How should 50 PPM chlorine-based sanitizing solutions be prepared?

To prepare a 50 PPM (parts per million) chlorine-based sanitizing solution, the correct method involves adding 1/2 ounce of bleach to 1 gallon of water. This specific concentration ensures that the solution is effective in killing microorganisms without being overly concentrated, which could cause harmful effects or damage surfaces.

Chlorine bleach solutions can vary in concentration, but the typical dilution that achieves 50 PPM involves using 1/2 ounce of standard bleach per gallon of water. This dilution strikes a balance that is strong enough to sanitize but still safe for food contact surfaces, as well as ensuring compliance with health and safety regulations. Proper preparation of sanitizing solutions is critical for ensuring food safety in any food service environment.
