Correct Response: B. Raw meats and seafood can be significant sources of bacteria that cause food contamination. The risk of contaminating other food products can be greatly reduced by employing practices that isolate raw meat and seafood, such as using separate cutting boards and utensils during food preparation. Although storing eggs, milk, and cheese at appropriate temperatures can slow bacterial growth, these foods don't necessarily need to be stored in the coldest parts of the refrigerator in order to reach a safe temperature (A). Leftovers that have been properly refrigerated should be safe to consume for more than two days after they have been refrigerated (C). Cutting boards made of many materials, including porous wood, may be safely used to prepare food (D); to avoid cross-contaminating food via a cutting board, it is more important that the boards be properly sanitized after use and that cutting boards used with raw meats and seafood not be used for other food products.
