Since norovirus can also come from food contaminated with the virus, you should always practice safe food handling methods:
• Wash fruits and vegetables before preparing or eating
• Cook oysters, which are at risk for contamination from water, and other shellfish thoroughly
• Keep surfaces clean and disinfected
• Avoid cross contamination
• Don’t touch your face while handing food
• If there’s a chance food has been in contact with norovirus, throw it out
• Do not cook or serve food if you’re sick
