Bệnh do Thực phẩmCâu 31 / 320
A food handler at a seafood counter must understand that paralytic shellfish poisoning (PSP) toxins in mollusks like clams and mussels:
a.Cause an immediate skin rash only
b.Are not destroyed by cooking or freezing, so shellfish must come from approved sources
c.Only affect the person if eaten raw
d.Are destroyed by cooking to 145°F
Giải thích
Shellfish toxins such as those causing paralytic shellfish poisoning are naturally occurring, heat-stable, and not destroyed by cooking or freezing, so the only control is buying shellfish from approved, reputable suppliers with proper tags. Cooking to 145°F will not neutralize the toxin, and PSP causes neurological symptoms, not just a rash.
