Czech tuzemák has again caught the attention of food regulators in Brussels. A chemical used to create the artificial rum flavor in the popular Czech liquor is suspected by the European Food Safety Authority of being carcinogenic. The chemical, called rum ether, is also used in candy and bake goods. The European Commission will evaluate the information and could ban the chemical from use in food and beverages across the EU. If that happens, Agriculture Minister Marian Jurečka will ask for an exception so that tuzemák can still be made.
