Centre for Disease Control (BCCDC), and Health Canada to investigate
these illnesses. This investigation is ongoing.
Food contaminated with diarrheal shellfish poisoning (DSP) biotoxin
may not look or smell spoiled. Consumption of food contaminated with
this biotoxin may cause diarrheal shellfish poisoning, a foodborne
illness. Diarrheal shellfish poisoning can cause diarrhea, nausea,
vomiting, abdominal cramps and chills.
The Canadian harvester and distributors are voluntarily recalling the
affected product from the marketplace. The CFIA is monitoring the
effectiveness of the recall.
[Diarrheal shellfish poisoning (DSP), a toxin-associated illness
associated with okadaic acid production in dinoflagellates, which can
be associated with mussels, seems to be the diagnosis here. Diarrhea
is the most commonly reported symptom (92 percent), closely followed
by nausea (80 percent) and vomiting (79 percent), with onset 30
minutes to 12 hours from ingestion. - Mod.LL]
