A Taiwanese man died from severe lead poisoning and pneumonia after using thesame rusty thermos for over a decade, despite visible signs of corrosion.

Doctors discovered the man had regularly stored acidic drinks like coffee, tea and juice in the degraded container, leading to heavy metal contamination. His weakened immune system made him vulnerable to a fatal lung infection.

Health experts urge the public to use food-safe, rust-resistant containers preferably 304 stainless steel avoid storing acidic beverages long-term, clean them properly and replace them every two to three years.
