw salads, and stalls with no customers are what to avoid.

How do I complain about a restaurant's hygiene?

China's national consumer complaint hotline is 12315 (run by the State Administration for Market Regulation), which handles food-safety complaints. There's also a national tourism service hotline, 12301, and a 24/7 non-emergency help line, 12345. Numbers and service scope can change, so confirm the latest before relying on them.

Should I take probiotics or charcoal tablets?

Oral rehydration salts and loperamide are the evidence-backed basics; pack those. Activated charcoal is sold cheaply in Chinese pharmacies and gets mentioned a lot in travel blogs, but its effectiveness for travelers' diarrhea isn't well established by medical sources, so don't rely on it as a treatment.

Do I need a typhoid vaccine?

Risk is low in major cities. If you're visiting rural areas or staying with local families, talk to a travel-medicine doctor before your trip. Check the latest CDC guidance for China as recommendations can change.

The bottom line

Eating in China is safe enough that you should dig in, not safe enough to switch your brain off. Drink bottled or boiled water and skip the ice at sketchy spots. Choose busy stalls and eat food hot. Glance at the smiley-face rating before sitting down. Avoid raw fish, shellfish, and unpasteurized dairy. And if you have allergies or a specific diet, do the prep work: carry a Chinese-language card, pack your own medication, and confirm rather than assume. Get those basics right and the worst you'll likely face is a mild upset stomach — a small price for some of the best food anywhere. Before you travel, check the latest CDC health notices for China and confirm any emergency or hotline numbers.
