Which is a potential outcome of inadequate cleaning and sanitizing?

Inadequate cleaning and sanitizing can lead to contaminated food sources. This occurs because surfaces, utensils, and equipment that are not properly cleaned and sanitized may harbor harmful bacteria, viruses, and other pathogens. These harmful microorganisms can then transfer to food items, leading to foodborne illnesses. This is a critical concern in food safety, as it can result in significant health risks for customers and legal implications for food service establishments. Ensuring that all food contact surfaces are properly cleaned and sanitized is essential to maintain food safety and prevent contamination.

The other options suggest outcomes that do not align with the consequences of poor hygiene practices. Improved food flavor, decreased food costs, and improved customer satisfaction are all positive results that would not arise from inadequate cleaning and sanitizing, as those practices are foundational for maintaining quality and safety in food service.
