What do I need to know about Avian Flu?
What is Avian Influenza?
Just like humans, birds can get the flu. “Avian influenza,” “avian flu” or simply “bird flu” is a disease that affects birds, including poultry like chickens, turkeys and ducks. It is caused by a virus that is passed from bird to bird through their saliva, nasal secretions and/or feces. Other susceptible birds pick up the virus by directly touching the infected bird’s fluids or by touching a surface that has been contaminated by the fluids. There are two classifications of bird flu – low pathogenic avian influenza (LPAI) and highly pathogenic avian influenza (HPAI). Birds who contract LPAI sometimes don’t show any symptoms or show mild ones, like ruffled feathers or lower egg production. Birds with HPAI suffer more severe symptoms similar to symptoms of human flu like lack of energy or appetite, lack of coordination, coughing, sneezing or nasal secretions, and can cause rapid death.
Can people catch avian influenza?
The risk of humans contracting avian flu is very low, according to the Centers for Disease Control and Prevention (CDC). Scientists say bird flu is not easily transmitted from birds to humans.
What is the status of HPAI incidents in the United States?
From mid-December 2014 to June 2015, there were several highly pathogenic avian influenza (H5) incidents along the Pacific, Central and Mississippi Flyways on commercial turkey and egg laying hen farms, largely in Minnesota and Iowa. In January 2016, there was one HPAI positive test on a commercial turkey farm in Indiana. That incident was handled quickly and the virus appears to have been eradicated. There have been no positive tests since on any farms in the U.S.
What are chicken producers doing to prevent avian influenza?
Avian flu is a serious issue that chicken farmers closely monitor together with the USDA and poultry industry. The U.S. has the most robust monitoring and surveillance programs in the world – and detailed plans in place to control spreading among flocks and eliminate the virus completely. All U.S. flocks are tested year-round for avian influenza, and if a single bird in a flock were to test positive for avian flu, then none of those birds would be allowed to enter the food supply.
To date, commercial broiler flocks –chickens which are raised for meat – have not experienced any HPAI infections. Farmers, the USDA and the poultry industry as a whole continue to monitor for the virus closely, and have increased surveillance and biosecurity measures to keep flocks protected. Good biosecurity practices on the farm are key to preventing avian influenza from infecting the birds.

What happens if there is an outbreak of avian Influenza on a chicken farm?
In the event of an outbreak, the poultry industry has strict procedures in line with state and federal organizations to identify the problem and reduce the spread of the disease.
When avian flu is detected, the following five-step response plan is carried out:
First, the farmer ensures that the affected flock stays put in one area, along with any equipment that has been near the birds.
The affected flock is then quickly and humanely euthanized.
At the same time, both wild and domestic birds in a broad surrounding “control” area are tested and monitored for avian influenza.
The farm where the flock was housed is then thoroughly disinfected to ensure any traces of the virus is killed.
Last, the entire poultry farm is carefully tested for 21 days to confirm it is free of bird flu before allowing a new flock of birds to arrive.
No birds from avian flu-affected flocks are ever allowed to enter the food chain.
What can I do at home to make sure my chicken is safe from avian influenza?
Avian flu is not a foodborne illness, which means you can’t contract it from eating poultry that has been cooked properly. And in the event a flock does test positive, it will not enter the food chain. Get safe food handling tips at Chicken Roost.
