Beef/ja: Difference between revisions

[[Beef cattle]] are raised and [[Cattle feeding|fed]] using a variety of methods, including [[feedlot]]s, [[free range]], [[ranch]]ing, [[backgrounding]] 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'' contaminations 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 [[Antibiotic use in livestock|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. In 2023 production was forecast to peak by 2035.
