Why Pesticide Testing Is Critical
Pesticide residues are a growing concern for consumers and regulators. Botanical ingredients, teas, grains, and plant-based oils are particularly prone to contamination. Without proper pesticide testing, brands risk regulatory violations, import bans, or labeling noncompliance — especially in organic and health-focused sectors.
What We Test For
We offer comprehensive pesticide residue testing for over 400 active substances, including organophosphates (chlorpyrifos, malathion, diazinon), organochlorines (DDT, endosulfan, lindane), carbamates, pyrethroids (permethrin, cypermethrin), neonicotinoids, and glyphosate.
Testing Methods
We use GC-MS/MS and LC-MS/MS for multi-residue pesticide screening, following USP <561>, EPA, EU Annex II, and AOAC 2007.01 methods. Limit of detection (LOD) and limit of quantification (LOQ) data are provided with every report.
