Beef mince, ground beef, hamburger meat (in North America), hamburg (in New England) or minced meat (elsewhere) is a minced meat food, made of beef finely chopped by a mincer. It is used in many recipes including hamburgers and cottage pie. In some parts of the world a mincer is sometimes called a meat grinder, although the device works by a process of fine chopping (mincing) and not grinding.

In many countries, food laws define specific categories of beef mince and what they can contain. For example, in the United States, beef fat may be added to hamburger, but not to ground beef if the meat is ground and packaged at a USDA-inspected plant.[1] A maximum of 30% fat by weight is allowed in either hamburger or ground beef. Both hamburger and ground beef can have seasonings, but no water, phosphates, extenders, or binders added. Ground beef is often marketed in a range of different fat contents, to match the preferences of different customers.
Beef mince is usually made from leaner, tougher and less desirable beef created when the sides of beef are carved into steaks and roasts.[2] About 17-18% of US ground beef comes from dairy cows.[3][4]
In a study in the USA in 2008, eight different brands of fast food hamburgers were evaluated for water content by weight and recognizable tissue types using morphological techniques that are commonly used in the evaluation of tissue's histological condition. The study found that the content of the hamburgers included:
Recent meat processing methods employed companies such as Beef Products Inc., have led to the inclusion of "pinkish slime" (a trimmings meat product that has been separated using a centrifuge and treated with ammonia to remove salmonella and other pathogens) in a wide variety of ground beef products in the USA. This product has been included in US meat products since 2001.[6]
Although any cut of beef may be used, chuck steak is one of the most popular choices (because of its richness of flavor and balance of meat and fat). Round steak is also frequently used.
Ground beef is usually subdivided based on the cut and fat percentage:[7]
Ground beef is popular as a relatively cheap and quick-cooking form of beef. Some of its most well known uses are in hamburgers, sausages or cottage pie in Britain. It is an important ingredient in meatloaf, sloppy joes, taco, and Midwestern cuisine. Italians use it to make meat sauces, for example, lasagna and spaghetti bolognese. In the Middle East, it is used to make spicy kofta and meatballs. The Scottish dish mince and tatties uses it along with mashed or boiled potatoes. In Lancashire, particularly Oldham, minced meat is a common filling for rag puddings. The Dutch slavink consists of ground beef (half beef, half pork) rolled in bacon.
Raw lean ground beef is used to make steak tartare, a French dish. More finely diced and differently seasoned, it is popular as a main course and as a dressing in Belgium, where it is known as filet américain ("American fillet").
Picadillo is a Spanish term for ground beef, and is a common ingredient in several Latin American cuisines. Picadillo with chili pepper and finely diced onion and potato is a common filling for tacos and gorditas in Mexico.
Food safety of ground meat issues are due to possible bacterial contamination. Undercooked Jack in the Box hamburgers contaminated with E. coli O157:H7 were responsible for four deaths and the illness of hundreds of people in 1993.[8] Minced beef must be cooked to 72 °C (160 °F) to ensure that all bacterial contamination, whether it be endogenous to the product or contaminated after purchasing by the consumer, is killed. Cooked color does not always indicate the beef has reached the required temperature, as beef can brown before reaching 68 °C (155 °F).[9] Thus, a thermometer should be used to verify the required temperature has been reached. Contrarily, beef exposed to nitric oxides from open flames (wood, charcoal, propane, etc.) during grilling can remain pink after reaching temperature. The color usually is limited to the surface, so can be distinguished from undercooked meat.
