The storage, preparation and cooking of food must be done in a "clean environment": 

• Clean your refrigerator regularly (once or twice a month)
• Wash your utensils and dishes carefully:

- either by hand with hot water and liquid dish detergent (and then dry them with a clean towel)

- or in the dishwasher with the temperature set to 60°

• Keep your work spaces clean.
• Wash your hands before cooking.
• Prepare small amounts at meals to avoid leftovers and cook all foods thoroughly.
• Store fresh or already cooked foods in the refrigerator.
• Eat leftovers, use up the baby food in jars and opened packages within 48 hours of storing them in the refrigerator.
• Cook frozen foods directly without defrosting them first.
• Never refreeze food that has already been thawed.
• Check product expiration dates.
• When shopping, wrap up fresh foods and then put them in an insulated bag to avoid breaking the cold chain.
