What is cross-contamination?Show answer
Cross-contamination is the transfer of harmful bacteria from one food (usually raw) to another (often ready-to-eat) by direct contact or through hands, surfaces, boards or utensils. Because raw meat, poultry and seafood often carry bacteria, the most important rule is to keep them, and anything that touches them, away from ready-to-eat foods.
