What the record shows
Industry reporting on airline catering audits identifies improper temperature control as a standard violation category. Findings include thermometers recorded as deviating substantially from true temperature.
Evidence gap
Where a temperature record is produced by an uncalibrated or deviating instrument, the record itself is unreliable. No public mechanism identifies which historical records were affected by instrument error, or what the true temperatures were.
A temperature record is only as reliable as the instrument that produced it. Calibration traceable to a recognised standard is what allows a reading to be relied upon after the fact.
