Are waterfowl and migratory birds at risk of spreading Newcastle disease?
Yes, cormorants and pelicans were identified with Newcastle disease in 1992 in Minnesota, South Dakota, Michigan and Canada. One South Dakota poultry site and two North Dakota poultry sites were affected. This episode of Newcastle Disease was not the same strain of END that occurred in California in 1998 and now in 2003, or that occurred in Mexico in 2000.
