(HealthDay News) -- Reusable grocery totes may be friendly for the environment, but they can also befriend harmful bacteria.

The Academy of Nutrition and Dietetics suggests how to keep grocery totes clean:

• Regularly wash grocery totes either by hand (use hot, soapy water) or in the washing machine.
• Bag separately in plastic any fish, poultry or meat before placing them in a tote. Be sure to separate these products from prepared or packaged foods.
• Carefully clean any kitchen areas (such as a counter) where you place totes while unpacking.
• Don't leave totes in the trunk of your car; store them in a cool, dry place.
