Beef is the culinary name for meat from cattle (Bos taurus). :beef:

In prehistoric times, humans hunted aurochs and later domesticated them. Since that time, numerous breeds of cattle have been bred specifically for the quality or quantity of their meat. Today, beef is the third most widely consumed meat in the world, after pork and poultry. As of 2018, the United States, Brazil, and China were the largest producers of beef.

Beef can be prepared in various ways; cuts are often used for steak, which can be cooked to varying degrees of doneness, while trimmings are often ground or minced, as found in most hamburgers. Beef contains protein, iron, and vitamin B12. Along with other kinds of red meat, high consumption is associated with an increased risk of colorectal cancer and coronary heart disease, especially when processed. Beef has a high environmental impact, being a primary driver of deforestation with the highest greenhouse gas emissions of any agricultural product.

- History:
People have eaten the flesh of bovines since prehistoric times; some of the earliest known cave paintings, such as those of Lascaux, show aurochs in hunting scenes. People domesticated cattle to provide ready access to beef, milk, and leather. Cattle have been domesticated at least twice over the course of evolutionary history. The first domestication event occurred around 10,500 years ago with the evolution of Bos taurus. The second was more recent, around 7,000 years ago, with the evolution of Bos indicus in the Indus Valley. There is a possible third domestication event 8,500 years ago, with a potential third species Bos africanus arising in Africa.

In the United States, the growth of the beef business was largely due to expansion in the Southwest. Upon the acquisition of grasslands through the Mexican–American War of 1848, and later the expulsion of the Plains Indians from this region and the Midwest, the American livestock industry began, starting primarily with the taming of wild longhorn cattle. Chicago and New York City were the first to benefit from these developments in their stockyards and in their meat markets.

-Production:
Beef cattle are raised and fed using a variety of methods, including feedlots, free range, ranching, back-grounding and intensive animal farming. Concentrated Animal Feeding Operations (CAFOs), commonly referred to as factory farms, are commonly used to meet the demand of beef production. CAFOs supply 70.4% of cows in the US market and 99% of all meat in the United States supply. Cattle CAFOs can also be a source of E. coli contamination in the food supply due to the prevalence of manure in CAFOs. These E. coli contamination's include one strain, E. coli O157:H7, which can be toxic to humans, because cattle typically hold this strain in their digestive system. Another consequence of unsanitary conditions created by high-density confinement systems is increased use of antibiotics in order to prevent illness. An analysis of FDA sales data by the Natural Resources Defense Council found 42% of medically important antibiotic use in the U.S. was on cattle, posing concerns about the development of antibiotic resistant bacteria.
