Virulent Newcastle Disease in Chickens

Being a good bird keeper means protecting them from danger, both seen and unseen.  One of the latest threats to rear its ugly head is Newcastle Disease.  What is it, what can you do about it, and how can you prevent it from harming your birds?  Keep reading to find out.

Newcastle Disease is a highly contagious viral disease.  The virus lives in respiratory discharge and feces of infected birds, and can be spread through direct bird to bird contact, or through contact with contaminated people, feed, or equipment.  While all birds can become infected, chickens are affected most severely and can die from the disease.

Symptoms include swelling around the eyes, swelling that may be purple in color around the wattle and comb, nasal discharge, loss of appetite, and diarrhea.  Birds may exhibit a twisting of the head and neck, and sometimes will die suddenly.

There is no cure for Virulent Newcastle Disease.  That means that prevention is the most important thing you can do to keep your birds safe.  Follow good biosecurity practices.  Wash your hands after coming into contact with birds.  Avoid sharing equipment.  Make sure to disinfect equipment and thoroughly wash clothing.  Any vehicles on the property should have their tires washed upon entry and exit.   Do not bring in any new birds to the flock while there are any active disease outbreaks in your state.  Quarantine any birds on your property that exhibit symptoms.

Humans do not normally become infected with Virulent Newcastle Disease.  In very rare cases, people in extremely close contact with infected birds may experience a mild fever or redness and swelling near the eyes.  Properly cooked meat and eggs from infected birds are safe to eat.
