Thousands of hot dogs spilled onto a highway in the US state of Pennsylvania after a lorry scraped another car, briefly bringing traffic on the road to a standstill.

Four people required medical attention following the incident on the Interstate 83 highway, but none of their injuries were life-threatening.

Brad Dauberman, a local fire chief who helped with the clean-up, said: “I can tell you personally, hot dogs are very slippery… I did not know that.”
