01 · What we test

The food panel a retailer actually asks for.

Whole Foods, HEB, Costco, and the FDA all want the same data points on a food COA: actives, contaminants, and the metals/mycotoxins/pesticides the public press writes about. We test all of them on a single ticket.

01
LC-MS/MS

Pesticide residues

EPA / FDA-aligned 60+ analyte pesticide panel for produce, grains, and processed foods. Organophosphates, carbamates, neonicotinoids, pyrethroids, and the most-cited California and EU action-list residues.

LOD 5–10 ppb · 5–7 days
02
LC-MS/MS

Veterinary-drug residues

Antibiotic and growth-promoter residues in beef, pork, poultry, dairy, and eggs. Tetracyclines, sulfonamides, fluoroquinolones, beta-lactams, macrolides, plus beta-agonists (clenbuterol, ractopamine) and nitrofurans.

LOD 1 ppb · 5–7 days
03
LC-MS/MS

Mycotoxins

Aflatoxins B1/B2/G1/G2, ochratoxin A, deoxynivalenol (DON), zearalenone, fumonisins, T-2 / HT-2. Multi-residue panel for grains, nuts, dried fruit, dairy, animal feed, and brewing inputs.

LOD 0.5–1 ppb · 5–6 days
04
ICP-MS

Heavy metals — Closer to Zero

USP <232>/<233>-aligned panel for Pb, Cd, As (incl. inorganic arsenic speciation), and Hg. Tuned to FDA “Closer to Zero” action levels for baby food, juices, infant rice cereal, and seafood mercury.

LOD < 5 ppb · 4–5 days
05
LC-MS/MS

Adulterant & undeclared-ingredient screen

Melamine in dairy and protein matrices, nitrofuran metabolites in seafood, undeclared sweeteners, beta-agonists in meat. The FDA-warning-letter list — we run it before the importer or retailer asks.

LOD ppb · 5–7 days
06
Karl Fischer

Water content & shelf life

Karl Fischer moisture content and water activity for shelf-life modeling, packaging validation, and spoilage-risk classification. Pairs with the microbial / mycotoxin panel on stored grains and dried goods.

LOD 0.05 % · 2–3 days

03 · Common food failure modes

Where food product COAs fail.

These are the contaminants behind FDA recalls, retailer delistings, and class-action complaints in the last three years. Knowing where the risk concentrates is the first half of testing scope.

Inorganic arsenic
ICP-MS · ppb · juice / rice / cereal
High risk
FDA infant-rice-cereal action level 100 ppb. Apple, pear, and grape juice action level 10 ppb.
Lead (Pb)
ICP-MS · ppb · spices / cinnamon / juice
High risk
Spice-and-cinnamon recall driver in 2024-25 baby food puree market. ≤ 10 ppb is the action floor.
Cadmium (Cd)
ICP-MS · ppb · cocoa / leafy greens / shellfish
Medium risk
Chocolate, kale, spinach, and shellfish failure mode. Bioaccumulates from soil; impossible to spot-check at packaging.
Aflatoxin B1
LC-MS/MS · ppb · nuts / corn / dairy
High risk
Pre-harvest fungal toxin in peanuts, corn, tree nuts. Carries through into milk (M1) and pet food. EU action 2 ppb.
Glyphosate
LC-MS/MS · ppb · grain / oats / legumes
High risk
Pre-harvest desiccant residue in oats, wheat, lentils. EWG and class-action complaints concentrate here.
Chloramphenicol / nitrofurans
LC-MS/MS · ppb · shrimp / honey
Medium risk
Banned-substance imports from aquaculture and apiaries. FDA Import Alert 16-129 / 16-124 driver.
04 · Compliance

FDA, EPA, USDA, and FSIS — mapped to the COA.

Food testing is a mosaic of agencies. We map the assays directly to the regulation a retailer, importer, or auditor will cite.

FDA “Closer to Zero”
Heavy metals in baby food

FDA action levels for inorganic As (100 ppb infant rice cereal, 10 ppb juice), Pb (10 ppb juice, 20 ppb root vegetable baby food), Cd, and Hg under the Closer to Zero plan. Our ICP-MS panel reports against the published action floor.

21 CFR 109
Aflatoxin tolerances

FDA action level 20 ppb total aflatoxins for human food (0.5 ppb aflatoxin M1 in milk). EU action 2 ppb B1 / 4 ppb total. We report both bases on the COA so importer and domestic-buyer specs can both be met.

EPA tolerances
Pesticide residue limits

40 CFR Part 180 establishes commodity-specific pesticide tolerances. Our 60-analyte panel covers the most-cited residues with retest pricing for any out-of-tolerance hits.

USDA FSIS
Veterinary-drug residues

FSIS National Residue Program targets antibiotics, beta-agonists, hormones, and nitrofurans in domestic meat and poultry. Our panel mirrors the FSIS multi-residue method and reports in a format aligned to FSIS Form 10,800-1.

FDA / EU adulterants
Undeclared & banned ingredients

Melamine, sibutramine in weight-loss seasoning, undeclared sweeteners, banned dyes (Sudan I-IV). The watchdog list that triggers FDA import alerts and class-action lawsuits.

05 · Questions

Before you ship.

Still stuck? Email us — we reply within a business day.

Yes. Our ICP-MS heavy-metal panel is tuned to the FDA Closer to Zero action levels: 100 ppb inorganic As in infant rice cereal, 10 ppb As / 10 ppb Pb in juice, 20 ppb Pb in root-vegetable baby food. We can also run inorganic As speciation as an add-on rather than reporting total arsenic only.
