Drug-resistent bacteria are known to arise as a result of antibiotics added to animal feed. Sometimes these bacteria are present in foods, such as ground beef, from animal sources. Recent research has confirmed that genes for drug resistance spread to other species of bacteria in the human intestine following the ingestion of resistant bacteria. What processes allow these genes to move from species to species of bacteria? What can be done to reduce the significance of this problem?
