Cross-contamination in the commercial kitchen involves the transfer of harmful microorganisms from one surface or substance to another. Cross-contamination can adversely affect any commercial kitchen, so it is important to take steps to avoid it: make sure to store and prepare foods separately, maintain proper personal hygiene, and correctly clean and sanitize kitchen equipment and supplies. Implementing these behaviors ensures a safer and more sanitary restaurant environment.
Store and prepare foods separately
- Store and refrigerate raw foods separately from ready-to-eat foods.
- Keep raw meats in well-sealed containers.
- Store raw foods on shelves below ready-to-eat foods to minimize contamination.
- Prepare foods on clean, separate surfaces to minimize the spread of germs.
- Utilize clean cutting boards as safe surfaces for preparing foods.
- If possible, designate individual cutting boards for different types of foods.
Maintain proper personal hygiene
Wash hands properly
- Ensure that hands are washed properly before touching food in any way.

Clean between jobs

- Sanitization provides an extra defense against the transfer of germs and allergens.
- Mix 1 capful of unscented bleach per one gallon of water to create a sanitizing agent for most all supplies, equipment, utensils and surfaces.
