The plain-words read of this example
The lot spent 95 min above 41°F, peaking at 48.0°F, for an exposure of 333 °F·min against an allowance of 240. With earlier legs it has 125 min above the limit, of the 240 the Food Code allows for TCS food. Readings every 15 min mean the true time could be 125 min, and the call at that worst case is "hold: exposure over allowance, qa review". Hold and tag; the quality lead decides from the HACCP plan and the logger file. $18,000.00 rides on the decision, so keep the logger file and the temperature instruction with the claim.
