The FDA issued a warning letter to San Francisco food manufacturer RDM Express Inc. after inspectors identified deficiencies in its food-safety plan, sanitation procedures and controls for refrigerated, ready-to-eat fermented cabbage products. The agency also cited labeling violations involving the company’s Russian-style kvas drink, sour cabbage and half-sour pickles. The published account does not identify a recall or report confirmed illnesses.
The Food and Drug Administration has issued a warning letter to RDM Express Inc., a San Francisco food manufacturer, citing deficiencies in its food-safety plan, sanitation procedures and controls for refrigerated, ready-to-eat fermented cabbage products. The agency also cited labeling violations involving the company’s Russian-style kvas drink, sour cabbage and half-sour pickles, according to Food Safety News’ account of the enforcement action.
The FDA’s findings concern measures intended to control pathogen risks in products that are refrigerated and ready to eat. The report says inspectors identified problems with the company’s food-safety plan, sanitation procedures and controls, but it does not describe the specific deficiencies or identify any pathogen found in the products. The agency’s warning reflects concerns about the company’s systems, not a report that contaminated food or resulting illness has been confirmed.
The cited products include fermented cabbage and other items sold by RDM Express: Russian-style kvas, sour cabbage and half-sour pickles. The report identifies labeling violations but does not give the disputed label wording, explain which rules the labels allegedly breached, or say whether all products were affected. Those details are not available in the supplied account.
Food Safety News reports that businesses generally have 15 days to respond to FDA warning letters. A response gives the company an opportunity to explain how it will address the agency’s concerns; the report does not say whether RDM Express has responded, what corrective steps it has taken, or whether the FDA has accepted any proposed actions.
Food Safety Controls Under Scrutiny
The letter matters because refrigerated, ready-to-eat foods are intended to be consumed without a further cooking step. The FDA’s stated concerns about sanitation and pathogen controls focus on safeguards used during production, while food-safety planning is meant to identify and manage hazards. The account does not establish that any product caused illness or was contaminated, but deficiencies in such controls can prompt regulatory follow-up and corrective work.
The labeling citations also affect consumers who rely on package information to identify what a product is and understand its contents. Because the report does not describe the specific violations, it is not possible to say whether they involved ingredient information, another required disclosure or a different labeling rule. The scope and practical effect of those citations remain unknown.
For customers, retailers and public-health officials, the warning provides notice that the FDA has raised concerns about a named manufacturer’s operations and labels. It is not, by itself, evidence of a recall or a determination that all of the company’s products are unsafe. The agency’s subsequent review and any documented corrective actions will help clarify the consequences.

How FDA Warning Letters Work
The FDA uses warning letters as part of its enforcement activities for businesses under its jurisdiction. Food Safety News says such letters may be posted publicly weeks or months after they are sent. It also reports that warning letters often follow periods in which companies have had months or years to address problems, though the supplied account does not establish the timeline of inspections or prior contacts involving RDM Express.
Businesses generally have 15 days to respond, according to the report. A warning letter identifies agency concerns and calls for a response; publication of a letter should not be confused with a product recall or a final account of all follow-up. Food Safety News also notes that portions of FDA letters are often redacted before public release, which can limit the detail available to readers.
The report was published on October 26, 2026. It names RDM Express Inc. and San Francisco as the company’s location, but the supplied material provides no letter date, inspection dates, product distribution information or full text of the agency’s findings.

Details Behind the FDA Citations
The account does not provide the full warning letter or specify the inspection findings behind the food-safety citations. It is not clear which pathogens or hazards the FDA considered, whether the agency found contamination, or what corrective actions it requested. No illness reports, confirmed product contamination or recall are identified in the supplied material.
The specific labeling defects are also not described. The company’s response, the status of any corrective measures, the products’ distribution and whether the FDA will take further action are unknown. The report notes that portions of warning letters can be redacted, but it does not say whether redactions apply in this case.
Company Response and FDA Follow-Up
RDM Express is generally expected to respond to the FDA within 15 days of receiving the warning letter, according to Food Safety News. The report does not specify when the letter was received, so a calendar deadline cannot be established from the available information. The company’s response and any evidence of changes to its food-safety plan, sanitation procedures or product labels would help show how it is addressing the citations.
Further updates may clarify whether the FDA considers the company’s response adequate, whether inspectors conduct follow-up work, and whether any product or enforcement action follows. Until those details are reported, the confirmed development is the warning letter and its stated categories of concern—not a confirmed recall, contamination finding or illness outbreak.
