Common Aflatoxin Test Testing Questions

Aflatoxins are tested using an LCMS/MS instrument. Instead of an overall Aflatoxin value, results for Aflatoxin B1, B2, G1, and G2 are individually reported.

Food manufacturers should be aware of aflatoxin regulations and guidelines since aflatoxins are potent carcinogens that impact human health and safety. The FDA also regulates aflatoxins.

Aflatoxins are not readily tastable or produce any aroma. Sometimes, the presence of visible mold or mold-like smell can be an indicator of aflatoxin contamination, but this would not be directly from aflatoxins.

Aflatoxins are most common in corn, wheat, rice, peanuts, tree nuts, straw, and sesame seeds. There are many foods that can be contaminated with aflatoxins since aflatoxins are produced by fungi species that are found across the globe and the environment.

While our sales and customer service team are happy to answer general testing questions, consultations typically start at a rate of $250 per 30 minutes regarding the interpretation of reported test results or questions about our test methods. We cannot consult on regulations, tolerance limits, or claims.

We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.

Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
