We use methods validated by the American Spice Trade Association (ASTA) and perform nut, seasoning, and spice analysis in ISO 17025 accredited and USDA approved labs. With more former FDA personnel than any other laboratory testing company, we provide experience with FDA imports and Detention Without Physical Examination to help get your shipment released quickly. In addition, we strive to start all microbiological samples on the day of receipt, ensuring industry-leading turnaround time.

All Your Spice Analysis Performed in One Laboratory

We offer several test matrices and a broad portfolio of assays for spice analysis. This allows you to perform all your testing at one laboratory for maximum convenience. Our seasoning and spice analysis capabilities include the following:

Microbiology Analysis for Spices and Seasonings

Operating a microbiological testing department since our founding in 1926 has allowed us to develop deep expertise with respect to pathogens and microorganisms that can negatively affect the spice and seasoning industry. Our spice analysis capabilities include the following:

  • Salmonella
  • Listeria
  • E. coli O157:H7
  • Staphylococcus & its Enterotoxin
  • Environmental Monitoring
  • Shelf-Life Studies
  • Challenge Studies
  • Process Validation
  • Real-Time PCR
  • Phage Technology
  • Genetic Strain Typing

We use state-of-the-art equipment and current methods as promulgated by the AOAC, BAM, Compendium of Methods, and others as appropriate. In addition, we strive to start all microbiological samples on the day of receipt, ensuring industry-leading turnaround time.

Light Filth/Microscopic Analysis

With the increased importation of ground spices and the need to evaluate other commodities for filth, we use micro-analytical techniques. By using separation techniques and skilled element identification, a great deal can be discovered about the conditions under which your products were held and produced, providing you with the accurate, consistent data you need to make good business decisions.

Sanitation/Macroscopic Analysis

Extraneous matter (“filth”) in spices can be described as the extraneous matter left behind by product contaminants. It includes whole insects, excreta, rodent hairs, and feather barbules.

Certified Laboratories stays current with changing FDA methodology and Defect Action Levels (DALs), enabling us to tell you quickly and accurately whether your shipment will pass the rigid FDA and ASTA spice standards established for “filth”.

The American Spice Trade Association (ASTA) sanitation program also includes testing of oregano for sumac and other adulterants. We are proud to have been part of the working group that established and validated the current method for ASTA.
