HOW BIRD FLU CURRENTLY SPREADS
The bird flu virus has been tracked to various places by fecal matter being transported on shoes, farming equipment, egg cartons, truck tires. It can live up to 3 months in bird feces.
The adoption of certain new farming techniques in South East Asia increases the odds that another such strain will soon emerge. Pigs, ducks and chickens live side by side on many developing world farms, especially those engaged in fish farming. Widely promoted as an energy efficient way to produce high yields of protein foods, fish farming is done by feeding poultry feces to pigs and fertilizing fish ponds where ducks also swim and drink with fresh pig manure.
These are filthy, inhumane conditions that most of these chickens are raised in and and the disregard to adhere to official health regulations that has has made South East Asia the number one hot spot for Avian Flu epidemics and pandemics.
However, in North America, due to our poultry farming practices we have also had birds affected in recent years with a lower strain of the virus.
Packing 25,000 to 50,000 chickens into a barn, a common practice in big poultry operations in Canada, the United States and elsewhere, creates ideal conditions for breeding viruses, adds Debra Probert, executive director of the Vancouver Humane Society. "We're taking a big risk with our own health raising animals under those conditions."
