What are mold toxins in coffee?

Mold toxins, also known as mycotoxins, are naturally occurring toxic compounds produced by certain molds that can grow on various agricultural products, including coffee beans. These toxins can develop in conditions of high moisture and poor storage, affecting the quality of the coffee. The most commonly discussed mycotoxin in coffee is ochratoxin A, which has been shown to have potential harmful effects on human health when consumed in significant amounts over time.

While the presence of mold toxins is a valid concern, it is essential to note that most reputable coffee producers implement rigorous quality control measures. These measures help minimize the presence of mold and mycotoxins in their products. Additionally, many studies suggest that the levels of mycotoxins, if present, often remain well below the thresholds considered harmful by health organizations.

How does mold get into coffee?

Mold can infiltrate coffee beans during various stages of the coffee production process, starting from the cultivation phase in the coffee farms to the post-harvest handling. High humidity and improper drying techniques can create an ideal environment for mold growth on the beans.
