Chất EO trong mì ăn liền gây hại ra sao mà nhiều nước cấm, VN thì không? | VOA

Summary

The VOA program examines concerns about ethylene oxide (EO) residues reported in Vietnamese instant noodles and other exported foods. The presenter says products have been recalled, returned, or flagged in some foreign markets, while Vietnam lacks a specific limit for EO residues in food. Food-science specialist Nguyễn Văn Tuấn discusses why residue levels and enforcement matter—not simply whether EO is used.

How EO May Enter Food

Tuấn describes EO as a gas used in various industries, including sterilization and pest control. He suggests residues may come from treated agricultural ingredients and spices, and raises the possibility of residues associated with packaging. These are presented as potential sources in the interview.

Regulation and Oversight

The guest says some countries set strict limits and monitor production, while Vietnam’s rules and enforcement are less developed. He argues that standards, inspections, production records, and penalties are needed to protect consumers. The program also notes that a residue used during production may not appear on an ingredient label.

Health Concerns and Uncertainty

The discussion describes EO as hazardous and carcinogenic, particularly in the context of substantial or prolonged exposure. Tuấn says consumers cannot identify EO by sight or smell, and that effects from food exposure would not necessarily be immediate.

He also acknowledges that there is no reliable figure for how much instant noodle consumption—or how long a person would need to consume it—to cause illness. The interview does not establish an individual’s risk from eating a particular product.

Practical Advice

Tuấn advises against relying on boiling or discarding noodle water to eliminate EO residues, which he says may be present in the food rather than simply as a gas. He recommends varying one’s diet and avoiding frequent, long-term reliance on any one food, while recognizing that consumers may have limited choices and that other foods can also contain residues.

Overall Conclusion

The speakers emphasize that consumers have limited ability to detect or avoid unlisted residues without reliable testing and disclosure. They call for stronger food-safety rules and enforcement, and urge consumers to pay attention to food quality and seek trustworthy information.
