In February 2004, a highly pathogenic avian influenza (HPAI) virus outbreak was reported in a flock of broiler chickens in Gonzales County, Texas. Subsequent epidemiologic investigations identified infected birds in 2 live-bird markets in the area of Houston. These markers had received birds from the index flock or birds that had been transported by the index flock manager. All infected premises were depopulated, cleaned and disinfected. Disease surveillance standards were established to assess the potential for spread of the virus from the index flock. Surveillance testing in commercial and non-commercial poultry operations revealed no area spread of the virus from the index flock. The effective control of this outbreak was attributed to the preexisting plan for surveillance and control developed by the different public and animal health agencies in Texas. This article provides an overview of the AI outbreak in Texas in 2004 and the measures taken by the USDA and local animal and public health agencies to control the disease.
