If work surfaces and utensils are not properly cleaned and sanitized, what can happen to food?

When work surfaces and utensils are not properly cleaned and sanitized, harmful bacteria, viruses, or other pathogens can contaminate food. This contamination can lead to foodborne illnesses, making the food unsafe for consumption. Ensuring that surfaces and utensils are clean and sanitized is critical in preventing cross-contamination and reducing the risk of foodborne diseases. The other options suggest positive outcomes related to food quality or safety, which are not achievable without proper sanitation practices. For instance, unsanitized surfaces will not contribute to food lasting longer, retaining flavor, or being more nutritious; rather, they pose significant health risks.
