Study Report: Macroanalytical & Microanalytical Analysis of Parsley
In 2025, ASTA launched a collaborative study with FTS Laboratories and parsley suppliers to evaluate light filth and extraneous matter in parsley across a range of origins and grind sizes. The objective was to help inform potential cleanliness specifications for pre-processed parsley, given the absence of FDA Defect Action Levels (DALs) and existing ASTA Cleanliness Standards for this parsley. Samples were analyzed both macroscopically and microscopically for extraneous matter (ASTA Method 14.1) and light filth (AOAC Method 975.49).
