Contaminants and Residue Analysis

Contaminant and residue analysis is a critical component of food safety and regulatory compliance. It supports risk management throughout the food supply chain, from raw materials to finished products. Contaminants and residues may arise from agricultural practices, processing aids, packaging materials, environmental exposure, or cross-contamination during production.

Our analytical services cover a wide range of chemical contaminants, including emerging contaminants, metals, food additives, veterinary drug residues, and pesticide residues. Testing strategies are selected based on applicable regulatory requirements and risk assessment principles to ensure reliable and fit-for-purpose results for food safety evaluation and market compliance.

PFAS (Per- and Polyfluoroalkyl Substances)

PFAS are globally recognized emerging contaminants due to their environmental persistence and potential for bioaccumulation within the food chain. Monitoring PFAS is increasingly required for export markets and regulatory compliance.

Analysis is performed using high-sensitivity LC-MS/MS, enabling detection at very low concentration levels. Testing is available for food products, water, and production-related samples.

Minerals and Heavy Metals

Mineral and heavy metal analysis plays an essential role in evaluating both food safety and nutritional quality. Elements may naturally occur in raw materials or be introduced through environmental contamination, processing, or handling.

Testing is conducted using advanced elemental analysis techniques such as ICP-MS and ICP-OES, in accordance with internationally recognized methods including AOAC, US EPA, ISO, and peer-reviewed references.

Scope includes:
  • Nutritional and quality-related minerals such as Calcium, Magnesium, Iron, Zinc, Sodium, and Potassium
  • Heavy metals and toxic elements including Lead, Cadmium, Mercury, Arsenic, and other regulated metals

Food Additives and Veterinary Drug Residues

Analysis of food additives and veterinary drug residues is essential to verify compliance with regulatory limits and ensure product safety.

Testing is performed using HPLC and LC-MS/MS, supporting both targeted analysis and multi-residue screening.

Scope includes:
  • Regulated food additives and preservatives
  • Antibiotics and antimicrobial agents
  • Anthelmintics and veterinary drugs
  • Histamine
  • Illegal dyes

Pesticide Residue Analysis

Pesticide residue testing is a key component of food safety systems, particularly for agricultural commodities, raw materials, and processed food products intended for domestic and export markets.

Testing supports verification of compliance with country-specific regulatory requirements, including Maximum Residue Limits (MRLs) established by national and international authorities.

Residues may originate from agricultural chemical use, environmental contamination, or post-harvest handling. Systematic analysis supports raw material screening, quality control, and risk management across the supply chain.

Our services cover vegetables, fruits, cereals, raw materials, processed foods, and related products. We offer both:

  • Multi-Residue Analysis
  • Single Residue Analysis

    • Testing is performed using advanced GC-MS/MS and LC-MS/MS technologies, enabling detection at low concentration levels across multiple pesticide classes in a single analytical run.

    Major pesticide groups covered include:
    • Carbamates
    • Organochlorines
    • Organophosphates
    • Pyrethroids

    Additional pesticide groups are included under comprehensive multi-residue screening and specific targeted testing according to destination market requirements.
