Publishing rapid-test results properly: from verification to traceable corrections
China’s market regulator sets out how food businesses should publish, correct and keep records of on-site rapid-test results. Here is what that means in practice.
Rapid food testing supports the initial screening of edible agricultural products and other foods, but its value goes beyond “getting a result”. The result also has to stand up to verification and be traceable. The State Administration for Market Regulation (SAMR) guidance on the use of rapid food testing sets specific requirements for how rapid-test information is published. For markets, supermarkets and canteens that run their own checks, a clear process for publishing and correcting results is what links on-site screening to day-to-day risk management.
Be clear about what a rapid test is for
Rapid tests are designed for fast screening and risk checks. They are not statutory test conclusions. When a positive or suspicious result appears on site, it should not be presented as a final safety verdict, and it cannot replace follow-up verification, retesting or official sampling. A complete record of the screening result, sample details, test item, time and follow-up action helps uncover risk signals and gives a basis for later review.
Publish information that is accurate, clear and checkable
A well-structured notice covers the sample tested, sampling time and place, test item, result and testing unit, and avoids wording that could mislead. Public result boards work best with a consistent format and a fixed location so they are easy to find and compare. Internally, results can be linked to the batch, supplier, retained sample or retest in the ledger. Digital tools make records easier to search, but they depend on accurate source data and a traceable collection process.
Correct errors promptly — and keep the trail
The guidance states that when published rapid-test information turns out to be wrong, the publisher must correct it promptly in the same channel. In practice, “detect → verify → correct → explain” should be a fixed routine. Check the sample and item first, then decide whether the error came from data entry, reading or linked information. Update the correct content in the original channel and record when, why and by whom the correction was made.
Feed screening results into the risk-handling loop
Rapid-test information should not stop at a notice board or a one-off spreadsheet. For abnormal signals, actions can include suspending sales, confirmation testing, retaining samples for laboratory analysis or cooperating with regulators, based on the supply batch, sales destination and similar products. Batches confirmed as normal should also keep the necessary records, so the data can be reviewed and analysed. Specific actions must follow applicable law and local regulatory requirements. Rapid results serve as an early warning, not a substitute for statutory testing.
From a single result sheet to a credible record
Food safety management shows in the details of every sampling, reading, publication and correction. Food businesses should regularly check that their rapid-test records are complete, published content is consistent and the abnormal-result process is clear, and keep a simple, workable ledger for their own type of operation.
