Question

question 7 which of the of the following resulted in beach closures in alaska? scombroid poisoning saxotoxin aflatoxin ciguatoxin

Explanation:

Saxotoxin is a neurotoxin produced by certain dinoflagellates. When there is a bloom of these dinoflagellates (a red - tide event), it can contaminate shellfish. In Alaska, such events have led to beach closures due to the risk of saxitoxin poisoning from consuming contaminated shellfish.
Scombroid poisoning is usually associated with mishandled fish (like tuna, mackerel) and is not typically linked to beach closures. Aflatoxin is a mycotoxin (produced by fungi) usually found in crops like peanuts, corn, etc. Ciguatoxin is associated with tropical reef fish and is not a common cause of beach closures in Alaska.

Answer:

Saxotoxin
