Pesticide Residue Testing
Laboratory analysis of pesticide residues in food products
Pesticide Residue Testing is the laboratory analysis of food samples to detect and quantify pesticide active substances and their metabolites. Testing ensures compliance with Maximum Residue Limits (MRLs) set by importing countries.
Testing methodologies: - **Multi-residue methods** (LC-MS/MS, GC-MS/MS): screen 200-500 active substances simultaneously. Standard for routine compliance testing. - **Single-residue methods**: targeted testing for specific compounds (glyphosate, dithiocarbamates). - **QuEChERS extraction**: standard sample preparation method.
For Egyptian fresh produce exports to the EU, pesticide testing is the single most important pre-shipment quality control activity. Key concerns: - EU MRLs are stricter than Codex MRLs for many active substances. - Some active substances banned in EU may still be used in Egypt (carbendazim, paclobutrazol). - Detection limits are very low (often 0.01 mg/kg LOQ). - Testing turnaround: typically 3-5 working days.
Sampling considerations: - ISO 2859 sampling plans for multi-pallet shipments. - Composite sampling per Commission Directive 2002/63/EC. - Sample aliquots split for laboratory + retain.
FoodGate Audit arranges pesticide residue testing via accredited laboratories (Egypt and Europe). We conduct sampling at packhouses, ship to laboratories, and provide certified reports compliant with EU MRL frameworks.
