Ethylene Oxide – Health Risks, Uses & Food Safety
Learn about ethylene oxide: industrial uses, health risks, and strict EU regulations on food contamination and monitoring.
Things worth knowing about "Ethylene oxide"
Ethylene oxide is a colorless, highly reactive gas widely used in the chemical industry.
Ethylene oxide is a key intermediate in the production of plastics, solvents, and surfactants. Because of its strong antimicrobial properties, it is also applied for sterilizing medical equipment and, in some countries, for fumigating food products.
However, ethylene oxide is extremely hazardous: even at low concentrations, it is carcinogenic and mutagenic. Acute exposure can cause irritation of the eyes, respiratory tract, and skin. Long-term exposure has been linked to an increased risk of leukemia and lymphoma, making it a major occupational hazard and environmental pollutant.
In the European Union, the use of ethylene oxide for food sterilization is banned. Strict regulatory limits are in place to monitor residues in foods such as sesame seeds, spices, and nuts. Recent international scandals involving contaminated products highlight the importance of rigorous food monitoring and transparent supply chains.
