Why is it important to calibrate thermometers before their first use?

Calibrating thermometers before their first use is vital to ensure accurate temperature readings. Accurate temperature measurements are crucial in food safety, as they help prevent foodborne illnesses. If a thermometer is not calibrated correctly, it may give false readings, leading to improper cooking or storage temperatures. For instance, undercooked food may not reach a safe temperature, allowing harmful bacteria to survive. Conversely, food that is heated or cooled beyond necessary temperatures might lead to quality degradation or spoilage. Each thermometer model may have individual calibration procedures, but the overarching goal is always the same: to guarantee that temperature readings are reliable for food safety management.
