What Temperature Should Inflight Catering Be Kept at an FBO?

Temperature is the most important variable in inflight catering safety between delivery and service. The FDA's food safety framework defines clear requirements — and understanding them protects both passengers and the operation handling the food. Here's the complete temperature reference for FBO operations teams, flight attendants, and anyone in the catering chain.

The Critical Numbers

Cold hold: 40°F (4°C) or below — this is the required storage temperature for all cold perishable items from production through service.

Hot hold: 140°F (60°C) or above — for any items delivered hot that need to be held for service.

The Danger Zone: 40°F–140°F (4°C–60°C) — the temperature range where foodborne pathogens multiply most rapidly. Food should never be held in this zone for more than 2 hours total (from production through service).

Cold Items: What You Need to Know

Every cold perishable item — proteins, dairy, prepared foods, produce in prepared form — should be held at or below 40°F from the moment it leaves the catering kitchen through the moment it's served to the passenger. At an FBO, this means:

• FBO refrigeration must be set and verified at 34–40°F (slightly below the maximum to provide safety margin)
• Catering should not be left at room temperature for any extended period — "just a few minutes" adds up across the transit chain
• If you're unsure of an item's temperature history and it may have been above 40°F for more than 2 hours, it should not be served

Hot Items: Maintaining Temperature

DFK generally does not deliver hot items for transit window serving — the cold chain plus galley reheat model is more reliable. However, some items (soups, certain sauces) may be delivered in hot-hold containers. These must be maintained at 140°F or above until served.

FBOs that receive hot-hold items should have a warming capability (warming cart, hot holding unit) sufficient to maintain these temperatures, or the delivery should be timed to arrive immediately before aircraft loading.

Practical Testing

A simple probe thermometer (under $30 at any restaurant supply store) allows immediate temperature verification at any point in the chain. DFK recommends that FBOs receiving catering maintain a probe thermometer at their receiving area and spot-check incoming deliveries — not because our cold chain fails, but because the additional verification protects everyone in the chain.

When Temperature Fails

If you receive a catering delivery that is above 40°F — documented by thermometer check — contact DFK dispatch immediately: +1 (866) 328-7905. We'll assess whether the item is safe to serve (based on the temperature and time since production) or whether a replacement is needed. Do not serve items with questionable temperature history without verification.
