Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general 'токсин' (toxin) – specify 'афлатоксин' as it's a direct loanword.
- Avoid translating as 'плесневый яд' unless explaining broadly; the scientific term is standard.
Common Mistakes
- Misspelling as 'aflotoxin' or 'aflatoxine'.
- Using as a countable plural ('aflatoxins') when referring generally to the contamination issue ('aflatoxin contamination').

Yes, it is potently toxic and carcinogenic, especially to the liver. It can cause acute poisoning and is linked to liver cancer.
No, aflatoxin is heat-stable; normal cooking, roasting, or boiling does not effectively destroy it.
Through good agricultural practices, proper drying and storage of crops, and regular laboratory testing to enforce regulatory limits.
