A good cup of coffee jump starts a good day for many of us. But there’s no such thing as too much of a good thing. An excessive amount of coffee can hurt us fatally! For a 150-pound healthy man 70 cups, a day will do it in. There’s also the coffee percolator or maker.
Stovetop coffee percolators are made of aluminum and using a percolator continuously will result in aluminum poisoning!

Aluminum Poisoning

Too much aluminum intake might cause damage to the bloodstream. It will be in the way of iron intake, therefore, injuring metabolism. Overuse of an old percolator will cause aluminum poisoning. If you’re using uncoated aluminum, then the risks will go further up. A study shows the link between aluminum and Alzheimer’s disease.However, if the pot is aluminum and we heat acidic content such as tomato or coffee, percentages of aluminum increases steadily. As a result, it violates coffee machine safety.

Fire Safety

A few points how a coffee percolator may be the cause of fire –

  • Approximately 145000 coffee maker caused a fire by wire overheating in 3008 alone
  • In 1989 a number of coffee makers were recalled off the market due to the malfunctioning of the coffee maker’s thermostat.
  • Thermoplastic insulation may get damaged due to heat or torn away and can cause short-circuit fire

For these reasons in some cases, coffee machines are not safe.


After buying a new coffee pot many consumers taste some odd plastic taste that is not originated from the beans. There are traces of Byphenol A (BPA), an endocrine disruptor that could lead to reproductive issues as far as infertility and cancers which is one of major safety concerns of a coffee machine.
