Understanding Cross-Contamination
Cross-contamination refers to the transfer of harmful bacteria or pathogens from one surface or food to another, leading to foodborne illnesses. In the examples provided:
- When bacteria from raw food is transferred to ready-to-eat food - This occurs commonly in kitchens when raw meat juices come into contact with vegetables or other foods that won't be cooked before consumption.
- When pathogens are transferred from your bare hands to ready-to-eat foods - If hands are not properly washed after handling raw foods, the bacteria can easily spread to food that will not be cooked.
- When raw vegetables from your supplier are prepared before being washed - This puts the ready-to-eat food at risk of contamination from surface dirt or bacteria that might be present on the vegetables.
Therefore, the best answer is All of the above. All these situations exemplify cross-contamination and demonstrate the importance of proper food handling practices in preventing foodborne illness.
