Critical Food Contaminants Testing: Metals & Pesticides

Food contaminants testing is a critical component of safety plans under FSMA and FDA regulations. Heavy metals in food—like Lead, Cadmium, Arsenic, and Mercury—pose significant toxicity risks, while pesticide residues must remain within strict EPA tolerances.

AGT Labs utilizes state-of-the-art Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for trace metal detection and advanced LC-MS/MS platforms for identifying pesticides in food products, ensuring your brand meets the highest safety standards.

Why Contaminant Testing Matters

Protecting public health and avoiding regulatory action through precise chemical contaminant analysis.

1. Consumer Safety

Protect vulnerable populations, especially infants, from the neurotoxic effects of heavy metals and long-term pesticide exposure.

2. Regulatory Action

Avoid FDA Import Alerts and "Detention Without Physical Examination" (DWPE) by proving compliance with action levels for food contaminants.

3. Supply Chain Verification

Validate the purity of raw ingredients before they enter your production line, preventing pesticides in food products.

Heavy Metals Testing

Heavy Metals Testing

Manufacturers are under increasing pressure to meet the FDA's "Closer to Zero" targets for toxic elements. Our heavy metals testing services achieve parts-per-billion (ppb) sensitivity, essential for assessing risk against California Proposition 65 Safe Harbor Levels.

The "Big Four" Analytes

Lead (Pb), Cadmium (Cd), Arsenic (As), Mercury (Hg). We detect these heavy metals in food along with Chromium and Nickel upon request.

Speciation Capabilities

Total Arsenic screening often yields false alarms. We perform Arsenic Speciation Analysis to distinguish toxic Inorganic Arsenic from harmless organic forms commonly found in seafood.

Test Methods

ICP-MS per AOAC 2015.01 or FDA EAM 4.7.

Pesticide Residues Analysis

Pesticide Residues Analysis

Modern retailers demand "Clean Label" transparency regarding pesticides in food. We help you navigate the complex landscape of MRLs (Maximum Residue Limits) for global export markets, ensuring your products are free from harmful pesticide residues.

Multi-Residue Screen

Our comprehensive screen covers 400+ compounds including Organophosphates and Pyrethroids. We utilize the QuEChERS method for high recovery rates of pesticide residues.

Organic Verification

Verify your USDA Organic status by screening for prohibited synthetic substances. We also offer assays for polar pesticides like Glyphosate (Roundup).

Test Methods

LC-MS/MS and GC-MS/MS per AOAC 2007.01.

Verifying purity in dried ingredients prone to heavy metal accumulation.

Technical Capabilities

Advanced analytical platforms designed to detect food contaminants at the lowest limits required by today's regulations.

Trace Analysis Equipment
  • ICP-MS Technology (Agilent 7900)

    Our Inductively Coupled Plasma Mass Spectrometer is the gold standard for trace metal analysis. It allows us to detect heavy metals in food at parts-per-trillion (ppt) levels, far exceeding the sensitivity of standard atomic absorption.

    Low Detection Limits • Rapid Throughput • Broad Dynamic Range

  • LC-MS/MS & GC-MS/MS (Triple Quadrupole)

    We employ tandem mass spectrometry coupled with both Liquid and Gas Chromatography. This dual approach ensures comprehensive coverage of pesticide residues across polar and volatile compound groups.

    Multi-Residue Screen • Matrix Filtration • High Selectivity

  • Methodology & Validation

    All methods in food contaminants are validated against AOAC and FDA PAM guidelines. We utilize QuEChERS extraction protocols to maximize analyte recovery while minimizing waste for complex food matrices.

Common Questions About Contaminant Testing

What heavy metals should be tested in food?
The "Big Four" toxic heavy metals that are most commonly regulated and tested for are Lead (Pb), Cadmium (Cd), Arsenic (As), and Mercury (Hg). These pose the most significant health risks and are the focus of FDA and international standards.
How do you test for pesticide residues in food?
We utilize a multi-residue screening approach using LC-MS/MS and GC-MS/MS. This allows us to detect and quantify hundreds of different pesticide compounds (insecticides, herbicides, fungicides) in a single analysis with high sensitivity.
What are the FDA limits for heavy metals in food?
Limits vary significantly by product type. For example, the FDA has specific action levels for lead in fruit juices and candy, and arsenic in rice cereals. We verify your products against specific FDA Action Levels, EU Regulations, or Prop 65 safe harbor levels.
Why is arsenic speciation analysis important?
Total arsenic testing does not distinguish between organic arsenic (often non-toxic, found in seafood) and inorganic arsenic (highly toxic, found in rice/water). Speciation analysis separates these forms to determine the actual toxicity risk of your product.
Do you test for glyphosate (Roundup) residues?
Yes, Glyphosate is a polar pesticide that requires a specialized extraction method different from standard multi-residue screens. We offer specific testing for Glyphosate and its metabolite AMPA to verify organic or residue-free claims.
What is California Proposition 65 (Prop 65) compliance?
Prop 65 requires businesses to provide warnings about significant exposures to chemicals that cause cancer or birth defects. We test for heavy metals and provide data to help you determine if your product meets the "Safe Harbor Levels" (No Significant Risk Levels) to avoid warning labels.
