Bird flu Q&A: Answers for livestock producers

"Do I report dead wild birds?
A dead bird in your yard or field should not cause undue concern. However, because birds may die from a variety of causes, don't touch the bird with bare hands. Place a plastic bag over your hand and pick up the bird, enclosing it in the bag and disposing of it in the garbage. Then wash your hands thoroughly. If you see a die-off of many birds, notify your local health officials. Samples then can be collected to determine if the birds died from avian influenza or some other cause."
