Quarterly Mortality Reports |
The Louisiana
Department of Wildlife and Fisheries and the U.S. Fish and Wildlife
Service received reports of sick and dead waterfowl in corn fields
and adjacent flooded rice fields in several northeast/east central
Louisiana parishes from November 1998 through late February 1999.
Estimated losses exceeded 10,000 birds; the primary species affected
were snow (and blue) geese. An estimated 100 waterfowl of other
species were affected including Ross' and white-fronted geese and
mallards. Waterfowl were observed feeding in corn fields that had
not been harvested due to high levels of aflatoxin; some fields
had been disced and the corn knocked down in others. Freshly dead
and euthanized geese were sent to the National Wildlife Health Center
and Southeastern Cooperative Wildlife Disease Study for examination.
At necropsy, lesions characteristic of aflatoxicosis were observed
in most geese which included hemorrhagic hepatocellular necrosis
and biliary duct hyperplasia and proliferation. Some geese had degenerative
lesions in other organs including the spleen, pancreas, lungs and
kidneys. Aflatoxin B1 and B2 were detected in stomach contents from
one snow goose at the NWHC. Corn collected from fields where the
geese had been feeding and where mortality occurred contained levels
of aflatoxin as high as 8,200 ppb; far exceeding FDA acceptable
levels of <100 ppb for poultry. (source: NWHC and SCWDS reports)
The first reported
occurrence of duck plague in Arkansas has been diagnosed in waterfowl
submitted to the NWHC by natural resource managers at Little Rock
Air Force Base. Fifteen Muscovy ducks, two mallards, and one Pekin
duck were found dead on the base lake between April 28, and May
10, 1999. DVE was isolated from one Muscovy and one mallard submitted
to the NWHC. Approximately 100 ducks including mallards, mallard
hybrids, Pekin ducks, Muscovy ducks, and wood ducks remained at
the lake after the mortality event. Approximately 30 Canada geese
also frequent the lake on a daily basis.

Branch Chief at 608-270-2420.
