Technical Testing Parameters
The following parameters describe product-specific testing considerations. Test availability, method suitability and accredited coverage are confirmed against the sample and specification before quotation.
- Quality: pH; titratable acidity; soluble solids (°Brix); moisture; ash; salt; sulphur dioxide where used; benzoic acid and sorbic acid where permitted.
- Microbiology: aerobic colony count; yeast and mould; Escherichia coli; Salmonella spp.; Listeria monocytogenes for relevant ready-to-eat produce; commercial sterility for applicable retorted products.
- Residues: commodity-specific LC-MS/MS and GC-MS/MS pesticide panels; examples include chlorpyrifos, imidacloprid, acetamiprid and carbendazim. Scope must match the crop and market; use a separately suitable method for glyphosate if required.
- Contaminants and toxins: lead; cadmium; arsenic as prescribed; Aflatoxin B1 and total aflatoxins for susceptible nuts/seeds; ochratoxin A where relevant; patulin for relevant apple products; cyanogenic compounds for appropriate matrices.
Select the applicable subset; these are not universal mandatory tests or a statement that every listed test is within the laboratory’s accredited scope.
Regulatory Standards & Compliance
Product mapping: 2.3; use 2.4 for relevant dry pulse products and 2.16 for hemp products.
Read the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011 as amended, together with the product-specific criteria. Apply the current Contaminants, Toxins and Residues Regulations, 2011 and Labelling and Display Regulations, 2020 where relevant.
For microbiology, identify the applicable Appendix B table, sampling plan and test portion. For additives, confirm the correct Appendix A classification and any product-specific restrictions. FoSCoS licensing identifiers are not equivalent to product-standard clauses.
Export limits depend on the destination, commodity and residue definition. Confirm the applicable MRL, reporting limit and effective date. BIS product standards, export certification and laboratory recognition require separate verification; a test report does not itself confer regulatory approval.
Sample Requirements & TAT
Separate lots and matrices; chill fresh-cut produce; maintain frozen products frozen. Mycotoxin sampling may require substantially larger incremental and aggregate samples.
Confirm the required quantity, number of unopened units, containers and transport conditions with the laboratory before dispatch. Chemistry portions and sterile microbiology portions may need separate containers; a composite cannot automatically replace an n-unit sampling plan.
Provide the product designation, ingredient list, processing state, batch identity, storage instructions, target market and required specification. Turnaround is confirmed in the quotation after the scope is agreed. Shelf-life, challenge and specialist investigations require a separate study schedule.
Technical FAQs
Does a broad pesticide screen cover every export residue?
No. Obtain the crop, destination and buyer list, then match analytes, residue definitions and reporting limits to the required panel.
Why can two nut samples give different aflatoxin results?
Contamination can be highly heterogeneous. The lot-sampling and homogenisation procedure is as important as instrumental analysis.
Can fresh and canned vegetables share one microbiological specification?
No. Intended use, heat treatment, packaging and the applicable product table determine the criteria.
