Flavor or preservation: the one question that decides it
The Food Code does not ask whether you own a smoker. It asks why you are smoking. Section 3-502.11 lists the processes that need a variance before you start, and smoking is the first:
FDA Food Code 2022, 3-502.11(A)Smoking FOOD as a method of FOOD preservation rather than as a method of flavor enhancement;
Annex 6, the Food Code's processing guidance, draws the same line from the other side:
FDA Food Code 2022, Annex 6, 2(H)(3)Smoking which meets the time/temperature parameters in Section 3-401.11 does not require a variance.
FDA Food Code 2022, Annex 6, 2(H)(3)Cold smoking where the temperature achieved by the product is greater than 41ºF requires a variance.
So the test is practical. If the smoke adds flavor to food you then cook to the normal temperatures, and you handle it like any other cooked food, you are smoking for flavor. If the smoke, the salt and the cold are what keep the food safe for days, you are smoking to preserve, and you need a variance and a HACCP plan.
- Is it cured (salt cure, nitrite) before smoking?Yes: curing variance, 3-502.11(B)
- Does the product reach its 3-401.11 cooking temperature in the smoker?No: cold smoking. Variance if the product goes above 41°F
- Will you vacuum pack it, or keep it longer than the normal date mark, relying on smoke and salt?Yes: preservation, 3-502.11(A)
- None of the above?Flavor smoking. Normal rules: cook, hold, cool, date mark.
| Item | Call | Why | What you need |
|---|---|---|---|
| Smoked brisket, cooked through, served hot from the pit | Flavor | Cooked to 3-401.11(A)(1) or the roast chart, then hot held at 135°F or above | Normal Food Code rules. No variance. |
| Pulled pork smoked today, cooled, reheated tomorrow | Flavor | Cooked, then cooled (3-501.14(A)(1)) and reheated to 165°F (3-403.11(A)) | Normal rules plus a cooling log. No variance. |
| Smoked chicken wings | Flavor | Cooked to 165°F in the smoker (3-401.11(A)(3)) | Normal rules. No variance. |
| Hot-smoked trout, cooked through, chilled, served within its date mark | Flavor, usually | Reaches 145°F for 15 s during the smoke; Annex 6 says smoking that meets 3-401.11 needs no variance | Ask your health department how it reads a brined fish. Vacuum packing it needs a variance. |
| House bacon or pastrami | Curing | The cure is the special process, whatever the smoke does | Variance under 3-502.11(B) and a HACCP plan. See the curing guide. |
| Cold-smoked salmon held for days | Preservation | Never cooked; salt, smoke and cold are the controls, and product often goes above 41°F in the smoker | Variance under 3-502.11(A) and (B), HACCP plan, parasite control. |
The flavor and preservation wording is the Food Code's, and states adopt it in different editions and sometimes with their own words. A brined, hot-smoked fish is the most common gray zone. Ask before you print the menu, and check your state page.
Hot smoking vs cold smoking
Annex 6 describes smoking broadly:
FDA Food Code 2022, Annex 6, 3(D)Smoking is the process of exposing meat products to wood smoke. Depending on the method, some products may be cooked and smoked simultaneously, smoked and dried without cooking, or cooked without smoking.
Hot smoking
The smoke and the heat arrive together, and the food cooks. Brisket, ribs, wings, hot-smoked trout. What makes it safe is the cook: 145°F for 15 seconds for fish and whole-muscle meat, 155°F for 17 seconds for ground meat sausage, 165°F for poultry (3-401.11(A)(1) to 3-401.11(A)(3)). The probe decides, not the bark.
Cold smoking
The smoke is kept cool so the food never cooks. Cold-smoked salmon, smoked cheese, some sausages before drying. Nothing in the smoker kills bacteria or parasites. What makes it safe is a cure before, controlled temperature during, and cold holding after, which is why it needs a variance when the product goes above 41°F.
Annex 6 also asks every smoking operation for a written procedure that keeps contamination out, and for smokehouses to be tested when installed:
FDA Food Code 2022, Annex 6, 3(D)As with curing operations, a standard operating procedure must be established to prevent contamination during the smoking process.
FDA Food Code 2022, Annex 6, 3(F)(3)When smokehouses are initially installed or structurally modified, calibration of product heating characteristics must be ascertained by competent food technologists.
Why smoked fish is the hard case: C. botulinum
Smoked fish has a history the Food Code does not let anyone forget:
FDA Food Code 2022, Annex 6, 2However, the early use of vacuum packaging for smoked fish had disastrous results, causing a long-standing moratorium on certain uses of this technology at the retail level.
The organism is Clostridium botulinum, and some types grow at refrigerator temperatures. Annex 3 notes that non-proteolytic strains can make toxin in cold food:
FDA Food Code 2022, Annex 3, 3-502.12C. botulinum spores are able to germinate and produce toxin at temperatures down to 3ºC (38ºF).
That is colder than 41°F, the normal cold holding limit. Oxygen helps hold it back, which is why packing smoked fish in a vacuum bag changes everything:
FDA Food Code 2022, Annex 6, 2(H)(1)Unfrozen processed fish and smoked fish may not be packed by ROP unless retail food establishments have an approved variance application and HACCP plan to show C. botulinum spore germination and toxin production or L. monocytogenes growth will not occur and are inspected by the regulatory authority.
Fish processors control this hazard with a combination of salt in the fish, smoke, temperature and packaging, set out in FDA's Fish and Fishery Products Hazards and Controls Guidance, chapter 13 (C. botulinum toxin formation). A cold-smoked fish HACCP plan uses that guidance as its scientific support, and your health department may ask for lab testing of salt levels in the finished fish. We do not quote its numbers here because they are not in the Food Code text; the plan cites the edition it relies on.
Listeria is the other concern. Cold smoking does not kill it and it grows in the cold, so smoked fish made in house is date marked, with no exemption:
FDA Food Code 2022, Annex 3, 3-501.17This exemption does not apply to hot or cold smoked fish products, nor does it apply to fish products that are dried, marinated, or otherwise preserved on-site, in a food establishment, such as ceviche.
Parasites in cold-smoked fish
Hot smoking to 145°F is a cook, and the cook takes care of parasites. Cold smoking is not, and the Food Code names cold-smoked salmon specifically:
FDA Food Code 2022, Annex 3, 3-201.11fish from natural bodies of water may carry parasitic worms that can infect and injure consumers who eat such raw fish dishes as sushi, ceviche, green (lightly marinated) herring, and cold-smoked salmon.
Under 3-402.11 the fish is frozen before service using one of three options, or bought frozen with a supplier statement:
| Option | Freeze and hold |
|---|---|
| 3-402.11(A)(1) | -4°F or below for 168 hours (7 days) |
| 3-402.11(A)(2) | -31°F until solid, held at -31°F for 15 hours |
| 3-402.11(A)(3) | -31°F until solid, held at -4°F for 24 hours |
Freezing records or the supplier letter are kept for 90 days after the fish is served (3-402.12). Aquacultured salmon raised on formulated, parasite-free feed is exempt under 3-402.11(B)(4), with a written statement from the supplier. Chapter 5 of the FDA fish guidance covers parasites in more depth.
What the smoking plan covers
A HACCP plan under 8-201.14 has the same parts for every process: the foods it covers, a flow diagram with the critical control points marked, the recipe and equipment, a CCP table, and the procedures and records behind it. For a smoking plan, these are the parts reviewers read hardest:
- Raw material. Species and source for fish; the parasite paperwork; the receiving temperature.
- Brine or cure. Recipe by weight, how it is mixed, how cold it is kept, how long. If it contains nitrite, it is also a cure (see curing).
- The smoke. Smoker type, load, wood, and the product temperature it reaches. For a hot smoke, the cook limit and how it is probed.
- Cooling. From 135°F to 70°F within 2 hours, then to 41°F within 6 hours total (3-501.14(A)(1)).
- Storage. Cold holding at 41°F or below, containers, labels, date marking. No vacuum bags unless the variance covers them.
- Records. Annex 6 is direct about it:
FDA Food Code 2022, Annex 6, 3(F)(3)Time/temperature parameters of the cooking process must be monitored and recorded.

Cold-smoked fish: always a human review
Everything about cold-smoked fish is a judgment call between salt, smoke, temperature, time and packaging, with a toxin that cannot be seen, smelled or cooked out. We do not let software make that call alone.
Every cold-smoked fish plan goes to a person for review before it is released. We are not selling them yet: they open once an independent food safety professional has reviewed that rule pack in writing. You can start the plan in the builder now, and we will email you when it is ready. Hot smoking for flavor builds straight away.
If your menu needs cold-smoked fish now, a consultant or process authority with seafood experience is a sound choice.
What plan reviewers look for, and common mistakes
- Calling it flavor when it is not. If smoked fish sits in the walk-in for a week or goes into a vacuum bag, the smoke is doing preservation work. Say so and get the variance.
- Smoker temperature instead of product temperature. The limit is the internal temperature of the thickest piece. A smoker dial reading is not a critical limit.
- No cooling plan. Big smoked cuts cool slowly. Slice or portion, spread on racks, then chill; log both checkpoints.
- Missing parasite paperwork. Cold-smoked or lightly smoked fish without freezing records or a supplier letter is the first thing an inspector asks for.
- No date marks. In-house smoked fish is never exempt.
- A variance kept in the office. Under 8-103.12(A) the approved variance is kept at the food establishment.
The variance request itself follows 8-103.11: a statement of the variance with the Code sections, the rationale for how the hazards are controlled another way, and the HACCP plan.
FDA Food Code 2022, 8-103.11(C)A HACCP PLAN if required as specified under ¶ 8-201.13(A) that includes the information specified under § 8-201.14 as it is relevant to the VARIANCE requested.
