How to read a spice lab report

A laboratory report can look like a wall of abbreviations. Here is what the main sections mean, and what to look for when a spice brand says its products are tested.
1. Pesticide residues
Spices are agricultural crops, and many are grown with crop-protection chemicals. A multi-residue screen checks a sample for hundreds of possible pesticide compounds at once. Each result is compared against a Maximum Residue Limit (MRL): the highest level legally permitted in food for a given market.
Limits differ by country. India's limits are set by FSSAI; the European Union publishes its own, often stricter, limits. A useful report tells you which limits were applied, which compounds were found and at what level, and the laboratory's limit of quantification: the smallest amount it can reliably measure.
2. Heavy metals
Lead, cadmium, arsenic and mercury can enter food from soil, water or processing. Look for a result for each metal, the unit (usually mg/kg) and the applicable limit. Ground spices deserve particular attention, because grinding and colouring are where adulteration problems have historically occurred.
3. Mycotoxins
Mycotoxins are toxins produced by moulds when crops are dried or stored poorly. For spices such as chilli and nutmeg, the most important are the aflatoxins (B1 and total aflatoxins). Good drying and storage are the main defence; testing confirms they worked.
4. Microbiological safety
Because spices are often added at the end of cooking or eaten raw, their microbial load matters. Standard checks include total plate count, yeast and mould, and the absence of pathogens such as E. coli and Salmonella.
5. Product integrity and quality
The final section is about how good the spice is, not only how safe. Typical parameters include moisture, volatile oil content (the aromatic oils that carry flavour), colour and product-specific markers such as curcumin in turmeric or piperine in pepper.
What to ask any spice brand
- Was the test done by an independent, accredited laboratory?
- Does the report relate to the batch you are buying, or to a single sample from years ago?
- Which limits (India, EU or others) were the results compared against?
- Can you see the report, not just a badge on the pack?
These are the questions we built Van Rasoi around. Every pack carries a batch code, and you can look up its record, or request its report, on our Batch Passport page. Read more about our quality standard.
