Anyone who buys an expensive coffee machine or espresso machine usually does not think of a health hazard. The most affected are the expensive devices, where customers weigh themselves in the greatest security and would not have expected a risk to their health.
Lead in high-end espresso machines
It is questionable whether, based on this information, you can still enjoy an espresso at the Italian restaurant or in the café around the corner without hesitation. With a concentration of lead in espresso machines that is 100 times above the guideline value, the consumer is taking a high health risk. In addition to causing cancer, lead can also cause many other diseases. Even if the amount of lead released during the actual espresso brewing was not quite as high, the amount of lead released increased after decalcification. In order to keep an espresso machine running permanently and to remove the limescale from the tap water, owners regularly use a descaler and previously assumed that cleaning would make a positive contribution to maintaining the value of the machine, as well as to their health and, of course, the aromas in the coffee make espresso. The maximum value for proportionate heavy metals such as lead in devices used for the production of food is set in a guideline. However, this only serves as a recommendation for the manufacturer and is not legislation that would punish an infringement.
Clean new coffee and espresso machines
Before enjoying a new machine for the first time, it is advisable to carry out a thorough cleaning and run the machine idle. Since the lead was mainly released with acidic decalcifiers, consumers should avoid this form of cleaning and opt for natural limescale removal agents if decalcification is necessary. The manufacturers are required to reduce the release of lead in the affected devices to a minimum.
