Mycotoxins are toxic secondary metabolites which are secreted by fungi. They are often found on cannabis plants, released by fungi residing on the plant. High levels of mycotoxins in food and therapeutic products can be toxic and potentially fatal to consumers.

The maximum level of mycotoxins in medicinal cannabis products must comply with the limits specified in Schedule 1 of the TGO 93 Standard for Medicinal Cannabis. These limits are:

• 2 µg/kg of aflatoxin B1
