Food poisoning is a common reaction to toxins produced by bacteria. Those organisms thrive on food that is not prepared properly and stored for too long. Even coffee can cause food poisoning.

Orhratoxin A

Orhratoxin A is a mycotoxin produced by several fungal species. This can contaminate coffee from all over the world despite efforts to reduce the amount of mycotoxin in foods.


Ohraxotoxin is also a mycotoxin found in coffee that causes food poisoning. It is produced by penicillum and aspergillus, which are water soluble.


Ohratoxin spreads through high temperature and moisture, two key components in making coffee. However, although orhratoxin is present in coffee it usually only causes problems when coffee is stored in areas that are too hot.


Mytoxins are poisonous and cause a person to be nauseous, have diarrhea and vomit. These poisonous metabolites derive from molds and can cause pathological changes in humans.


Direct contamination of mycotoxins takes place when molds go directly onto food. This can directly affect coffee.

Avoiding Problems

To avoid food poisoning, be sure to prepare coffee as directed. The most important part of avoiding food poisoning from coffee is storing it at room temperature or cooler.
