Popular Indian Spices Banned in Hong Kong Over Carcinogen Concerns: A Global Food Safety Alert

Popular Indian Spices Banned in Hong Kong Over Carcinogen Concerns: A Global Food Safety Alert

Reuters reported on April 27th, 2024, that the U.S. Food and Drug Administration (FDA) is monitoring the situation following Hong Kong’s ban on certain spice products from Indian companies MDH and Everest.

This ban stems from the detection of ethylene oxide, a carcinogenic pesticide, in these spices. The incident has sparked concerns about food safety standards and triggered investigations by regulatory bodies worldwide.

Ethylene Oxide: A Carcinogen Lurking in Spices?

Ethylene oxide (EtO) is a colorless gas commonly used as a disinfectant in industrial settings and for sterilizing medical equipment. However, it is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC) due to its link to an increased risk of various cancers, including lymphoma and breast cancer [1].

While EtO fumigation is not an approved practice for food in most countries, its residues can sometimes be found in spices due to post-harvest fumigation practices to eliminate pests and microorganisms.

Research on Ethylene Oxide and Health Risks

Multiple research papers published in renowned academic journals have investigated the health risks associated with EtO exposure. A 2020 study published in the International Journal of Environmental Research and Public Health examined the genotoxicity (ability to damage DNA) of EtO in human lymphocytes (white blood cells) [2]. The study found a significant increase in chromosomal aberrations in exposed cells, suggesting potential for EtO to initiate cancer development.

Another critical piece of research published in Occupational and Environmental Medicine in 2018 explored the association between occupational EtO exposure and various cancers [3]. This large-scale study found a positive correlation between EtO exposure and an increased risk of lymphohematopoietic malignancies (cancers of the blood and lymphatic system) in workers.

Regulatory Actions and Consumer Concerns

The recent spice ban in Hong Kong highlights the growing concern about EtO residues in food products. The permissible limits for EtO in food vary by country, with some having stricter regulations than others. Hong Kong’s Centre for Food Safety (CFS) detected EtO levels exceeding their safety standards in MDH and Everest spice mixes, prompting the ban to safeguard public health [4].

This incident has caused significant worry among consumers globally, particularly those who rely on these popular Indian spice brands. The potential health risks associated with EtO exposure, as evidenced by the aforementioned research, raise concerns about the long-term consequences of consuming contaminated spices.

The US Response and Global Implications

The FDA’s acknowledgement of the situation in Hong Kong indicates a potential for wider investigations and stricter regulations within the United States. The agency’s role is to ensure the safety of imported food products, and the presence of EtO residues in spices might warrant further scrutiny and potential import restrictions.

This incident also has global implications. Other countries with established food safety agencies are likely to review their regulations and testing procedures for imported spices. Increased international collaboration on food safety standards and stricter enforcement measures might be necessary to prevent similar incidents in the future.

The Road Ahead: Transparency, Improved Practices, and Consumer Confidence

The spice ban in Hong Kong serves as a wake-up call for the food industry. Spice companies like MDH and Everest need to implement stricter quality control measures to ensure their products are free from harmful contaminants like EtO. Transparency and clear communication with consumers regarding fumigation practices and potential risks are crucial for rebuilding trust.

Regulatory bodies worldwide should strengthen their testing protocols for imported food products to effectively identify and address potential contaminants like EtO. Additionally, fostering international cooperation on food safety standards and sharing best practices can help create a more robust global food safety system.

Consumers, meanwhile, can play a role by staying informed about food safety issues and familiarizing themselves with the permissible limits for various contaminants. Choosing reputable brands with a strong commitment to quality control can help minimize risks.



The recent spice ban in Hong Kong and the involvement of the FDA highlight the critical issue of EtO residues in food products. The potential health risks associated with EtO exposure necessitate stricter regulations, improved quality control practices within the food industry, and enhanced international cooperation on food safety standards. Regaining consumer confidence requires transparency from all stakeholders involved in the food supply chain. This incident presents an opportunity to strengthen food safety measures globally and ensure consumers have access to safe and healthy food products.
