What is the appropriate amount of bleach for a 100 PPM chlorine sanitizing solution?

1. 1/2 ounce

2. 1 ounce

3. 2 ounces

4. 3 ounces

The correct answer is: 1 ounce

The appropriate amount of bleach needed to create a 100 PPM (parts per million) chlorine sanitizing solution is 1 ounce of bleach mixed with a specific volume of water, typically a gallon. This concentration is effective for sanitizing surfaces in food service environments, ensuring that harmful pathogens are eliminated while minimizing the risk of contaminating food and equipment. Using the correct concentration is crucial because it balances effectiveness and safety. A solution that is too concentrated can leave harmful residues on surfaces, while a solution that is not strong enough may fail to eliminate bacteria and viruses. It is important to follow guidelines for mixing sanitizing solutions carefully to maintain food safety standards. The amounts and ratios can vary depending on the specific bleach product used, so always refer to the manufacturer's instructions for accurate measurements.
