Oyster poisoning, also known as shellfish poisoning, can result from consuming oysters contaminated with harmful bacteria or toxins produced by algae.
Symptoms and severity vary depending on the cause, but can include gastrointestinal issues like diarrhea and vomiting, or neurological symptoms like tingling, numbness, and even paralysis.
Some severe cases, like those caused by Vibrio vulnificus, can be life-threatening, requiring intensive care and potentially leading to limb amputation or death, according to the CDC.
Types of Oyster Poisoning and Symptoms:
Vibriosis:
Caused by Vibrio bacteria, leading to diarrhea, vomiting, and potentially severe illness, especially in those with weakened immune systems or chronic liver disease, says the CDC.
Paralytic Shellfish Poisoning (PSP):
Caused by saxitoxins produced by algae, leading to tingling, numbness, paralysis, and potentially respiratory distress.
Neurotoxic Shellfish Poisoning (NSP):
Caused by brevetoxins from algae, resulting in tingling, numbness, dizziness, and gastrointestinal issues.
Diarrhetic Shellfish Poisoning (DSP):
Caused by toxins, leading to nausea, vomiting, abdominal pain, and diarrhea.
Amnesic Shellfish Poisoning (ASP):
Caused by domoic acid from algae, potentially leading to short-term memory loss.
Prevention:
  • Cook shellfish thoroughly: Cooking can kill bacteria and some toxins, but not all.
  • Avoid raw or undercooked shellfish: Especially if you have a weakened immune system or liver disease.
  • Be aware of red tide warnings: Red tide blooms can contaminate shellfish with toxins.
  • Choose shellfish from approved sources: Ensure they are harvested from areas with proper monitoring and regulations, notes the King County (.gov).
