Why Golden Shilajit Uses Two Independent Labs: What Eurofins and Bureau Veritas Each Test, and Why Both Matter

Written by Ayesha Rahman — Lab Assistant, Golden Shilajit Official Research Team. Reviewed by the Golden Shilajit Research Team.

Laboratory Testing — 2026

Most supplement brands name one laboratory in their marketing. Golden Shilajit Official uses two — and the distinction is not cosmetic. Eurofins Scientific and Bureau Veritas serve different testing functions, using different methods, on different parameters. Understanding what each laboratory does, and why both are part of the testing programme, is the most direct way to evaluate what the results actually mean.

This article explains the role of each laboratory, the difference between chemical and microbiological testing, and what the results recorded for batch #SLJT01LQ show. All figures cited here are drawn from the published laboratory reports and site content. For the full reports, see the Lab Reports page.

Question 1 of 10

What is Bureau Veritas and why is it used for Shilajit testing?

The Bureau Veritas laboratory in Dubai, UAE conducted the microbiological analysis of Golden Shilajit batch SLJT01LQ. The results are documented in a formal report issued by that laboratory.

For Shilajit specifically, microbiological testing matters because raw Shilajit is collected from mountain rock faces and is exposed to environmental microorganisms during collection. Even after purification, a finished product requires independent testing to document the microbiological status of the batch. Bureau Veritas conducted that testing for batch SLJT01LQ.

Question 2 of 10

What is the difference between microbiological and chemical testing in Shilajit?

Chemical testing produces quantitative results: a percentage figure for fulvic acid content, or a measured concentration for each heavy metal. The question it answers is: what is in this product, and at what level?

Microbiological testing looks for the presence of specific organisms. It answers a different question: are specific microbial indicators or pathogens detectable in this product at the time of testing? The parameters tested are microbial indicators and specific pathogens.

The distinction matters for a practical reason: a product can have well-documented chemical results and still have microbiological indicators recorded at different levels, because the two types of testing measure different things. Chemical and microbiological testing are complementary, not interchangeable.

Question 3 of 10

Why use separate labs for chemical and microbiological testing?

Chemical testing of heavy metals by ICP-MS (Inductively Coupled Plasma Mass Spectrometry) uses different instrumentation and procedures from microbiological testing, which requires incubation, growth media, and protocols designed to detect biological organisms. These are not the same analytical environment or the same methodological framework.

The more relevant point for buyers is what the two reports together cover: chemical composition parameters from Eurofins, and microbiological parameters from Bureau Veritas — both documented independently, on the same batch, in separate laboratory reports.

Question 4 of 10

What does the Bureau Veritas microbiological panel test for?

The five parameters and what they represent:

• Coliforms (ISO 4832) — a group of bacteria used as indicators in microbiological testing of food and supplement products.
• E. coli (ISO 16649-2) — Escherichia coli; a specific bacterium tested as a microbiological indicator.
• Salmonella (ISO 6579-1) — a pathogen tested by presence/absence determination in a defined sample size.
• Bacillus cereus (ISO 7932) — a spore-forming bacterium included as a standard parameter in microbiological testing of food and supplement products.
• Aerobic colony count @30°C (ISO 4833-1) — a count of aerobic bacteria grown at 30 degrees Celsius, used as a general microbiological measurement.

The lab report page also notes that the Bureau Veritas report includes sensory analysis and additional screening; those parameters are not individually listed in the published summary.

Question 5 of 10

What does “Aerobic colony count @30°C” mean?

The term is broken down as follows:

• Aerobic refers to organisms that require oxygen to grow. The test incubates the sample in conditions that allow oxygen-dependent bacteria to form countable colonies.
• Colony count refers to the number of colony-forming units detected. Each colony represents bacteria that grew from an organism or cluster present in the sample.
• @30°C specifies the incubation temperature. 30°C is the temperature specified for this measurement under ISO 4833-1.

This parameter is one of five recorded in the Bureau Veritas report for batch SLJT01LQ. The recorded result was <10 cfu/g.

Question 6 of 10

What does “<10 cfu/g” mean on a Shilajit report?

The unit cfu/g stands for colony-forming units per gram. It is the standard unit for expressing microbial counts in solid or semi-solid products. One colony-forming unit corresponds to a single bacterium or cluster of bacteria capable of growing into a visible colony under laboratory conditions.

The “<” symbol means “less than.” A result expressed as “<10 cfu/g” indicates the count was recorded as less than 10 for that parameter.

Salmonella was reported using a different format — “Not detected in 25g” — because pathogen testing for Salmonella under ISO 6579-1 is conducted as a presence/absence determination in a defined sample size, not as a colony count.

In the Bureau Veritas report for batch SLJT01LQ, the recorded results were:

• Coliforms: <10 cfu/g
• Bacillus cereus: <10 cfu/g
• E. coli: <10 cfu/g
• Aerobic colony count @30°C: <10 cfu/g
• Salmonella: Not detected in 25g

Question 7 of 10

What was Eurofins used to test in this Golden Shilajit batch?

Eurofins Scientific holds ISO/IEC 17025 accreditation. For Golden Shilajit batch #SLJT01LQ, Eurofins was used for two specific test categories:

Fulvic acid content — Fulvic acid content is one of the measured composition parameters reported for the tested batch. Eurofins measured the fulvic acid content of batch #SLJT01LQ. The recorded result was 45.39 g/100g (45.39%).

Heavy metals — Eurofins tested Lead, Arsenic, Cadmium, and Mercury using ICP-MS (Inductively Coupled Plasma Mass Spectrometry). The specific numerical results for each metal are documented in the COA. For a detailed discussion of heavy metal testing in Shilajit, see: Heavy Metals in Shilajit: What Every Buyer Must Know.

Question 8 of 10

Can Shilajit have strong chemical results and still have microbiological indicators recorded at different levels?

Chemical testing documents composition parameters — what compounds are present and at what measured level. Microbiological testing documents whether specific organisms or pathogens are detectable in the product at the time of testing. These are different questions, answered by different methods.

Purification removes impurities from the raw material, but chemical results from before or during purification do not describe the microbiological status of the finished product. Post-purification handling, filling, and packaging all represent separate stages where conditions differ from the purification process itself.

The reverse also holds: microbiological results tell you nothing about heavy metal levels or fulvic acid content. Chemical and microbiological testing provide complementary information about different tested parameters. For batch #SLJT01LQ, these two testing roles were carried out by Eurofins Scientific and Bureau Veritas.

Question 9 of 10

What do the actual batch #SLJT01LQ lab results show?

The following is a factual summary of the documented results for batch #SLJT01LQ:

The heavy metal values for Lead, Arsenic, Cadmium, and Mercury are documented in full in the Eurofins COA, available on the Lab Reports page as a published document. All results are batch-specific. Results from batch #SLJT01LQ apply to that production run only and should not be assumed to represent another batch.

Question 10 of 10

How should buyers compare two-lab testing between Shilajit brands?

A brand that references “third-party tested” in its marketing without publishing the reports provides no verifiable information. A brand that publishes COAs but does not name the laboratory provides limited verifiable information. A brand that publishes named, batch-specific reports across multiple testing categories allows buyers to review the scope and specifics of what was tested.

When reviewing any brand’s testing claims, apply these questions:

• Is the laboratory named? Is it independently accredited?
• Does the report cover both chemical parameters (heavy metals, fulvic acid) and microbiological parameters?
• Is the report tied to a specific batch number that matches the product currently being sold?
• Are the actual reports available to view — not just a summary or marketing claim?
• Are the results presented as measured values, or only as “pass” statements without underlying data?

Testing from two laboratories covering separate analytical categories provides information across more than one testing category. The value is in what was tested, by whom, on which batch, and whether the reports are available for direct review.
