Foodborne Illness第 12 / 240 题
A sushi chef in NYC prepares raw fish dishes. Which parasite is a specific concern in raw or undercooked marine fish, and what control addresses it?
a.Giardia; controlled by cooking rice thoroughly
b.Cyclospora; controlled by washing hands
c.Anisakis (roundworm); controlled by freezing fish to required time-temperature parameters before raw service
d.Cryptosporidium; controlled by adding vinegar to the rice
解析
Anisakis is a roundworm found in marine fish that can cause abdominal illness when fish is eaten raw or undercooked. The control is freezing the fish to required parameters, for example -4°F for the specified time, before serving it raw, which kills the parasite. Neither acidifying sushi rice nor handwashing destroys parasites already in the fish flesh.
