Hidden Dangers of Wooden and Bamboo Chopsticks: Experts Warn of Cancer Risk
Many households still favour wooden or bamboo chopsticks, believing their textured surface offers better grip and prevents food from slipping. However, experts are now raising alarms about potential health hazards, especially when these chopsticks are reused or stored improperly.
According to Taiwan health advocate Tan Dunci, prolonged use of damp wooden or bamboo chopsticks can foster mould growth. Certain moulds produce aflatoxins, potent carcinogens that have been linked to liver cancer. Tan highlighted several tragic cases in China where entire families developed liver cancer, traced back to contaminated chopsticks.
She recommends switching to 304 stainless steel chopsticks, which are easier to clean and less likely to harbour dangerous mould. She stresses that chopsticks showing black spots or fuzz must be discarded immediately, as even seemingly clean surfaces can hide moisture in grooves that promote fungal growth.
Essential Chopstick Hygiene Tips
For those who prefer traditional wooden or bamboo chopsticks, Tan outlines three key care practices. First, wash each chopstick individually, following the grain to remove trapped debris. Avoid scrubbing the entire set together, which can push residue into cracks.
Second, after washing, store chopsticks in a well-ventilated area rather than upright in a chopstick holder. The bottom of the holder often stays damp, creating a perfect environment for mould. Third, periodically boil the chopsticks in hot water and use a drying machine to thoroughly remove moisture, reducing the risk of fungal contamination.
She also cautions that plastic or melamine chopsticks can release harmful substances if exposed to high heat, making them unsuitable for long-term daily use. In contrast, stainless steel and porcelain chopsticks, while slightly harder to handle, offer safer and more durable alternatives.
Medical Experts Weigh In
Gastroenterologist Dr. Xiao Dunren emphasises that chopsticks with grooves or textured ends are particularly prone to trapping food residues. These trapped particles can become breeding grounds for bacteria and fungi, potentially leading to serious health issues over time.
He urges regular inspection and timely replacement of chopsticks, pointing out that a seemingly minor kitchen item can have a significant impact on health. “It’s better to invest in safe chopsticks than risk ingesting harmful toxins that can lead to liver disease,” Dr. Xiao said.
With these simple but crucial practices, families can enjoy traditional dining safely while minimising hidden health risks. Choosing the right materials and maintaining proper hygiene can make everyday meals both enjoyable and safe.
