Peanuts are one of the highest-risk commodities for aflatoxin contamination. Our LC-MS/MS method quantifies B1, B2, G1, and G2 in peanut butter, flour, oil, and extracts.
Peanuts are the commodity most frequently associated with aflatoxin contamination in the US food supply.
Aspergillus flavus readily infects peanuts in warm, humid storage conditions.
FDA action level is 20 ppb total aflatoxins for peanut products. Our method detects at <0.5 ppb.
EU, Japan, and other export markets have stricter limits (2–10 ppb). We report against multiple thresholds.
Our LC-MS/MS method is validated for peanut and tree nut matrices including butter, flour, and oil.
One submission covers all four regulated aflatoxins.
Submitting takes less than 5 minutes. Most projects turn around in 5–10 business days from sample receipt.
Fill out our sample intake form — sample type, quantity, and timeline. We confirm turnaround and quote within one business day.
We'll send submission instructions and our San Diego shipping address. Most samples ship ambient or cold depending on stability requirements.
Results are delivered as a signed PDF COA within the agreed turnaround. Rush service (2–3 business days) available for urgent timelines.
Yes. Aflatoxins can partition into peanut oil, particularly crude or expeller-pressed oils. Our method is validated for oil matrices.
We use a solvent extraction protocol optimized for high-fat matrices like peanut butter to ensure accurate recovery.
Roasting reduces aflatoxin levels but does not eliminate them. Testing finished roasted products is still essential for FDA compliance.
Submit your samples and receive an ISO 17025 accreditation pending Certificate of Analysis. Results in 5–10 business days.
