Consumption of stew containing which mollusk has been associated with development of cardiac glycoside toxicity?
Ingestion of stew containing Helix Pomatia (the burgundy snail) has been associated with secondary exposure to cardiac glycosides from Nerium Oleander. According to the cited reference, after consumption of the stew, two patients exhibited signs and symptoms of cardiac glycoside toxicity and had measurable cardiac glycoside concentrations in blood and urine. Analysis of disrupted tissue from snails collected in the same area as those that were ingested revealed measurable concentrations of cardiac glycoside.
