What is one way to ensure food safety during delivery?

Using insulated containers to maintain temperature is a best practice for ensuring food safety during delivery. Insulated containers help keep hot foods hot and cold foods cold, which is crucial for preventing the growth of harmful bacteria that can occur when food is held in the "danger zone" temperature range (typically between 40°F and 140°F). By maintaining proper temperatures during transport, you significantly reduce the risk of foodborne illnesses, ensuring that the food remains safe for consumption upon arrival.

The other options do not align with food safety standards. Keeping food containers open can expose food to contaminants and compromise hygiene. Storing food at room temperature for extended periods increases the risk of bacterial growth. Delaying delivery to allow food to cool could lead to food entering unsafe temperature ranges, further increasing the risk of foodborne illness. Thus, using insulated containers is the most effective way to safeguard food safety during delivery.
