Question

the most effective control measure to prevent food - borne illness is:
time - temperature control
ph control
inventory control
dishwashing control

Explanation:

Time - temperature control is crucial as it prevents the growth of harmful bacteria in food. Bacteria that cause food - borne illness multiply rapidly in the "danger zone" (41°F - 135°F or 5°C - 57°C). By controlling time (how long food is in the danger zone) and temperature (keeping food out of the danger zone through proper cooking, cooling, holding), the risk of food - borne illness is significantly reduced. pH control mainly affects food spoilage in some fermented foods but is not the most comprehensive measure for all food - borne illness prevention. Inventory control is about stock management and not directly related to killing or preventing bacterial growth. Dishwashing control is about cleaning utensils but does not address the core issue of bacterial growth in food itself.
