Characteristics related to biosafety
The chicken is a domesticated fowl, a subspecies of the Red Junglefowl. The Red Junglefowl (Gallus gallus) is a tropical member of the Phasianidae family. It is thought to be ancestral to the domestic chicken, with some hybridzation with the Grey Junglefowl.

The Red Junglefowl was first domesticated at least five thousand years ago in Asia, then taken around the world, and the domestic form is kept globally as a very productive food source of both meat and eggs.

The range of the wild form stretches from Tamil Nadu, South India eastwards across southern China and into Malaysia, the Philippines and Indonesia. Junglefowl are established on several of the Hawaiian Islands, but these are feral descendants of domestic chickens. They can also be found on Christmas Island and the Marianas.
EN
More than 50 billion chickens are globally reared annually as a source of food, for both their meat and their eggs. The vast majority of poultry are raised using intensive farming techniques.
