Keep ingredients from sharing unwanted passengers
Cross-contamination happens when harmful germs are moved from one place to another. You cannot track them by color or smell, but you can plan the route of a food, tool or hand and interrupt that route.
Put the habit into practice.
Sort by what happens next
Ready-to-eat food will be eaten without another cooking step: think washed salad leaves or a sandwich. Raw meat, poultry, seafood, eggs and raw flour need particular care. Their presence on the same counter is a reason to organize separate work areas and equipment, not to conduct a contamination experiment.
Give tools clear jobs
Use a board and utensils for raw meat, poultry or seafood that are separate from those used for ready-to-eat ingredients. Keep a clean plate ready for cooked food. A label or color can help identify a tool, but its actual use and cleaning matter more than its color.
Pause at the handoff
After handling a raw ingredient, stop before touching a spice jar, tap, refrigerator handle or notebook. Wash hands and clean the equipment that was used. If a surface has been contaminated by raw meat, poultry or their juices, follow the cleaning-and-sanitizing rule. Gloves do not remove the need for handwashing or task changes.
Contain drips during storage
Place raw meat, poultry and seafood in sealed, leakproof containers so juices cannot reach ready-to-eat food. Keep ingredients separate during shopping and unpacking too. An adult manages a leaking package and cleans the affected area; learners can help by identifying the clean route for other foods.
Avoid spreading contamination with water
Rinsing raw poultry or other raw animal foods is not a safety step and can splash germs onto nearby surfaces. Use the no-washing rule for those foods. Produce follows a different rule: rinse it under running water before cutting. Do not turn this distinction into a real raw-food demonstration with children.
Guidance to keep handy
Wash hands with soap and water
Scrub hands with soap and running water for at least 20 seconds, including backs, between fingers and under nails. Rinse and dry with a clean towel.
Before, during and after food preparation; before eating; and after contamination-prone tasks.

Clean before sanitizing
Clean surfaces and utensils with appropriate soap or detergent and water. After cleaning a surface contaminated by raw meat, poultry or their juices, sanitize with a product suitable for that food-contact surface, following every label direction.
An adult selects and uses cleaning products. Product-specific dilution, wet contact time, rinsing, ventilation, protective equipment and disposal directions control; no universal homemade mixture is supplied.

Keep raw foods and ready-to-eat foods separate
Use separate boards and utensils for raw meat, poultry and seafood and for foods eaten without further cooking. Keep raw foods and their juices in sealed, leakproof containers away from ready-to-eat food.
Wash hands and thoroughly clean used equipment at task changes. Raw eggs and raw flour also require separation from ready-to-eat foods.

Do not wash raw animal foods
Do not wash raw meat, poultry, seafood or eggs as a food-safety step; splashes can spread germs around the kitchen.
Home preparation. This is different from rinsing produce.

At the kitchen table
A situation to think through.
An adult has just prepared raw chicken. The same board is suggested for cucumber that will go straight into a salad. The cucumber needs a separate clean board and utensils; wiping away visible moisture does not complete a safe transition.
Which plan prevents the raw-chicken board from becoming the salad board?
Keep these habits handy.
- Use separate boards and utensils for raw meat, poultry and seafood and for foods eaten without further cooking. Keep raw foods and their juices in sealed, leakproof containers away from ready-to-eat food.
- Wash hands at the transition to a new task.
- Clean surfaces and utensils with appropriate soap or detergent and water. After cleaning a surface contaminated by raw meat, poultry or their juices, sanitize with a product suitable for that food-contact surface, following every label direction.
- Do not wash raw meat, poultry, seafood or eggs as a food-safety step; splashes can spread germs around the kitchen.
- Keep investigation samples apart from food being served.

For parents & educators
The adult’s part
Use clean empty packages or drawings for this lesson. An adult handles raw animal ingredients in real meal preparation and any cleanup they require. Explain that experimental samples never join a family meal.
Talk about it
- What surfaces might be touched between the raw-food job and the salad job?
- Why should cooked food have a clean plate?
- How could labels help a group keep track of tools?
Make room for different learners
Trace imaginary paths on paper between an ingredient, hand, tool and plate. Do not use glitter, raw meat or flour as a spreadable germ substitute around real food.

- CDC: Handwashing as a Healthy Habit in the Kitchen ↗
Wash during task transitions, including after handling uncooked animal foods or flour, garbage, pets, and cleaning chemicals.
- CDC: When and How to Clean and Disinfect Your Home ↗
Cleaning removes dirt and germs; sanitizing follows cleaning when needed. Select an appropriate product and follow its label, including contact time and precautions.

Raw flour and raw dough may contain harmful bacteria; do not taste or use raw dough for children’s crafts. Home flour heat treatment is not a reliable safety step.
