A recent seizure has put a new meaning behind the phrase “a killer pair of shoes.” On April 22nd, customs officials on the western border of Poland seized 32,000 pairs of flip-flops – plastic sandals with only a strap in the front – that were made of carcinogenic substances. The footwear had been imported from China for sale in the country.
The carcinogenic material in the shoes was originally detected by the border guards due to a strong odor coming from container. Tests at the Wrocław Customs Laboratory confirmed the presence of carcinogenic substances, which become active when exposed to heat. The shoes were shipped back to China before a single pair made it to the Polish market.
