Pufferfish poisoning can occur among those who eat pufferfish. The fish is served as an Asian delicacy in some forms of sashimi and sushi. The poison present in the fish is tetrodotoxin which is one of the most toxic poisons in nature.
The chef preparing dishes that include pufferfish are specially trained to slice the meat in a specific manner since it might contain the toxin.
What are the signs?
The symptoms typically manifest within 10-45 minutes after ingesting the pufferfish and starts with tingling and numbness around the mouth, nausea, salivation and vomiting.
The symptoms might later progress to paralysis, respiratory failure, loss of consciousness and even death.
Management of pufferfish poisoning
- If the individual is suspected with pufferfish poisoning, vomiting is generally induced if he/she is alert and awake and consumed the fish within 3 hours.
- The individual can end up paralyzed. Artificial respiration can keep the individual alive until medical care is provided in the emergency department.
- If vomiting occurs, quickly turn the individual onto his/her side.
- In some cases, CPR should be performed if needed along with breathing assistance.
Potential complications
The possible complications that might arise from pufferfish poisoning typically include:
