Cross-contamination is the primary cause of foodborne illness outbreaks because it involves the transfer of harmful bacteria from raw food to ready-to-eat food. This can occur through contact with contaminated surfaces, utensils, or hands. By allowing these bacteria to transfer onto food that will not undergo further cooking or processing, there is a high risk of causing illness when consumed. Proper hygiene and cooking techniques are important factors in food safety, but cross-contamination poses the most significant risk in causing foodborne illnesses.
