mycotoxin
C2Scientific, Medical, Agricultural, Technical
Definition
Meaning
A poisonous substance produced by fungi (moulds).
A toxic secondary metabolite produced by organisms of the fungus kingdom, capable of causing disease and death in both animals and humans. Mycotoxins are particularly significant contaminants of food and feed, leading to significant economic losses and health concerns worldwide. They can be produced before harvest or during storage under specific environmental conditions.
Linguistics
Semantic Notes
The term is a compound of 'myco-' (meaning fungus) and 'toxin'. It is a hypernym for more specific toxins such as aflatoxin, ochratoxin, and fumonisin. It refers specifically to the toxic chemical, not the fungus producing it.

Examples
By CEFR Level
- Mould on food can make you sick. It makes a poison.
- Some types of mould produce dangerous poisons called mycotoxins.
- The presence of mycotoxins in nuts led to a major international food recall.
- Advanced chromatography techniques are essential for accurately quantifying mycotoxin contamination in agricultural commodities, as regulatory limits are extremely stringent.
Learning
Memory Aids
Mnemonic
Think: 'MY COat is TOXIC' because of the MOULD (fungus) growing on it. MY-CO-TOXIN.
Conceptual Metaphor
POISON AS A SECRETION (The fungus secretes its poison).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'грибной токсин' in a culinary sense; it specifically means 'токсин грибов/плесени'.
- Do not confuse with 'микотоксин' (direct cognate) or 'антибиотик грибкового происхождения' (e.g., penicillin).
Common Mistakes
- Mispronunciation: /maɪˈkɒtəksɪn/ (stress error).
- Using 'mycotoxin' to refer to the fungus itself, rather than the chemical it produces.
- Misspelling as 'mycotoxine' (adding an extra 'e').

FAQ
Frequently Asked Questions
No. Mycotoxins can be produced even when visible mould growth is not apparent, making them a hidden danger in food and feed.
Aflatoxin, produced by Aspergillus species, is one of the most potent and widely studied mycotoxins due to its carcinogenic properties.
Most mycotoxins are chemically stable and are not destroyed by normal cooking temperatures, which is why prevention of mould growth is critical.
No. Penicillin is an antibiotic produced by fungi. While technically a fungal metabolite, it is not classified as a mycotoxin because its primary effect on humans is beneficial, not toxic.
