EU found cancer-causing chemical in 527 Indian items

May 27, 2024

Between September 2020 and April 2024, food safety authorities in the European Union have found contamination in 527 products linked to India, most of them nuts and sesame seeds (313), herbs and spices (60), dietetic foods (48) and other food products (34). As many as 87 of the consignments were rejected at the border while many of the remaining were removed from the markets later.

Ethylene oxide (CAS 75-21-8), a colourless gas, is used as a pesticide and sterilising agent, though the chemical was originally intended to sterilise medical devices. Exposure to the ethylene oxide is said to cause lymphoma and leukemia among other cancers.

Data available from the Rapid Alert System for Food and Feed (RASFF), an online system that traces safety of food in the European Union member countries, shows the chemical was found in 525 food products and two feed products. While India was mentioned as the sole origin country for 332 of them, authorities tagged other countries where the chemical was found for the remaining products.

Jubin George Joseph, Chief Operating Officer, Ramaiah Advanced Testing Labs, said besides the direct exposure to ethylene oxide, consumers are susceptible to two more chemicals produced by the presence of the chemical in a food product.

“The most dangerous of these is ethylene glycol (CAS 107-21-1) whose presence in cough syrups led to deaths of children in Africa,” he said.

To a question, Jospeh said it is likely that ethylene oxide is widely used to sterilise products against salmonella and ecoli.

“Chemical treatment is the cheapest method available to keep the product longer on the shelf. Unfortunately, most of the countries do not test for the chemical, which will help us get a better picture,” he added.

The EU set 0.1 mg/kg limit following concerns over the chemical and its highly toxic breakdown products: 2-Chloroethanol (CAS 107-07-3) and ethylene glycol. In September 2021, the Spices Board had advised exporters to test for the same. However, considering that 121 contaminated products were detected in 2022 and 2023, Indian products had not yet met the quality mark.
