HUMAN NUTRITION

Detailed explanation-1: -Microbes can be transferred from one food to another by using the same knife, cutting board or other utensil without washing the surface or utensil in between uses. A food that is fully cooked can become re-contaminated if it touches other raw foods or drippings from raw foods that contain pathogens.

Detailed explanation-2: -Researchers also grated produce, like carrots, to see how easily the pathogens spread to graters. They found that both knives and graters can cause additional cross-contamination in the kitchen and that the pathogens were spread from produce to produce if the utensils weren’t washed.

Detailed explanation-3: -An easy way to prevent cross-contamination is to use different chopping boards and different knives for raw and ready-to-eat food. Try using one colour for chopping boards and knives used with raw food and another colour for those used with ready-to-eat food.

Detailed explanation-4: -Touching raw meats then handling vegetables or other ready-to-eat foods without washing hands between tasks. Using a food soiled apron or towel to wipe your hands between handling different foods. Failing to change gloves between handling different foods.
