Fermented foods—such as kimchi, sauerkraut, kombucha, yogurt-based products, fermented sauces, and pickled vegetables—are rapidly growing in popularity across the United States. While these products are often rooted in traditional processes, they must still meet strict U.S. regulatory requirements before they can be legally sold.

The U.S. Food and Drug Administration regulates fermented foods as part of the broader food supply, with requirements covering facility registration, labeling, safety, and in some cases, process controls.

Because fermentation involves biological activity and pH changes, these products can fall into more complex regulatory categories. Ensuring compliance from the beginning is essential to avoid delays, detention, or refusal at the port of entry.

What Are Fermented Foods

Fermented foods are products that undergo controlled microbial processes to develop flavor, texture, or preservation.

Common examples include kimchi, sauerkraut, yogurt, kefir, kombucha, fermented sauces, and pickled vegetables.

These products may be refrigerated, shelf-stable, or require controlled storage conditions.

Fermentation can affect acidity, shelf life, and safety.

Because of these factors, regulatory classification depends on the specific product and process.

Do Fermented Foods Require FDA Registration

Yes, any facility involved in manufacturing, processing, packing, or holding fermented foods must be registered with the FDA.

This applies to both domestic and foreign facilities.

Foreign facilities must designate a U.S. Agent as part of their registration.

Registration must be active and properly maintained.

Without valid registration, fermented food products cannot legally enter the U.S. market.

When Process Filing May Be Required

Some fermented foods may require additional FDA process filings depending on their characteristics.

Acidified foods, such as certain pickled or fermented products, may require process filing.

Products that rely on controlled pH levels for safety may need validation.

Shelf-stable fermented products may fall under additional regulatory requirements.

If applicable, facilities may need to obtain a Food Canning Establishment (FCE) number and file Scheduled Processes (SIDs).

Role of pH and Safety Controls

pH plays a critical role in the safety of fermented foods.

Products must maintain safe pH levels to prevent microbial growth.

Fermentation processes must be controlled and consistent.

Testing and validation may be required to ensure safety.

Improper control of fermentation conditions can lead to compliance issues.

FSVP Requirements for Imported Fermented Foods

If fermented foods are manufactured outside the United States, the importer must comply with the Foreign Supplier Verification Program (FSVP).

The importer must verify that the foreign supplier meets FDA food safety standards.

This includes reviewing hazard analyses, fermentation controls, and documentation.

Records must be maintained for FDA inspection.

FSVP is required for all imported fermented food products.

Labeling Requirements for Fermented Foods

Labeling is one of the most critical compliance areas for fermented foods.

The label must clearly identify the product.

All ingredients must be listed in descending order by weight.

A compliant Nutrition Facts panel must be included unless exempt.

Allergen declarations must be clearly stated.

Net quantity and responsible party information must be included.

Fermented products often contain complex ingredient combinations, making accurate labeling essential.

Claims and Marketing Considerations

Fermented foods often include health-related claims that require careful attention.

Claims such as “probiotic,” “gut health,” or “natural fermentation” must be accurate and substantiated.

Claims must not be misleading or unsupported.

Product identity must clearly reflect the nature of the product.

Improper claims are a common reason fermented products are flagged.

Common Compliance Issues with Fermented Foods

Fermented food products often encounter recurring compliance challenges.

Misclassification of acidified versus fermented products.

Lack of proper process validation where required.

Ingredient lists that do not fully reflect the formulation.

Claims that do not meet FDA standards.

These issues can lead to delays, detention, or refusal.

Why a Compliance Review Is Essential

A compliance review helps identify and resolve issues before products reach the U.S. market.

It ensures proper classification of the product.

It verifies whether process filing is required.

It ensures labeling meets FDA standards.

It helps address FSVP and documentation requirements.

Many businesses use compliance reviews as a standard step when launching fermented food products.
