Final answer:
The prevention measures for paralytic shellfish poisoning are avoid consuming shellfish from contaminated areas, cook shellfish thoroughly before consuming and avoid consuming shellfish during red tide events, So option 4 is correct.
Step-by-step explanation:
The prevention measures for paralytic shellfish poisoning include avoiding consuming shellfish from contaminated areas, not eating shellfish during red tide events, and thoroughly cooking shellfish before consuming.
However, cooking may not always destroy the toxins present in contaminated shellfish.
It is crucial to follow public health warnings and regulation measures such as those implemented by the Division of Marine Fisheries, which monitor toxin levels and may enforce harvesting bans to protect public health.
Hence, to prevent paralytic shellfish poisoning, refrain from consuming shellfish from contaminated areas or during red tides. Ensure thorough cooking, although it may not eliminate all toxins. Option 4 is the correct choice.
