text: Migrating birds tend to stop on their journey on local lakes and water reservoirs where if they have with them a bird flue virus then they may contaminate the local surroundings and local animals and birds with that virus which in turn can be transmitted to poultry farms where it may infect the poultry birds. When a human being consumes a bird flu virus infected Bird then he may get infected bird Flu.However if the Chicken is cooked above 80 degree Celsius temperature the virus is unable to sustain after  that temperature so even if you eat a bird flu infected bird but yet cook above 80 degree Celsius you will not catch Bird Flu.
