Incorrect; the correct answer is C.

Bacteria are common on the surface of raw meat. Although the utensils, like knives and cutting boards, are cleaned after use, the bacteria cannot be removed completely as some of them may remain in the cracks of cutting boards or on the handles of knives. Using the same set of utensils to prepare ready-to-eat (RTE) foods and non-RTE foods will increase the risk of cross contamination.

The most effective way to eliminate cross contamination is to use separate utensils for RTE and non-RTE foods. Two sets of knives and cutting boards should be kept in the kitchen.

If only one set of cutting board and knife is available, you should handle the cooked chicken first and thoroughly clean the cutting board and knife with liquid detergents before handling raw meat. This can prevent cross contamination of cooked foods.
