What does "ppm" stand for in a food service context?

In a food service context, "ppm" stands for "parts per million." This term is commonly used to quantify the concentration of a substance in a solution or mixture. For example, when discussing food safety, particularly in relation to sanitizers or chemical residues, ppm helps determine the safety levels of certain chemicals that may be present in food items or food contact surfaces. Understanding this measurement is crucial for ensuring compliance with health regulations and maintaining high food safety standards.

This concept is especially important in scenarios where very low concentrations of a substance must be monitored, such as in the case of allergens, toxins, or microbial contaminants in food. Knowing ppm values enables food service workers to make informed decisions about food safety and quality.
