Signs developed approximately 48 to 72 hours after accidental access to black oil sunflower seeds.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s002\">\n<jats:title>CLINICAL FINDINGS<\/jats:title>\n<jats:p>3 alpacas died suddenly prior to treatment and were necropsied. One llama survived, and 1 alpaca and 1 llama died after days of medical treatment. All 3 treated animals had systemic inflammatory signs including tachycardia, fever, and hematologic changes. Biochemical anomalies included azotemia, hyperglycemia, hyponatremia, hypochloremia, and hypoalbuminemia. Necropsy identified numerous sunflower seeds in the gastrointestinal tract of all 5 animals that died, with pulmonary congestion (5\/5 animals), mild centrilobular vacuolar hepatic degeneration (4\/5), and erosions of the esophagus (3\/5) and first (3\/5) and third (1\/5) compartments of the forestomach. Renal tubular necrosis was found in the 2 animals that died on day 4 of treatment.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s003\">\n<jats:title>TREATMENT AND OUTCOME<\/jats:title>\n<jats:p>One llama responded successfully to intensive medical management including supplemented IV fluid therapy, oral and partial parenteral nutrition, and administration of antimicrobials, furosemide, and insulin and was clinically normal with plasma biochemical analysis values within reference range 12 weeks later. Vitamin D, oxalates, heavy metals, and mycotoxins were excluded as the cause of clinical signs on the basis of screening of uneaten seeds and tissue samples and gastric content from the treated llama that died.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Inadvertent large volume black oil sunflower seed ingestion resulted in a high mortality rate in camelids. A specific toxic principle was not identified. Feeding this product to camelids is not recommended to avoid the risk of accidental overingestion and subsequent disease.
