Eating raw beef carries real risk of foodborne illness, and no health authority considers it fully safe. That said, certain raw beef dishes like steak tartare and carpaccio have long traditions in restaurants worldwide, and the actual danger varies dramatically depending on the cut, sourcing, preparation, and who’s eating it. Here’s what you need to know to make an informed decision.
Why Raw Beef Is Risky
Raw beef can harbor a range of harmful bacteria, including E. coli, Salmonella, Campylobacter, and Listeria. These pathogens cause gastrointestinal illness ranging from a few days of misery to hospitalization or worse. E. coli O157, one of the more dangerous strains, is strongly associated with beef. CDC source attribution data from 2022 found that over 85% of E. coli O157 illnesses were linked to just two food categories: leafy greens and beef.
Beyond bacteria, raw beef also carries a parasite risk. The beef tapeworm (Taenia saginata) infects humans who eat raw or undercooked beef. Once inside you, it can grow up to 10 meters long and cause abdominal pain, weight loss, and digestive problems. The most visible sign is passing segments of the worm in your stool. Beef tapeworm infections are more common in Eastern Europe, Russia, eastern Africa, and Latin America, and relatively rare in the United States, but the risk exists wherever contaminated beef is consumed raw.
Whole Cuts vs. Ground Beef
Not all raw beef carries the same level of risk. The distinction between a whole muscle cut (like a steak) and ground beef is significant. On a whole piece of meat, bacteria typically live only on the outer surface. That’s why searing a steak’s exterior is usually enough to kill off surface contamination, even if the center stays pink or red. Ground beef is a different story entirely: the grinding process mixes any surface bacteria throughout the meat, distributing it into the center of every patty or portion. This is why the USDA sets a higher safe cooking temperature for ground beef (160°F) compared to whole cuts like steaks, chops, and roasts (145°F with a three-minute rest).
If you’re considering eating any beef raw, ground beef is the highest-risk option. Steak tartare, despite being a raw ground preparation, is typically made from whole cuts that are hand-chopped or ground to order in the kitchen, not from pre-ground supermarket beef that’s been through industrial processing and may contain meat from many different animals.
How Restaurants Reduce the Risk
Raw beef dishes do exist on menus around the world, from French steak tartare to Italian carpaccio to Ethiopian kitfo. Poisoning from steak tartare is relatively rare, largely because it’s typically served in higher-end restaurants with strict hygiene standards and reliable meat suppliers. These kitchens select specific whole muscle cuts, keep them at proper temperatures, and prepare them immediately before serving.
Japan offers a useful case study in how seriously some countries take raw beef safety. After foodborne illness outbreaks, Tokyo established legally binding standards in 2011 for any beef sold to be eaten raw. The rules require that meat test negative for harmful bacteria, that the outer surface be heat-sterilized to a depth of 1 centimeter at 60°C for at least two minutes, and that the meat then be rapidly cooled to 4°C or below. Records of sterilization must be kept for a year. Raw beef liver was banned outright for sale or serving in 2012 after no effective safety measure could be found for it. Even with all these precautions, Japanese labeling standards still warn that eating raw meat carries inherent risk.
These are far more rigorous protocols than anything a home cook would realistically follow, which highlights the gap between professionally prepared raw beef and what you might attempt in your own kitchen.
Who Should Never Eat Raw Beef
Certain groups face significantly higher stakes from foodborne illness. The CDC classifies raw or undercooked meat as a “riskier choice” for anyone with a weakened immune system. That includes people with diabetes, liver or kidney disease, HIV, autoimmune disorders like lupus, or anyone undergoing chemotherapy or radiation. Pregnant women, young children, and older adults also fall into this higher-risk category. For these groups, the body’s ability to fight off infections is reduced, turning what might be a rough few days for a healthy adult into something potentially life-threatening.
Lowering Your Risk at Home
If you choose to eat raw beef despite the risks, a few practical steps can reduce (though never eliminate) the danger.
- Choose whole muscle cuts, never ground beef. A solid piece of steak has bacteria concentrated on the surface, which you can trim away. Pre-ground beef has potential contamination mixed throughout.
- Buy from a trusted source. Talk to your butcher. Some shops sell cuts specifically intended for raw preparations and can tell you about sourcing and handling. Supermarket meat packaged for cooking isn’t selected or handled with raw consumption in mind.
- Keep it cold. Fresh beef steaks can be refrigerated at 40°F or below for three to five days, but if you plan to eat it raw, use it as soon as possible after purchase. Ground beef has an even shorter window of one to two days in the fridge.
- Trim the exterior. Cutting away the outer surfaces of a whole muscle cut removes the area most likely to carry bacteria. This is the principle behind Japan’s requirement to heat-sterilize the outer centimeter.
- Use clean tools and surfaces. Cross-contamination from cutting boards, knives, and hands is a major source of foodborne illness. Sanitize everything that contacts the meat.
The Bottom Line on Safety
No preparation method makes raw beef completely safe. Cooking to the USDA’s recommended internal temperatures is the only reliable way to kill the bacteria and parasites that beef can carry. That said, millions of people eat raw beef dishes without getting sick, particularly when the meat comes from reputable sources, is a whole muscle cut rather than ground, and is handled with care. The risk is real but context-dependent. For a healthy adult eating hand-cut tartare at a reputable restaurant, the odds of illness are low. For someone with a compromised immune system eating pre-ground supermarket beef at home, those odds climb considerably.
