Mycotoxins are contaminants that naturally occur in molds and fungi, which decompose organic matter. You can find molds that contain mycotoxins in a variety of crops such as nuts, spices, apples and coffee beans. You can also find mycotoxins in cannabis flower and its derivative products such as oils, edibles, tinctures and creams. Your hemp or cannabis products are especially at risk for mycotoxins in warm and humid environments. 


Mycotoxins can be very harmful to humans, especially in cases of long-term exposure so you want to be sure that your products are safe for use. Regardless of how carefully you produce and store your cannabis, or how much you trust your business partner’s cultivation methods–you can never be sure that your product is safe until you test with an accredited laboratory like ACS. 


What we test:

We test cannabis and hemp: Flowers/Plants, Derivative Products and Edibles

What we test for: 

We test for 5 analytes

Alfatoxins B1

Alfatoxins B2

Alfatoxins G1

Alfatoxins G2

Ochratoxin A

How we test:

We analyze flower, plants, derivative products and edibles for mycotoxins using the liquid chromatography–mass spectrometry LC/MS method. We extract the cannabis sample using a clean solvent, then quantify trace levels of mycotoxins using this standard testing protocol. We deliver precise results within 2-5 days. 

How to submit a sample for testing:

The process to submit a sample of your flower or product is easy. Plus, if you live in Florida, you can request our courier service from anywhere in the state. Simply request your test and we’ll review the submission process or arrange to collect a sample right away.  

Why it matters: 


Mycotoxins contain carcinogenic and mutagenic properties that can cause the development of cancerous cells and damage to the structure of your DNA. If your customers inhale or ingest compromised products, they can also become sick and nauseous. Nausea and vomiting are the precise symptoms that many medical cannabis patients seek relief from, so they need to be sure that your product is clean. Mycotoxin testing will guarantee that your hemp or cannabis products are safe and effective for consumption.



Currently there are no federal standards related to mycotoxin testing for cannabis because marijuana is still federally banned. Hemp however, is now legal and under review by the USDA and FDA for use in flower and consumer products. As soon as these rules are enacted, we will ensure that our testing protocol is fully compliant. 

At a state level in Florida, medical cannabis must be tested for contaminants such as mold, which may contain mycotoxins. Regarding hemp, Florida is also in the process of establishing rules via the state hemp CBD program. In that bill, the Florida senate proposed the following acceptable limits on the two major classes of mycotoxins: Aflatoxin and Ochratoxin.


Total Aflatoxin (B1, B2, G1, G2) =  20 parts per billion

Total Ochratoxin =  20 parts per billion


While states and the federal government continue to finalize laws, you want to be sure that your product is ready for retail. Moreover, your customers want proof that their hemp or cannabis product is free of this harmful toxin.
