BfR: Reusable cups pose health risks
The Federal Institute for Risk Assessment (BfR) reports this and points to a current risk assessment (Section Questions and Answers: "Use of customer-owned reusable cups for 'Coffee to go': pay attention to hygiene standards and materials").
Brought reusable cups, for example for "Coffee to go," are becoming increasingly popular in times of heightened awareness of sustainable lifestyles. The containers are usually made of glass, stainless steel, porcelain, or plastics, also in mixed forms. Behind the marketing claim of "natural" materials there are often additives like bamboo fibers and rice husks, typically embedded in melamine-formaldehyde resin (MFH) plastics.
The BfR warns that hot beverages in MFH can leach the chemicals melamine and formaldehyde from the container matrix. The BfR does not see any infectiological dangers with proper use (cleaning and drying after each filling). According to the BfR, reusable cups made of MFH should not be filled with hot, acidic liquids such as coffee, tea, or mulled wine.
