Explanation:
Cross-contamination refers to the transfer of harmful microorganisms or substances from one food service to another. This can occur when pathogens, allergens, or chemicals are transferred from contaminated foods or surfaces to other foods. For example, if a cutting board used to prepare raw chicken is not properly cleaned before being used to chop vegetables, it can result in the transfer of bacteria from the chicken to the vegetables.
Pathogens, such as bacteria, viruses, and parasites, can cause foodborne illnesses if consumed. Allergens, on the other hand, can trigger allergic reactions in individuals with allergies. Chemicals, including agrochemicals and environmental contaminants, can also contaminate food and have long-term health effects.
