What is the recommended PPM for the test strip reading of Q-san?

The recommended parts per million (PPM) for the test strip reading of Q-san is between 150 and 400 PPM. This range is important because it ensures effective sanitization while being safe for use in food handling environments. A reading within this range indicates that the solution has the appropriate concentration to eliminate harmful pathogens without leaving harmful residues on food contact surfaces. Concentrations below 150 PPM may not effectively disinfect surfaces, while values exceeding 400 PPM could potentially cause harm or undesirable effects on food products and surfaces. Therefore, maintaining the concentration within this specified PPM range is crucial for both safety and effectiveness in produce management and sanitation practices.
