Food Manager Practice Exam

Which of the following is NOT an approved chemical sanitizer?

1. Chlorine

2. Iodine

3. Quaternary Ammonium

4. Hydrochloric Acid

The correct answer is: Hydrochloric Acid

Hydrochloric acid is not an approved chemical sanitizer for food contact surfaces. Unlike chlorine, iodine, and quaternary ammonium compounds, which are widely recognized and validated for their effectiveness in sanitizing and destroying pathogens on surfaces in food establishments, hydrochloric acid is primarily used as an industrial cleaner or descaler. Its properties can be corrosive and harmful, making it unsuitable for sanitization in food service. Chlorine is commonly used for sanitizing food surfaces and utensils due to its strong oxidizing properties, which effectively kill bacteria, viruses, and fungi. Iodine is another approved sanitizer that can be used in specific concentrations to eliminate pathogens on food contact surfaces. Quaternary ammonium compounds, or quats, are also effective sanitizers favored for their ability to remain active on surfaces and provide residual protection. Thus, the distinction lies in the intended use, safety, and effectiveness of these chemicals in a food establishment setting, where the priority is to ensure safe and hygienic food handling practices.
