When is it acceptable to use the same cutting board for raw meat and vegetables?

The practice of never using the same cutting board for raw meat and vegetables is grounded in the principle of preventing cross-contamination. Raw meat can carry harmful bacteria such as Salmonella and E. coli, which can transfer to vegetables if the same cutting board is used without proper sanitization in between uses. Cross-contamination can lead to foodborne illnesses, making it crucial to maintain strict separation between raw meat and ready-to-eat foods like vegetables.

This health standard emphasizes that using different cutting boards for these items—one specifically designated for raw meat and another for vegetables—significantly reduces the risk of spreading bacteria. Proper food safety protocols, including the use of separate utensils and equipment, are essential in both home kitchens and commercial settings like McDonald's to ensure food safety and protect customers' health.

Other options suggest various scenarios under which it might be acceptable to use the same board, but each fails to take into consideration the critical step of ensuring no harmful bacteria could be transferred.
