Food Safety and Packaging Rules for Delivery Orders: What Health Departments Require (2026)

Q: How long can hot food sit before it's unsafe for delivery?

Under the FDA Food Code, temperature-control-for-safety (TCS) food cannot stay in the 41-135°F danger zone for more than a cumulative 4 hours before it must be discarded. Bacteria like Salmonella and E. coli can double every 20 minutes in that range, so a delivery order sitting out for pickup, or a slow courier, eats directly into that 4-hour clock.

Q: Does a food truck have to seal delivery orders with a tamper-evident label?

California requires it by law under AB-3336, effective since January 1, 2021: every bag or container of ready-to-eat food handed to a third-party delivery driver must be sealed with a tamper-evident method (a sticker, a sealed bag, or a container with built-in tamper protection) before the driver takes possession, and the food business is responsible for doing the sealing. Other states don't currently have an identical statewide law, but treat sealing as a baseline food-safety and liability practice everywhere, not just where it's mandatory.

Q: What temperature does hot and cold food need to stay at during delivery?

Cold TCS food must stay at 41°F or below and hot TCS food at 135°F or above. Outside that range is the danger zone where the 4-hour clock starts running. Insulated bags, hot-holding units, and cold packs are how trucks keep food out of that zone during the gap between handoff and delivery.

Q: What should a food truck reject if a delivery courier's setup looks wrong?

You control packaging up to the handoff, not what happens after. Package correctly, seal it, and mark it ready in the app the moment it's staged. If you're the one receiving supply deliveries (not sending orders out), reject any delivery that arrives with damaged packaging or out-of-range temperatures rather than accepting it and hoping.

Q: Do prepackaged snacks or drinks need tamper-evident sealing for delivery?

No. California's AB-3336 specifically exempts prepackaged, non-potentially-hazardous foods (things like a bagged chip or a factory-sealed bottled drink) from the tamper-evident sealing requirement, since those already come sealed from the manufacturer. The rule targets ready-to-eat food your truck prepares and bags in-house.

Running orders through DoorDash, Uber Eats, or Grubhub adds a step your walk-up window doesn't have to deal with: the food sits in a bag, in a car, for minutes you don't control. Health departments have real rules for that gap. Here's what the FDA Food Code actually requires on temperature and time, what California's tamper-evident sealing law covers, and a practical packaging checklist for a truck sending orders out the window.

The 4-hour rule: temperature and time limits

The FDA Food Code defines the "temperature danger zone" as 41°F to 135°F, the range where bacteria like Salmonella, E. coli, and Clostridium perfringens can double in number every 20 minutes. Time/Temperature Control for Safety (TCS) foods, cooked meats, rice, beans, sauces, cut produce, basically anything that supports bacterial growth, cannot sit in that danger zone for a cumulative total of more than 4 hours before it must be discarded. That clock doesn't reset when the food changes hands: prep time, staging time waiting for a courier, and transit time all count against the same 4 hours. Cold TCS food has to stay at 41°F or below and hot TCS food at 135°F or above for the whole trip, which is why insulated delivery bags and hot-holding equipment aren't optional extras for a truck running regular delivery volume.

Rule	Requirement
Cold holding	41°F or below
Hot holding	135°F or above
Max cumulative time in danger zone	4 hours, then discard
Cooked food cooling, stage 1	135°F → 70°F within 2 hours
Cooked food cooling, stage 2	70°F → 41°F within a total of 6 hours

California's tamper-evident sealing law (AB-3336)

California's AB-3336, in effect since January 1, 2021, requires every bag or container of ready-to-eat food handed to a third-party delivery driver to be sealed with a tamper-evident method before the driver takes possession, and the food facility (your truck or commissary) is responsible for doing the sealing, not the delivery platform. The law doesn't mandate one specific product, common solutions are tamper-evident stickers across the bag opening, sealed bags with a security strip, or containers with built-in tamper features. It also requires the food to be transported in a clean holding area at the proper temperature and protected from contamination during transit. Prepackaged, non-potentially-hazardous items (a bagged chip, a factory-sealed drink) are exempt, since they already arrive sealed from the manufacturer.

Does this apply outside California?

As of now, California is the state with a specifically named statewide law requiring tamper-evident sealing for third-party delivery orders. No other state currently has an identical statute on the books, though food-safety industry coverage has noted more states are expected to follow that pattern over time. Practically, that means: if you're operating in California, tamper-evident sealing is a legal requirement with real liability exposure for skipping it. If you're operating anywhere else, it's not currently a state mandate, but it's still the right baseline practice, it protects you from customer disputes about contamination, and if your state does add a similar law you'll already be compliant.

Practical packaging checklist

Keep hot food hot and cold food cold at the moment of bagging. Don't stage food on the counter waiting for a courier, that's when it starts losing temperature and eating into the 4-hour clock.
Seal every bag before it leaves your hands. A sticker across the bag opening or a sealed-bag system, whichever you use consistently, not just for California orders if you operate there, but as standard practice everywhere.
Use insulated bags for hot items and cold packs for anything temperature-sensitive. A standard delivery bag alone won't hold 135°F for a 20-minute drive in a hot car.
Label the outside with the order number and customer name so a courier can match it to the app without opening it to check.
Mark the order "Ready" in the platform's app the instant it's staged, not before it's actually sealed and ready to hand off, since an early "Ready" status can mean the food sits longer in the danger zone waiting for pickup.
Track prep-to-handoff time on your busiest delivery days. If orders are regularly sitting more than 20-30 minutes before a courier arrives, that's a platform routing or staffing issue worth raising with your account manager, not something packaging alone fixes.

What the delivery platforms themselves expect

Beyond the legal requirements, DoorDash, Uber Eats, and Grubhub all expect merchants to have basic packaging supplies on hand for delivery orders: bags, tissue or dividers for anything fragile, and cold packs or insulated containers for temperature-sensitive items. None of this is exotic or expensive, it's the same packaging a decent takeout counter already uses, the difference for delivery is that nobody from your truck is there to catch a problem before the customer opens the bag, so the packaging has to do that job on its own.

Frequently asked questions

How long can hot food sit before it's unsafe for delivery?

TCS food cannot stay in the 41-135°F danger zone for more than a cumulative 4 hours before it must be discarded, and that clock includes prep, staging, and transit time combined.

Does a food truck have to seal delivery orders with a tamper-evident label?

California requires it under AB-3336, effective since January 1, 2021. Other states don't currently have an identical law, but sealing is a smart baseline practice everywhere.

What temperature does hot and cold food need to stay at during delivery?

Cold TCS food at 41°F or below, hot TCS food at 135°F or above, for the entire trip from prep to customer.

What should a food truck reject if a delivery courier's setup looks wrong?

You control packaging only up to handoff. Package correctly, seal it, and mark it ready only when it's actually staged and sealed.

Do prepackaged snacks or drinks need tamper-evident sealing for delivery?

No, California's AB-3336 exempts prepackaged, non-potentially-hazardous foods since they already arrive sealed from the manufacturer.

Keep your health permit and food-safety paperwork current before delivery volume grows.
