Domoic acid and saxitoxin in seabirds from California and Rhode Island 2015-2017

As harmful algal blooms (HABs) increase in magnitude and duration worldwide, they are becoming an expanding threat to marine wildlife. Over the past decade, domoic acid (DA) and saxitoxin (STX) have been increasingly problematic bicoastally in the United States. We investigated pooled seabird mortality data from opportunistic sampling events between 2007-2018, across three states, to examine the patterns and role of DA and STX in seabird mortality events from the continental United States. Patterns in DA and STX levels and affected tissue type were reviewed, and two specific accounts of localized and pervasive event types were examined. There has been increased toxin detection with expanded tissue testing during...

Results of algal toxin testing from wildlife mortality submissions to the National Wildlife Health Center

This data set is composed of all animals received as a diagnostic submission to the USGS National Wildlife Health Center for which algal toxin testing was performed from November 1998 to January 2018. Birds with a histologic diagnosis of avian vacuolar myelinopathy, a disease caused by the algal toxin aetokthonotoxin, are also included. Algal toxins tested for include brevetoxin, cylindrospermopsin, domoic acid, microcystin, and saxitoxin. Case-accession number, species, state collected, month and year collected, and detection or non-detection of the algal toxin is reported.

USGS National Wildlife Health Center necropsy results to determine cause of illness/death for seabirds collected in Alaska from January 1, 2017 through December 31, 2021

Summary of Bering and Chukchi Seas seabird necropsies, 2017-2021. More than 14,000 dead seabirds were reported and a total of 117 carcasses were examined. 92 cases had emaciation identified as the Cause Of Death (COD), seven cases where COD was undetermined, and 17 cases where COD was determined as "Other", which included predation, trauma, encephalitis, peritonitis, and bacterial infection. Low Pathogenic Avian Influenza (n=4) and saxitoxin (n=15) were also detected; however, the virus and biotoxin were not determined to be the COD except for one case in 2020 where saxitoxin toxicosis was suspected.
