HUMAN NUTRITION

Detailed explanation-1: -A food that is fully cooked can become re-contaminated if it touches other raw foods or drippings from raw foods that contain pathogens. Cross-contamination is the physical movement or transfer of harmful bacteria from one person, object or place to another.

Detailed explanation-2: -Cross-contamination is what happens when bacteria or other microorganisms are unintentionally transferred from one object to another. The most common example is the transfer of bacteria between raw and cooked food. This is thought to be the cause of most foodborne infections.

Detailed explanation-3: -Cross-contamination can happen in a number of ways: Direct cross-contamination-allowing raw food that has food poisoning bacteria on it to touch cooked or ready to eat food. Indirect cross-contamination-where something helps the organisms move from one place to another. We call these ‘vehicles’ of contamination.

Detailed explanation-4: -Cross-contamination occurs when microorganisms (bacteria, parasites, viruses)are transferred from a food where they occur naturally to one where they do not naturally occur. This is dangerous because unsuspected foods are not necessarily prepared in a manner to prevent the survival of microorganisms from other sources.

Detailed explanation-5: -It usually occurs from raw foods to ready-to-eat products (RTE) or between products that contain allergens and allergen-free products. Cross-contamination can cause food poisoning when harmful bacteria are transferred to RTE products that do not undergo further processing to eliminate bacteria.
