What is a common symptom associated with toxin exposure from seafood?

Tingling in extremities is actually a common symptom associated with certain types of seafood poisonings, particularly those caused by toxins produced by harmful algal blooms, such as those leading to paralytic shellfish poisoning (PSP) or other neurotoxic shellfish poisonings. These toxins can affect the nervous system and lead to sensations like tingling, numbness, or even paralysis in severe cases.

Recognizing this symptom is important for food safety professionals and those handling seafood, as it can indicate an issue related to the consumption of contaminated shellfish. Understanding the neurological effects of these toxins helps in identifying and responding appropriately to seafood-related illnesses.

While nausea, fever, and coughing may be general symptoms of various illnesses, they are not specifically strong indicators of seafood toxin exposure. Instead, the tingling sensation uniquely highlights a potential neurotoxic reaction that can occur from certain seafood, making it a key symptom for monitoring and addressing foodborne illnesses linked to seafood.
