At Toomer’s Coffee Roasters, all of our coffees are 3rd party tested because we know our customers care deeply about both the quality and safety of what’s in their cup. In recent years, certain coffee brands have begun marketing their products as “mycotoxin-free” or “third-party tested for mold toxins,” often raising more questions than answers…

…but here’s the truth

So—are mycotoxins a legitimate concern? Should you be seeking out “clean” coffee? And what do these buzzwords actually mean?

Let’s take a calm, evidence-based look at the facts to help you enjoy your coffee with confidence.

What Are Mycotoxins?

Mycotoxins are naturally occurring compounds produced by molds such as Aspergillus and Penicillium. These can develop in improperly stored crops like grains, nuts, and green (unroasted) coffee beans. In coffee, the most discussed mycotoxin is ochratoxin A (OTA).

Regulatory agencies including the FDA and European Food Safety Authority (EFSA) have studied OTA extensively and set safe consumption limits — far below any levels found in properly processed and roasted coffee.

Are Mycotoxins New or Caused by Chemicals?

No. Mycotoxins are not synthetic pesticides or modern agricultural additives — they’ve existed as long as farming has. They are a byproduct of nature when food is poorly stored in warm, humid conditions.

Thanks to better modern drying, storing, and roasting techniques, high-quality specialty coffees like ours at Toomer’s are extremely low-risk for mycotoxins.

Do Mycotoxins in Coffee Pose a Real Health Risk?

Not realistically. Research has shown that an adult would need to consume over 7,000 cups of coffee per day at the legal maximum OTA level to approach harmful thresholds.

Roasting coffee beans destroys 70%–90% of any present OTA, and brewing dilutes it further. In fact, a 2020 EFSA study confirmed that most brewed coffee contains levels so low they are undetectable or far below safety limits.

So What Does “Third-Party Tested” Really Mean?

Good question.

✅ Some companies hire private labs to test for mycotoxins.

🟡 But the FDA and USDA already regulate all imported coffee, and green beans are routinely tested or monitored for mold and contaminants.

So when a brand says “third-party tested”, it may imply more than it delivers — because virtually all coffee in the U.S. is already regulated and inspected by third parties through federal oversight.

So What About “Mycotoxin-Free” Coffee?

The phrase or term “mycotoxin-free” isn’t regulated by the FDA, and in most cases it means the coffee tested below detectable limits, which is already the norm for any well-produced, properly roasted specialty coffee.

⭐️ In other words, “mycotoxin-free” is often a marketing term, not a health breakthrough.
