The FDA issued a warning letter to San Francisco food manufacturer RDM Express Inc. after identifying 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 source report does not specify whether products were recalled or whether anyone became ill.
The Food and Drug Administration 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 a report published by Food Safety News on October 26.
The FDA’s cited concerns cover several areas of the company’s operations: its food-safety plan, sanitation procedures and controls for refrigerated, ready-to-eat fermented cabbage. The source report does not provide the detailed inspection findings or identify a specific pathogen found in the products. The warning concerns pathogen risks and food-safety controls; it does not establish that contamination occurred.
The agency also identified labeling violations involving Russian-style kvas, sour cabbage and half-sour pickles. The report does not state what information was missing or incorrect on the labels, which products or batches were affected, or whether the FDA required a particular correction for each item.
The report identifies the recipient as RDM Express Inc. of San Francisco. It does not say when the FDA sent the letter, when inspectors visited the facility, whether products remain on sale, or whether the company has responded. Those details are not confirmed in the available account.
Food Controls and Product Labels
The letter signals that federal regulators found issues they considered serious enough to raise formally with a food manufacturer handling refrigerated, ready-to-eat products. Such products are intended to be eaten without a further cooking step, making the adequacy of the company’s food-safety controls and sanitation procedures relevant to consumers. The warning identifies areas needing attention, but the source report does not establish that any product caused illness or contained a pathogen.
Labeling matters for a different reason: shoppers use product information to understand what they are buying and to make choices based on their needs. The FDA’s cited violations apply to several named products, but the report gives no detail about the specific label defects. Without that information, readers cannot determine from the report whether the issues involved ingredients, required statements or another labeling requirement.
A warning letter is a regulatory notice, not itself a recall announcement. The report does not say that the FDA ordered a recall, that RDM Express withdrew products, or that a public health alert was issued. Consumers should not treat the letter alone as evidence of a confirmed outbreak or contaminated food.

How FDA Warning Letters Work
The source report describes warning letters as part of the FDA’s enforcement activities. It says companies generally have 15 days to respond to a warning letter. That response period is a chance for a company to address the agency’s concerns; the report does not say what RDM Express submitted or whether its response was accepted.
Food Safety News also notes that warning letters may be posted publicly weeks or months after they are sent. It says letters often follow extended opportunities for companies to correct problems and that portions may be redacted. The publication date, October 26, 2026, therefore does not establish when FDA inspectors observed the deficiencies or when the agency sent its letter.
In this case, the publicly described concerns span both production practices and product information: food-safety planning, sanitation, refrigerated fermented cabbage controls and labeling for kvas, sour cabbage and half-sour pickles. The available report supplies no facility inspection dates, specific regulatory citations or excerpts from the warning letter.
“Some letters are not posted for public view until weeks or months after they are sent.”

Inspection Findings Still Unspecified
The available account does not identify a pathogen detected at the facility, report contaminated product, or link the company’s food to an illness or outbreak. It also does not disclose the specific sanitation or food-safety-plan deficiencies, the exact label problems, or which product batches were involved. The distinction matters: the FDA’s warning describes regulatory concerns, not a confirmed contamination event in the information provided.
It remains unclear when the inspection and warning letter occurred, whether products were recalled or removed from sale, and whether the company has corrected the cited problems. The source report also does not include a statement from RDM Express or the full text of the agency’s letter. No conclusion about the company’s current compliance can be drawn from the report alone.
Company Response and FDA Follow-Up
Under the general procedure described by Food Safety News, a business has 15 days to respond to an FDA warning letter. The report does not establish the date that period began for RDM Express, so it is not possible to calculate a response deadline from the information available.
Further information could clarify the agency’s inspection observations, the corrective actions requested and whether the company has addressed them. FDA follow-up or publication of additional details may establish whether the cited deficiencies were resolved. The source report does not announce a recall, a deadline for corrective work beyond the general response period, or a scheduled next regulatory action.
