Microbiological Testing in Shilajit: What the Bureau Veritas Report Shows

Microbiological testing checks a Shilajit sample for organisms and microbial indicators relevant to hygiene and product quality. Golden Shilajit batch SLJT01LQ was submitted for microbiological analysis through Bureau Veritas laboratory services. The results documented here are batch-specific and do not represent every future batch.

Why Microbiological Testing Matters in Shilajit

Microbiological analysis is a standard component of food and supplement quality control. It checks whether a product sample contains microbial indicators or pathogens at levels that could be relevant to product hygiene and safety.

Raw Shilajit is collected from high-altitude mountain rock faces and is exposed to environmental conditions during collection and initial processing. Properly purified Shilajit undergoes multi-stage processing that reduces microbial load. Independent microbiological testing by an accredited laboratory provides documented evidence of the microbial status of a specific batch at the time of testing.

This does not mean all Shilajit is microbiologically unsafe. It means that responsible manufacturers test each batch and make the results available for review. For a broader overview of why independent laboratory testing matters, see: Why Lab Tested Shilajit Matters.

What Was Tested in Batch SLJT01LQ?

The following report identifiers apply to the microbiological analysis documented in this article.

Bureau Veritas Microbiological Results

The following results are taken directly from Bureau Veritas Report No. 1086405 for batch SLJT01LQ.

Source: Bureau Veritas Test Report No. 1086405, Job/Sample No. AEDFL2213391-001, reported 06 May 2026. Results apply to the tested batch only.

What Does <10 cfu/g Mean?

A result of <10 cfu/g means the measured count was below 10 colony-forming units per gram — specifically, below the reporting threshold of the method used in this analysis. It does not mean the count is definitively zero. It means the laboratory did not detect a quantifiable level above the method’s lower reporting limit.

The reporting limit is a property of the analytical method, not a regulatory pass/fail threshold. Different laboratories and methods may use different reporting limits. The result should always be read alongside the method reference and the laboratory that conducted the analysis.

What Does “Not Detected in 25g” Mean?

For Salmonella, the result is reported as Not detected in 25g rather than as a cfu/g count. This is standard practice for Salmonella testing under ISO 6579-1.

The ISO 6579-1 method tests a defined sample quantity — in this case 25 grams — for the presence or absence of Salmonella. “Not detected in 25g” means that Salmonella was not found in the 25-gram sample tested using this method.

This result applies to the specific sample quantity and method used. It does not mean Salmonella is definitively absent from every gram of every batch. It is a presence/absence result for the tested sample under the stated method conditions.

What Do These Tests Measure?

Coliforms

Coliforms are a group of bacteria used as hygiene indicators in food and supplement testing. Their presence can indicate inadequate processing or post-processing contamination. They are not all inherently harmful, but elevated counts are used as a signal that hygiene controls may need review. Tested here using ISO 4832.

Bacillus cereus

Bacillus cereus is a spore-forming bacterium found in soil and plant environments. It can produce toxins under certain conditions. It is tested in food and supplement products as a relevant indicator organism, particularly for products with plant or mineral origins. Tested here using ISO 7932.

Salmonella

Salmonella is a pathogenic bacterium associated with foodborne illness. It is a standard target in food and supplement microbiological testing. The ISO 6579-1 method is an internationally recognised presence/absence test applied to a defined sample quantity. Tested here in a 25g sample.

E. coli

Escherichia coli (E. coli) is tested as both a hygiene indicator and, in certain strains, a pathogen of concern. In food supplement testing, E. coli counts are used to assess the hygienic quality of the production process. Tested here using ISO 16649-2.

Aerobic Colony Count

The aerobic colony count (ACC) at 30°C measures the total number of aerobic microorganisms present in a sample under defined incubation conditions. It is a general indicator of overall microbial load and is used to assess the hygienic status of a product. Tested here using ISO 4833-1.

Microbiological Testing vs Heavy-Metal Testing

Microbiological testing and heavy-metal testing answer different analytical questions and are conducted by different laboratories using different methods.

• Bureau Veritas: Microbiological testing — organisms, hygiene indicators, pathogens
• Eurofins Scientific: Heavy metals (Lead, Arsenic, Cadmium, Mercury) and fulvic acid content

A microbiological report does not provide information about heavy-metal content. A heavy-metal COA does not provide information about microbial status. Both are separate, complementary analyses. For information on heavy-metal testing and regulatory limits, see: Heavy Metal Limits in Shilajit: EU, UK, USA & WHO Standards Explained and Heavy Metals in Shilajit: What Every Buyer Must Know.

How to Read a Microbiological Test Report

When reviewing a microbiological test report for a Shilajit product, the following fields should be clearly identifiable:

• Laboratory: The name and location of the accredited testing laboratory that conducted the analysis.
• Sample: The product or material that was tested.
• Batch: The specific production batch the sample was taken from. Results apply only to this batch.
• Method: The ISO or equivalent standard used for each test. Different methods have different detection sensitivities and reporting limits.
• Units: The unit of measurement for each result (e.g., cfu/g for colony counts; presence/absence for pathogens such as Salmonella).
• Result: The actual measured value or detection status. Read alongside the method and units.
• Sample quantity: For presence/absence tests such as Salmonella, the quantity of sample tested (e.g., 25g) is part of the result.
• Report date: When the analysis was completed and the report was issued.

The Golden Shilajit Bureau Veritas Report

The Bureau Veritas microbiological test report for batch SLJT01LQ is available to view on the Golden Shilajit Official lab reports page. The report includes the full test table, method references, report number, and laboratory details.

Batch-specific reports for both microbiological and heavy-metal testing are published here: Lab Reports & Certificate of Analysis. For a step-by-step explanation of how each batch moves from production to independent laboratory analysis, see: Our Testing Process →

What This Report Does Not Prove

Bottom Line

A useful microbiological test report identifies the batch, the laboratory, the method used for each test, the units, and the actual result — rather than relying on a generic “lab tested” claim. The Bureau Veritas report for batch SLJT01LQ documents five microbiological parameters using internationally recognised ISO methods. Results are batch-specific and should be read alongside the corresponding heavy-metal COA from Eurofins Scientific for a complete picture of the analytical testing conducted on that batch.
