The meat industry are the people and companies engaged in modern industrialized livestock agriculture for the production, packing, preservation and marketing of meat (in contrast to dairy products, wool, etc.). In economics, the meat industry is a fusion of primary (agriculture) and secondary (industry) activity and hard to characterize strictly in terms of either one alone. The greater part of the meat industry is the meat packing industry – the segment that handles the slaughtering, processing, packaging, and distribution of animals such as poultry, cattle, pigs, sheep and other livestock.
A great portion of the ever-growing[1] meat branch in the food industry involves intensive animal farming in which livestock are kept almost entirely indoors[2] or in restricted outdoor settings like pens. Many aspects of the raising of animals for meat have become industrialized, even many practices more associated with smaller family farms, e.g. gourmet foods such as foie gras.[3][4] The production of livestock is a heavily vertically integrated industry where the majority of supply chain stages are integrated and owned by one company.[citation needed]
