Stop Just Rinsing Your Thermos with Water! Doctor Reveals the Correct Cleaning Method—Mistakes Could Make You Ingest Mold and Toxins

A health-conscious elderly man with an extremely disciplined lifestyle, abstaining from smoking and alcohol while maintaining regular exercise, was diagnosed with advanced liver cancer during a routine health checkup and unfortunately passed away. While sorting through his belongings, his family opened the thermos he had used daily and were shocked to discover severe mold growth inside the bottle and silicone lid, uncovering a hidden cancer risk!

Gastroenterologist Dr. Chien Cheng-Hung and 'Mother of Non-Toxic Living' Tan Dun-Tzu jointly warn that many people overlook a 'crucial step' after washing their thermos, allowing moisture to remain trapped inside, creating a breeding ground for mold and toxins. Long-term ingestion of these highly toxic mold byproducts could cause irreversible and severe damage to liver and kidney health.

No smoking, no drinking, yet exercises regularly! A 70-year-old man dies from massive liver cancer—the culprit found in his belongings was a 'mold-infested thermos'

On the program 'Little Universe, Big Explosion,' gastroenterologist Dr. Chien Cheng-Hung shared this shocking clinical case. The man in his 70s was extremely health-conscious, maintaining regular routines, exercising consistently, and completely avoiding tobacco and alcohol. Yet, he was diagnosed with advanced liver cancer during a health screening, and his condition rapidly deteriorated, leading to his untimely death.

Later, while sorting through his belongings, his family opened the thermos he used daily for tea and water and discovered severe mold growth inside the container and on the lid's interior. Dr. Chien explained that the man had the habit of brewing tea in his thermos, and the dark tea color easily concealed mold spots, making them difficult to detect immediately. Drinking water from a moldy container over a long period ultimately became the invisible killer behind his fatal illness.

Hot water rinsing cannot remove toxins! Aflatoxins are highly heat-resistant—'thorough drying' is the key to mold prevention

Regarding common misconceptions about thermos cleaning, many people rinse their thermos with hot water after washing, believing high temperatures can sterilize. In response, 'Mother of Non-Toxic Living' Tan Dun-Tzu specifically warns that mold-produced toxins are extremely toxic and highly heat-resistant. For example, ochratoxin, which damages the kidneys, and aflatoxin, which harms the liver, cannot be removed by hot water rinsing alone.

Dr. Chien and Tan emphasize that the most common fatal mistake after cleaning a thermos is 'immediately closing the lid after washing due to fear of dust.' When the interior is not completely dry, this sealed, moist environment easily promotes rapid mold growth.

Experts share three essential tips for thermos hygiene and safety:

- Disassemble, clean, and thoroughly dry: After daily use, always remove silicone rings and rubber components from the lid and scrub them clean. After washing, they must be placed in a ventilated area to completely 'dry out.' - Keep the lid open when not in use: Whenever the thermos is not being used, keep the lid open to maintain internal dryness and ventilation. Dr. Chien admits that since learning about this case, he immediately opens his thermos lid whenever it's not in use to prevent moisture buildup. - Replace regularly: If mold spots that can't be cleaned, scratches, or prolonged use are present, it's recommended to replace the thermos immediately. Never compromise your health for the sake of saving money.
