AskHACCP: ROP + Sous Vide: What Triggers a Variance (and When You Need a HACCP Plan)

Vacuum packaging and sous vide cooking are widely used to preserve food, extend shelf life, and streamline kitchen flow. But there is a clear point where these techniques move from standard kitchen use into regulated territory. That shift often requires a variance and a Hazard Analysis Critical Control Point (HACCP) Plan.

At AgriForaging Compliance Services, we receive more calls about Reduced Oxygen Packaging (ROP) and sous vide than almost any other topic. Most questions center on one issue: when does your process trigger a regulatory requirement? This guide breaks that down so you can stay compliant.

What Is Reduced Oxygen Packaging (ROP)?

ROP includes any packaging method that reduces or removes oxygen from the food environment. Common examples include:

• Vacuum sealing

• Modified atmosphere packaging (MAP)

• Controlled atmosphere packaging (CAP)

• Cook-chill processes

• Sous vide cooking in sealed bags

These methods can extend shelf life and reduce waste, but they also create low-oxygen conditions that support the growth of Clostridium botulinum, Listeria monocytogenes, and other pathogens when not properly controlled.

When You Cross Into Regulated Territory: The Triggers

Not all ROP or sous vide usage requires a variance. But many operations unintentionally cross the line. You are likely in regulated territory if any of the following apply:

• Food is vacuum packaged and held longer than 48 hours, even when refrigerated

• Sous vide items are cooked, cooled, and held before service

• ROP or sous vide items are stored for service beyond 48 hours or are distributed off-site

• Time and temperature controls deviate from the FDA Food Code

• You are using ROP on high-risk products such as:

  • Raw fish (unless frozen prior to packaging)

  • Garlic-in-oil

  • Cooked starches (such as pasta, rice, or grains) without acidification, rapid cooling, or validated controls

• You are not operating within the exemptions outlined in FDA Food Code section 3-502.12

Clarifying the 48-Hour ExemptionThe FDA Food Code allows ROP without a variance in very limited cases. To qualify for the 48-hour exemption, the following conditions must be met:

• Food is held at or below 41°F

• Product is labeled with prep and discard dates

• Cooling procedures meet Code requirements (135°F to 70°F in 2 hours, 70°F to 41°F in 4 hours)

• Logs are maintained to verify temperature and holding times

• Product is not raw fish, unless frozen before packaging

If even one of these conditions is not met, your operation falls out of the exemption and requires both a HACCP Plan and a variance.

What Is a Variance and Why Is It Required?

Variances are not blanket approvals. They are granted only when your process is backed by a HACCP Plan that addresses each hazard with documented controls. A variance is required when your process carries a higher risk and falls outside of default parameters.

To receive a variance, you must submit a validated HACCP Plan that shows your process is safe and that hazards are fully controlled.

The Role of a HACCP Plan in ROP and Sous Vide

A HACCP Plan identifies food safety hazards specific to your operation and outlines controls at every critical step. For ROP and sous vide, this typically includes:

Operational Controls

• Validated cooking temperatures and times

• Cooling logs showing product reaches 41°F within 6 hours

• Monitoring procedures for vacuum pressure and sealing integrity

• Corrective actions for seal failure, time, or temperature deviation

Documentation and Compliance

• Shelf life limits based on product validation or a maximum of 7 days

• Labeling protocols for prep and discard dates

• Staff training records

• Written Standard Operating Procedures

Your HACCP Plan must match your actual facility layout, equipment, and practices. Approval comes from your local health department or state agency, depending on your jurisdiction

Common Misunderstandings We Hear

• “I’m only vacuum sealing for portion control.” → If the food is held longer than 48 hours, you may still need a HACCP Plan and variance.

• “Everything is kept refrigerated, so it’s safe.” → Low-oxygen environments allow anaerobic pathogens to grow, even under refrigeration.

• “Sous vide is safe because the food is cooked.” → Not if time and temperature are not validated and cooling is not properly controlled.
