Avian Flu

There is no such thing as too much biosecurity, as it is always of utmost importance.

Here are five important safety points to remember to keep your farm safe!

1. Avoid contact with migratory waterfowl.
2. Do not allow visitors to your farm. If they must come on farm, they must practice strict biosecurity while they are on farm.
3. Change clothes and shoes before entering poultry houses and before leaving the farm.
4. Have dedicated footwear or shoe covers for each poultry house.
5. At the first sign of increased mortality, anything over ¼ of 1% of house capacity, or severe decrease in water consumption, please contact your company service personnel.
6. Keep all non-essential personnel away from the poultry houses.

Highly Pathogenic Avian Influenza (HPAI) is rapidly spreading across the broiler belt of the United States, with migratory waterfowl as the primary carriers. Alabama is a part of the Mississippi Flyway migration route of these birds, putting one of the state’s most important agricultural commodities at risk: commercial poultry.

The Risks

Domestic fowl have no natural immunity to HPAI, and there is no treatment for the resulting disease. The virus is also extremely virulent and spreads in an enclosed aviary or commercial poultry house like wildfire. The only way to control further spread is to euthanize the entire flock after confirmation of the disease. For the commercial poultry industry, this means the potential loss of millions of birds.

Potential for Economic Losses

The scope of the economic catastrophe resulting from a major HPAI outbreak in Alabama is difficult to grasp. However, when one considers the recent economic impact estimation of $15 billion total from poultry operations in the state, even a small percentage means a lot of dollars lost.

For a contract poultry grower, the loss of an entire flock of birds would be devastating. No grower can withstand the loss of one-fifth of their entire annual revenue and not be put in a dire financial situation. For the average grower in Alabama, the loss of a flock could equate to the loss of $45,000 to $55,000 in revenue. These types of losses are typically not covered by normal farm insurance policies, and often the contract provider has no relief to offer. For every dollar the grower loses, the company loses as much as ten times that amount in cost and potential revenue.

The USDA does have an indemnity program to compensate growers for the destroyed flock, disposal of the carcasses, and cleanup of the infected facilities. However, this amount does not cover all the losses that are incurred by either the grower or the company. For more information, see the USDA publication The HPAI Indemnity and Compensation Process Start to Finish.

Biosecurity Measures Must Be a Priority

During a recent University of Arkansas Agriculture Research and Extension webinar on HPAI for industry professionals, Terry Conger, a poultry health epidemiologist with USDA’s Animal and Plant Health Inspection Service (APHIS), encouraged a lockdown around poultry activities. Conger warned that because of the perpetual risk of HPAI from waterfowl, the only preventive tool growers can rest their hopes on is stringent biosecurity. The bottom line is that every grower in the state must do everything possible to keep HPAI out of their flocks. Because HPAI infection can spread quickly by the movement of contaminated shared equipment, vehicles, service personnel, visitors, and pests including rodents and insects, poultry growers cannot be too stringent in their efforts to protect their flocks.

Every integrator in Alabama has tightened their biosecurity procedures in recent years, but the weakest link is always at the grower level. This is simply because the growers have daily contact with their birds. As HPAI becomes more widespread, biosecurity must become an automatic part of life for those that oversee a commercial or backyard flock.
