Cross-Contamination Happens Before You Ever See It
The riskiest moment in a kitchen is often invisible: a cutting board, knife, or hand that touched raw meat then touches something that won't be cooked again, like salad greens or a finished dish, transferring bacteria directly onto food no heat will kill afterward. Using a separate board for raw proteins (or washing thoroughly with hot soapy water between uses), and always working with ready-to-eat ingredients before raw meat rather than after, closes the gap.
