Luxembourg hotels have begun advising travelers not to eat or drink in the back of carts on its taxi fleet. Locals are calling it the “hotchpotch of germs.” The scurrying carts are used by the town’s many professional taxi drivers to pick up fares in the snowy highlands. But once inside, travelers are advised to avoid touching the bags, so it’s unlikely they’re rubbing germs on the handles. Still, travelers should watch where they flush the toilet, as its innards, flushed by drivers in the townships, could carry travelers viruses. (The eggs of some dandelions, powdery flowers with seeds, could also add to the pollution of the area.) Other tests indicate that lurking in the area are strains of E. coli, bacteria not known to cause illness in other parts of the world. Last week an American woman, suffering an irregular heartbeat, was found to have cholera in Cyprus, also an area known for water-borne epidemics, in 2010, and yet another Typhoid-like illness spread last October and killed one person in Malta.
