Mexico's chicken culling at more than two million in Guanajuato
Mexico has witnessed more than two million chickens slaughtered in the Guanajuato state due an outbreak of bird flu.
Food safety services are carrying out inspections of poultry farms and have vaccinated thousands of chickens.
Egg and poultry prices have gone up in some areas.
The current outbreak of bird flu was caused by an "exotic" virus that affects birds but poses no threat to humans.
