The Need for Cannabis Decontamination
Let’s start with the obvious: cannabis is grown in soil, with the help of water and air—all of which
are teeming with microbes. While that’s not inherently bad, the wrong microbes, like mold or
bacteria, can sneak into your post-harvest product and create big problems. For growers, these
problems can prevent you from delivering a safe, reliable product worth the premium consumers
are paying.
Contaminated cannabis can fail mandatory microbial testing, sending entire batches to waste. In
Oregon, a recall involved nearly 23,000 cannabis products due to potential contamination—a
massive financial hit for producers. Mold is one of the biggest culprits, with strains like
Aspergillus capable of causing severe health issues, particularly for immunocompromised users.
California saw at least 13 recalls for Aspergillus contamination in early 2024 alone
Aside from recalls, contamination also impacts product quality. Mold doesn’t just lurk invisibly—it
can mess with your flower’s aroma, flavor, and appearance, all of which affect your bottom line.
And for consumers, there’s no faster way to lose trust than selling a product that feels, smells, or
tests unsafe.
This is why cannabis decontamination is such a crucial step in the manufacturing process.
Whether it’s through advanced decontamination technology or other cannabis remediation
techniques, addressing microbial load protects your product, your reputation, and your
business.
