When a Tampa Bay grocery store loses power for more than four hours, FDA Food Code §3-501.16 governs what must be discarded — but the working playbook is more nuanced than the rule reads. Here's how store ops actually decides product-by-product.
FDA Food Code §3-501.16(A) requires that potentially hazardous foods (TCS foods — Time/Temperature Control for Safety) be held at ≤41°F. §3-501.19 and the operative interpretation under FDA guidance allow TCS food to be held at 41–70°F for up to 4 cumulative hours measured from the last time it was at or below 41°F. Beyond 4 cumulative hours, discard.
"Cumulative" is the part operators miss. If product was warm for 2 hours during the outage and the store recovered, then warm again for 3 hours during a second event, that's 5 cumulative hours — discard.
The 41°F threshold is for the product, not the case air. A walk-in cooler that warmed to 50°F air for 3 hours likely has product cores still under 45°F if cases were closed and load was high. A multi-deck open case that warmed to 50°F air for 3 hours has product surfaces at or above 50°F because there was no thermal inertia.
Use a calibrated probe thermometer, take readings at the geometric center of the densest pack of product, and document the readings with timestamps and the product SKU. This is what the DBPR or local health inspector will ask for.
Discard regardless of temp/time: raw or cooked seafood, raw shellfish, soft cheese (brie, cottage, ricotta), opened deli salads, pre-cut melon and tomato, sushi rice, dairy beverages opened, infant formula opened. 4-hour clock: raw red meat, raw poultry, eggs in shell, hard cheese, butter, intact dairy in containers, deli meats sealed, hot-prepared deli items.
Generally safe even after extended outage: uncut produce, hard salami, dry-cured meats, jams and condiments unopened, hard cheese unopened, intact eggs in shell up to 7 days at ≤45°F per USDA guidance.
FDA position: frozen TCS food that has thawed must be cooked or discarded — it cannot be refrozen for sale. "Thawed" means above 32°F, even briefly. Frozen product that remained ≤32°F throughout (verified by probe at multiple SKUs in the case) can stay in inventory.
Working signal: ice crystals still present on the product and the case interior, no liquid pooling at the case bottom, no soft surface on packaged frozen items. If any of those fail, discard the affected product.
For every outage event, document: outage start time, outage end time, ambient air temp during the event, probe-thermometer readings of product cores at start, mid-event, and recovery, list of discarded SKUs by case/department with quantities, list of product retained with the basis for retention (probe reading + time at temp).
Most insurance policies covering spoilage require this same documentation for claims. Build the template before the next named storm hits.
Tampa Bay supermarkets prep for outages with backup generation sized to the refrigeration load — a typical 50,000 sq ft store needs about 250–400 kW to keep the racks and walk-ins running through an extended outage. Insurance discounts for a permanent generator with documented load testing typically pay back the install in 7–10 years; a portable generator on a quick-connect with annual rental is the alternative for smaller formats.
Pre-storm: top off any low racks (don't run a leak chase during a storm window), pre-cool walk-ins to the lower end of operating range to buy thermal mass, pre-position discard tubs, brief overnight staff on the four-hour rule.
If departments have to be closed for restock after an outage, use neutral language: "Restocking after maintenance." Don't post signage that says "product loss" — it generates customer panic and creates the impression that nearby unaffected departments may be compromised. Reopen by department as each is documented restored.
Per FDA Food Code §3-501.19, potentially hazardous (TCS) foods can be held between 41°F and 70°F for up to 4 cumulative hours measured from the last time at or below 41°F. Beyond 4 cumulative hours, discard.
No. Per FDA guidance, frozen TCS product that has thawed (above 32°F, even briefly) must be cooked or discarded — it cannot be refrozen for sale. Product that remained ≤32°F throughout, verified by probe, can stay in inventory.
Uncut produce, hard cured meats, unopened jams and condiments, unopened hard cheese, and intact eggs in shell up to 7 days at ≤45°F per USDA guidance. TCS items follow the 4-hour cumulative rule.
Yes. Document outage start and end times, ambient temperatures, probe readings of product cores, discarded SKUs by department, and the basis for any product retained. Most spoilage insurance also requires this documentation for claims.
