Which of the following is a potential source of food contamination?

Unsafe food handling practices are a significant potential source of food contamination because they can introduce harmful bacteria, viruses, or chemicals into food. This includes actions such as improper handwashing, cross-contamination between raw and cooked foods, and inadequate cooking or storage temperatures. When food handlers do not follow safety protocols, it increases the risk of foodborne illnesses, which can have serious health consequences for consumers.

In contrast, proper storage conditions ensure that food is kept at safe temperatures and in a manner that prevents spoilage and contamination. Regular employee training promotes awareness and adherence to food safety practices, reducing the likelihood of errors. Thorough cleaning schedules help maintain a sanitary environment, effectively minimizing the risk of contamination. Each of these factors contributes positively to food safety, highlighting the critical importance of ensuring that food handling practices are safe and compliant with health regulations.
