The FDA issued a warning letter to San Francisco food manufacturer RDM Express Inc. after inspectors cited deficiencies in its food-safety plan, sanitation procedures and controls for refrigerated, ready-to-eat fermented cabbage products. The agency also identified labeling violations involving Russian-style kvas, sour cabbage and half-sour pickles; details about any products affected or a company response were not provided in the report.
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’ October 26 report, FDA inspectors found problems related to the company’s food-safety plan and sanitation, as well as controls for its refrigerated, ready-to-eat fermented cabbage. The report does not specify the pathogens at issue, describe particular findings from the inspection or identify whether any product tested positive for contamination. The reported concerns are about pathogen risks and preventive controls, not a confirmed outbreak or a confirmed contaminated product.
The FDA also cited labeling violations on Russian-style kvas, sour cabbage and half-sour pickles. The available report does not detail what information was missing or incorrect on the labels, whether the violations involved ingredient, allergen or other statements, or how many products or packages were affected. It does not report a recall.
FDA warning letters are part of the agency’s enforcement work. Food Safety News reports that businesses have 15 days to respond to a warning letter. The report does not provide the date the agency sent this letter, so the start or end of RDM Express’s response period cannot be established from the information available.
Food Safety Controls Under Review
Refrigerated, ready-to-eat foods are sold for consumption without a further cooking step, making sanitation and preventive controls relevant to reducing the possibility of pathogen contamination. The FDA’s cited deficiencies signal that the agency has identified issues requiring a response from the manufacturer. They do not, on the information reported, establish that consumers became ill or that the products were contaminated.
Labeling concerns also matter to shoppers because package information helps consumers identify what a product contains and make purchasing decisions. Since the report does not describe the specific labeling defects, readers cannot determine whether they relate to allergens, product identity or another requirement. No recall or direct consumer warning is described in the source material.

How FDA Warning Letters Work
The FDA sends warning letters to companies under its jurisdiction as part of its enforcement activities. Food Safety News says such letters may not be posted publicly until weeks or months after they are sent. It also reports that companies are sometimes given months or years to correct problems before a warning letter is issued, and that portions of letters may be redacted before publication.
A warning letter is an agency notice identifying concerns and seeking a response; it is not, by itself, evidence that a reported hazard caused illness. In this case, the published account identifies RDM Express and the broad areas cited by the FDA, but offers no detailed inspection findings, response from the company or account of subsequent regulatory action.
Inspection Findings Still Missing
The available report leaves several material details unanswered. It does not give the inspection dates, the warning letter’s date, the specific pathogens or control failures cited, or the exact label statements the FDA found deficient. It also does not say whether the agency collected samples, whether products remain on sale, or whether RDM Express has corrected the issues.
No company comment is included, and the report does not describe a product recall, illness reports or confirmed contamination. Those points should not be inferred from the FDA’s citations. The scope and seriousness of the findings cannot be assessed fully without the warning letter’s detailed observations and the company’s response.
Company Response and FDA Follow-Up
RDM Express is expected to respond to the FDA warning letter within 15 days, according to the general response period described by Food Safety News. The report does not state when that period began for this company or whether its response has already been submitted.
The next useful developments would be publication of the full letter or additional detail about the inspection, a response from RDM Express, and information from the FDA about any corrective steps or further enforcement. Until then, the reported concerns remain agency findings about food-safety controls and labeling; no recall or confirmed consumer illness is established by the source material.
Key Questions
Why did the FDA issue a warning letter to RDM Express?
The FDA cited deficiencies in the company’s food-safety plan, sanitation procedures and controls for refrigerated, ready-to-eat fermented cabbage products. It also cited labeling violations involving Russian-style kvas, sour cabbage and half-sour pickles.
Did the FDA confirm that the products were contaminated?
The report does not say that any product tested positive for a pathogen. It describes pathogen risks and deficiencies in controls, not confirmed contamination or a linked illness.
Were the products recalled?
No recall is reported in the available source material. The FDA’s warning letter and the cited deficiencies do not, on their own, establish that a recall occurred.
What labeling violations did the agency identify?
The report identifies the product categories but does not describe the specific label errors or say whether they involved allergens, ingredients or other information.
What happens after a warning letter?
Food Safety News reports that businesses have 15 days to respond to FDA warning letters. The report does not say whether RDM Express has replied or what corrective action the FDA may take.
