Starbucks Food Safety Practice Exam

What is required in all culinary and pot/dish washing sinks?

1. Filtration systems

2. Air-breaks

3. Drain screens

4. Waste baskets

The correct answer is: Air-breaks

An air-break is required in all culinary and pot/dish washing sinks to prevent backflow contamination. This is a critical safety measure that ensures that wastewater cannot flow back into the clean water supply. It functions by creating a physical gap between the sink’s drainage system and the sewer system. By doing so, it minimizes the risk of contaminants entering the potable water system, thereby safeguarding food safety and public health. The other options, while they may contribute to overall kitchen cleanliness or organization, do not specifically address the critical need for backflow prevention in culinary and dishwashing operations. For instance, filtration systems are useful for providing clean water but do not prevent contamination through backflow. Drain screens help catch food debris but are not a preventive measure against water contamination. Waste baskets support kitchen hygiene but are not relevant to the water safety standards aimed at protecting against backflow risks.
