ZAGREB, Croatia—Traces of a cleaning agent have been found in the fizzy drink that was served to a man in Croatia who was later hospitalized with a throat injury, triggering a nationwide alarm, police said Thursday.
An analysis of the bottle and glass served to the man at a cafe last weekend in the northern port of Rijeka showed that the contents of both included a highly alkaline substance. But it remains unclear how it got there, and other similar drinks that were tested were problem-free, police said in a statement.
