What is the temperature danger zone for food safety is answered by the FDA's pages cited below. The FDA's safe food handling page, cited below, says to keep the refrigerator at 40°F or below and the freezer at 0°F or below, to refrigerate perishables within 2 hours of cooking or purchasing and within 1 hour if the temperature outside is above 90°F, and its buffet guidance keeps hot foods at 140°F or warmer and cold foods at 40°F or colder. The FDA's safe cooking temperatures, from the same page: 145°F with a 3 minute rest for whole cuts of beef, pork, veal and lamb and for fin fish; 160°F for ground meat and egg dishes; 165°F for poultry, leftovers and casseroles; 140°F to reheat fully cooked ham. Storage below the cold figure, holding above the hot one, cooling through within the time: three records show a kitchen kept food out. The danger zone temperature log planner on this site prints them, free and without an account.
Storage
The refrigerator at 40°F or below and the freezer at 0°F or below, read and recorded on the plan's schedule with the limit on the sheet, and the corrective action recorded when a reading is over, with the recheck that shows the unit is back in limit.
Holding
Hot food at 140°F or warmer and cold food at 40°F or colder, probed through service at the intervals the plan sets and recorded with the time and initials on the hot food temperature check on this site. A reading inside the zone is the plan's corrective action.
Cooling
Perishables refrigerated within 2 hours of cooking or purchase, or within 1 hour when it is above 90°F outside; the cooling record shows the start and the finish and whether the limit was met. It is the record most kitchens do not keep until an inspector asks for it.
Keeping the records
Every day, with the corrective actions. ProbeLedger Pro keeps them; the planner prints them. FoodDocs lists its Lite plan at $99 per site per month billed monthly or $79 billed annually, and its Standard plan at $199 per site per month, with a free 14-day trial, on its pricing page cited below. ProbeLedger Pro is $49 per month for the whole site.
