How soon do symptoms typically onset after exposure to paralytic shellfish poisoning (PSP)?

The onset of symptoms for paralytic shellfish poisoning (PSP) is characterized by a rapid response following exposure, typically occurring around 30 minutes after consumption of contaminated shellfish. This relatively quick onset is a critical aspect of PSP, as it underscores the urgent nature of the condition and the importance of immediate medical attention following the consumption of potentially toxic seafood. The symptoms can include numbness, tingling, and in more severe cases, respiratory failure. Recognizing the rapid onset allows for better preparedness and response in situations where PSP is suspected, highlighting the essential need for knowledge regarding safe seafood practices.
