The world's longest hot dog is a world record dating back to at least 2001. The record supposedly was most recently beaten in October 2017 in the town of Flensburg in Germany, where a group manufactured and served a U-shaped hot dog with a length of 218.7 metres (718 ft). However this attempt was not a valid one apparently, as it consisted of multiple pieces of bread and sausages instead of one of each.[1] In the official page of Guinness World Records the current holder of the record is Novex S.A. done in Paraguay in July 2011.[2][3]
In Chile, the city of Talca made an unofficial attempt where they tried the longest "completo", a Chilean upgraded version of the hot dog, where they reached over 450 metres by placing 2400 completos in a row. Sadly it became a meme in the country as it wasn't a single unit.[4]
