Cross-contamination is defined as what?

• A. The transfer of bacteria from 1 source to another
• B. The process of cooking food to safe temperatures
• C. The proper disposal of waste
• D. The use of gloves at all times

Answer: (A)

Cross-contamination means the transfer of bacteria from one source to another. In food safety this is the spread of pathogens from raw foods, contaminated surfaces, or hands to foods that will be eaten, especially ready-to-eat items. This is dangerous because microbes can move unseen and still cause illness even if the final food is cooked later. To prevent it, keep raw and cooked foods separate, use different cutting boards and knives for different foods, wash hands frequently, and sanitize work surfaces and utensils after contact with raw ingredients. For example, using the same knife on raw chicken and then on salad without cleaning can transfer bacteria. Cooking to safe temperatures kills bacteria, but it doesn’t stop the transfer from happening, and proper practices like cleaning and separating are essential.
