What is a symptom of contamination in food?

The presence of pests or spills is a clear indicator of contamination in food. Pests, such as insects or rodents, can carry harmful bacteria and pathogens that lead to foodborne illnesses. Their presence suggests that the food has been exposed to unsanitary conditions. Similarly, spills can introduce contaminants from the environment, including dirt, chemicals, or organic matter, which can compromise food safety. Identifying these visible signs is essential for maintaining hygiene and preventing foodborne illnesses in food handling practices.

While factors like a significant temperature drop or a change in color may suggest potential issues with food quality or safety, they are not definitive symptoms of contamination. Freshness, on the other hand, is related to the quality of food rather than a symptom of contamination. Understanding and recognizing visible signs of contamination, such as pests and spills, is vital for food handlers to ensure a safe food environment.
