A recent article posted on agweb.com reminds poultry producers that as far as the avian flu is concerned, we're not in the clear yet. Poultry and egg farms across 15 states were affected by avian influenza this spring. About 48 million birds either passed from the disease or were euthanized to prevent the spread. Agriculture officials caution that the wild bird migrations in the fall could bring the disease back. It is also speculated that the disease could be mutated by then.
