The common toxins include:
- Aflatoxin
- Ochratoxin A (OTA)
- Deoxynivalenol (DON)
- Fumonisin
- Zearalenone
These toxins can cause:
- Cancer (especially aflatoxin)
- Liver and kidney damage
- Immune suppression
👉 This is precisely why countries and international organizations have issued Maximum Levels (MLs) to ensure food safety and international trade.
1. Mycotoxin limit regulations in Vietnam
In Vietnam, mycotoxin regulations are issued mainly in standards such as:
- QCVN 8-1:2011/BYT (limits of toxin contamination in food)
- MARD regulations for animal feed
* Some representative limits:
Aflatoxin (total B1, B2, G1, G2):
- Cereals: ≤ 15 µg/kg
- Children's food: ≤ 5 µg/kg
Aflatoxin M1 in milk:
≤ 0.5 µg/kg
Ochratoxin A:
Cereals: ≤ 5 µg/kg
👉 In general, Vietnam applies limits fairly similar to Codex but can be flexible per product group.
2. Mycotoxin regulations in the European Union (EU)
The EU is rated as the region with the strictest standards in the world for mycotoxins.
Main regulation: EC Regulation No. 1881/2006
* Representative limits:
Aflatoxin B1:
- Cereals: ≤ 2 µg/kg
- Total aflatoxin: ≤ 4 µg/kg
Aflatoxin M1 (milk):
≤ 0.05 µg/kg (very low)
Ochratoxin A:
Cereals: ≤ 3–5 µg/kg
DON (Deoxynivalenol):
- Wheat: ≤ 1250 µg/kg
👉 The EU demands extremely strict limits because:
- Protecting consumer health
- Controlling imported goods
➡️ This is why many export shipments from Vietnam are returned for exceeding mycotoxin thresholds.
3. FDA mycotoxin regulations (USA)
- Regulator: U.S. Food and Drug Administration
- The FDA does not use "maximum limits" like the EU but uses:
👉 Action Levels
* Some representative levels:
Total aflatoxin:
- Food: ≤ 20 µg/kg
Aflatoxin M1 (milk):
≤ 0.5 µg/kg
DON (vomitoxin):
Food: ≤ 1000 µg/kg
Fumonisin:
- Corn: ≤ 2000–4000 µg/kg
The FDA monitors closely through food and feed inspection programs.
👉 Compared with the EU:
- The FDA is more flexible
- The EU is significantly stricter
4. Quick comparison of mycotoxin limits in Vietnam – EU – FDA
👉 Conclusion:
- The EU is the strictest → high requirements for export
- The FDA is flexible → suited to the US market
- Vietnam is in between
5. The impact of mycotoxin regulations on businesses
Food & feed businesses need to note:
⚠️ Risks if not controlled:
- Returned shipments
- Loss of brand reputation
- Major financial damage
✅ Solutions:
- Test incoming raw materials
- Apply rapid mycotoxin tests
- Confirm with HPLC / LC-MS/MS
- Comply with export market standards
6. Future trends in mycotoxin management
- Standards will be even stricter
- More control across the supply chain
- Applying rapid tests & PCR for early detection
- Alignment with Codex & WHO
Conclusion
The mycotoxin limit regulations in Vietnam, the EU, and the FDA differ clearly, especially as the EU has very high standards.
👉 Businesses
- Understand each market's regulations.
- Control mycotoxins from the very start.
- Use suitable testing solutions.
