Poultry Health

Avian Influenza

Avian Influenza (AI) is a flu virus that may cause illness in domestic poultry, fowl and birds. Migratory waterfowl are a natural reservoir for this disease.

There are many strains of the AI virus. Based on the severity of illness caused by the virus, these strains are put into two classifications, low pathogenic (LPAI) and highly pathogenic (HPAI). LPAI causes only minor illness and occurs naturally in migratory waterfowl. HPAI spreads rapidly and has a high death rate in birds.

The TAHC advises poultry owners to practice strong biosecurity and remain vigilant in examining the health of their birds. If your birds exhibit unusual death loss or signs of illness, or you observe large scale sickness and mortality of wild birds, call your private veterinarian or the TAHC immediately at 1-800-550-8242.


Exotic Newcastle Disease

Exotic Newcastle Disease (END) is a contagious and fatal viral disease affecting most species of birds. Also known as Velogenic Viscerotropic Newcastle Disease (VVND), END is a foreign animal disease in the U.S. and is considered one of the most infectious diseases of birds and poultry. END can infect and cause death even in vaccinated poultry. END is a reportable disease to the Texas Animal Health Commission.


Infectious Laryngotracheitis

Infectious Laryngotracheitis (ILT) is an acute, highly infectious, respiratory disease in poultry caused by a herpesvirus. ILT is a reportable disease to the Texas Animal Health Commission.


Pullorum Typhoid

Pullorum Typhoid (PT) are septicaemic diseases, primarily of chickens and turkeys, caused by bacteria. Fowl typhoid should not be confused with typhoid fever in humans, which is caused by a different organism. PT is a reportable disease to the Texas Animal Health Commission.


Poultry & Fowl Registration

The TAHC registers domestic and exotic fowl sellers, distributors, or transporters who do not participate in disease surveillance programs recognized by the TAHC. Registrations are good for one year from the date of issuance.
