Northwest Iowa Dairy Outlooks

A local discussion of current science and issues concerning dairying in northwest iowa

Tag Archives: poultry

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H7 avian influenza (HPAI) of North American wild bird lineage in a commercial chicken breeder flock in Lincoln County, Tennessee. This is the first confirmed case of HPAI in commercial poultry in the United States this year. The flock of 73,500 is located within the Mississippi flyway.

Samples from the affected flock, which experienced increased mortality, were tested and confirmed at the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa

State officials quarantined the affected premises and birds on the property have been depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 ˚F kills bacteria and viruses.

The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.These virus strains can travel in wild birds without them appearing sick. People should avoid contact with sick/dead poultry or wildlife. If contact occurs, wash your hands with soap and water and change clothing before having any contact with healthy domestic poultry and birds.

All bird owners, whether commercial producers or backyard enthusiasts, should continue to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through USDA’s toll-free number at 1-866-536-7593.

While no known links to dairy cattle are know, this is a good time for dairymen to review their biosecurity plans. In-depth information can be found at:

Avian influenza (AI) is caused by an influenza type A virus which can infect poultry (such as chickens, turkeys, pheasants, quail, domestic ducks, geese and guinea fowl) and is carried by free flying waterfowl such as ducks, geese and shorebirds. AI viruses are classified by a combination of two groups of proteins: hemagglutinin or “H” proteins, of which there are 16 (H1–H16), and neuraminidase or “N” proteins, of which there are 9 (N1–N9). Many different combinations of “H” and “N” proteins are possible. Each combination is considered a different subtype, and can be further broken down into different strains. AI viruses are further classified by their pathogenicity (low or high)- the ability of a particular virus strain to produce disease in domestic chickens.

U.S. Sen. Pat Roberts, the Republican from Kansas, and chairman of the U.S. Senate Committee on Agriculture Nutrition and Forestry announced last week that the first hearing in the country on the 2018 Farm Bill reauthorization will be Feb. 23 on the Kansas State campus in Manhattan, KS. The time has not be announced.

Beth Doran and Fred M. Hall, Northwest Iowa livestock and dairy specialists will host the live webinar in the basement meeting room at the Sioux County Extension office. No registration is required, but seating will be on a first come basis. The time of the hearing will be announced as soon as it is released.

Roberts says the hearing will feature testimony from a variety of specifically invited agricultural producers. He says lawmakers need clear direction from producers on what is working and what isn’t working in farm country.

The poultry industry has done a lot of disease response planning, but manure disposal may be a missing link for backyard flock owners. Biosecurity procedures, which are designed to keep diseases out of flocks, have become a particularly pressing concern since last year’s avian influenza outbreak killed or forced the depopulation of 48 million birds, mostly in Iowa and Minnesota.
