Example of causative food
Bivalves that have not been sufficiently heated, various foods cooked and served through hands
Features
It accumulates in bivalves during the low sea temperature season and causes food poisoning. Because it is highly infectious and excreted from the stool of infected people, inadequate hand washing after defecation can contaminate food and the surrounding environment and cause secondary infection.
Symptoms
After 24 to 48 hours after eating, nausea, vomiting, diarrhea, abdominal pain, fever, etc. develop.
Preventive measures
・Bivalves such as oysters should be heated sufficiently to the center.
・Wash your hands thoroughly with soap after using the toilet, before cooking, and before eating, as the infection may not cause symptoms.
・Avoid cooking when you feel unwell, such as diarrhea or vomiting.
・Alcohol is less effective for disinfecting norovirus, so use sodium hypochlorite.
