In a bizarre and hazardous new trend emerging on Mainland Chinese e-commerce platforms, decomposed citrus fruits covered in thick mold are being traded as high-value commodities. According to recent reports from local media, second-hand trading sites are hosting numerous listings for “moldy oranges,” with prices starting from double digits and reaching as high as 500 RMB (approximately HK$536) per individual fruit. While sellers justify these transactions by labeling the items as “scientific experiment materials,” medical professionals are issuing urgent warnings regarding the severe health risks associated with the trade and handling of these toxic specimens.
A Market for Mycotoxins
The trend centers on oranges that have reached advanced stages of decay, manifesting as dense patches of green, black, and white fuzz. Some listings specifically highlight the presence of Penicillium—the genus of mold used to produce penicillin—to attract buyers. However, the commercialization of household mold is a dangerous gamble. Sellers claim these fruits are ideal for biology or chemistry students, yet the lack of containment during shipping and handling poses an immediate threat to the public.
The Medical Verdict: Hidden Carcinogens
Family Medicine Specialist Dr. Cheryl Chan warns that these fruits are far more than just “spoiled produce.” According to Dr. Chan, moldy oranges can harbor dangerous mycotoxins, including Citrinin and Aflatoxin. The latter is a well-documented carcinogen. “Certain mold metabolites have been found to resist even high temperatures,” Dr. Chan explains, noting that long-term ingestion—even in trace amounts—can lead to chronic liver and kidney damage or increase cancer risks.
The dangers are not limited to consumption. Dr. Chan outlines several secondary risks for those handling these items:
- Respiratory Irritation: Inhaling airborne mold spores can trigger coughing, sneezing, and severe distress in individuals with asthma or weakened immune systems, potentially leading to fungal pneumonia.
- Dermal Reactions: Direct physical contact with mold patches can cause skin irritation, rashes, and allergic reactions.
- Acute Poisoning: Accidental ingestion—even a small amount—can result in nausea, vomiting, and diarrhea.
Safety Protocols for Biohazardous Waste
Health experts emphasize that moldy fruit should be treated as biohazardous waste rather than a collectible or a student resource. To prevent the accidental spread of spores, Dr. Chan advises the following:
- Direct Disposal: Do not attempt to save any part of a moldy fruit; seal it in a bag and discard it immediately.
- Protective Gear: If handling is necessary, wear gloves and a face mask to avoid inhalation and skin contact.
- Sanitization: Use diluted bleach or alcohol to disinfect any surfaces or tools that came into contact with the mold.
- Prevention: Store fresh produce in dry, well-ventilated areas to inhibit fungal growth.
While the “experiment material” market continues to fluctuate on digital platforms, the medical community remains firm: no scientific curiosity justifies the exposure to potent carcinogens. Consumers are urged to prioritize food safety over internet trends to protect their long-term health.
