Final answer:
Yellow cutting boards or tongs are used with cooked foods, following the color-coding system used in professional kitchens to prevent cross-contamination according to HACCP guidelines.
Step-by-step explanation:
The color of cutting board or tongs to be used with cooked foods is yellow. In professional kitchens, color-coded kitchen tools are used as part of a food safety management system known as HACCP (Hazard Analysis Critical Control Point).
This system helps to prevent cross-contamination between different types of food. Each color typically represents a different food group, for example, red is for raw meat, blue is for raw fish, green is for fruits and vegetables, and yellow is designated for cooked foods. Therefore, when handling cooked foods, you should use yellow cutting boards and tongs.
