Employees at a Hong Kong crisp factory got a nasty shock when they discovered a World War I-era grenade in a pile of potatoes imported from France. The mud-coated device was likely left in a trench 100 years ago.

A police bomb squad was called to the Calbee snacks factory in eastern Hong Kong after staff there found a hand grenade from the First World War inside a crate of French potatoes, police said.
Officers moved cars and piled sandbags around the 1-kilogram (2.2-pound) device before safely destroying it.
"The grenade was in an unstable condition because it had been previously discharged but failed to detonate," superintendent Wilfred Wong Ho-hon told reporters.
The grenade, thought to be a German model, was encased in mud and hidden in a shipment of potatoes imported from France. Hong Kong University military historian Dave Macri said the weapon was probably buried beneath a former battlefield some 100 years ago.
"If it was covered in mud, the grenade was likely to have been left behind, dropped by soldiers there during the war, or left there after it was thrown," he told the South China Morning Post.
"The ditch was then filled up and used as a growing field, and the explosive was tossed into the mix of harvested potatoes ... and sent to Hong Kong."
The discovery of wartime bombs or grenades is not uncommon in Hong Kong. During World War II, the city saw fierce battles between Japanese and British forces and was heavily bombed by the US and its allies.
Unexploded ordnance in Germany - a legacy of the Allied Forces
Over 50,000 people were evacuated from the northern city of Hanover in May 2017, so that bombs from World War II could be defused. Even 72 years after the war ended, unexploded bombs are still found across the country.

What is unexploded ordnance?
Unexploded ordnance (UXO or sometimes also abbreviated to UO), unexploded bombs (UXBs), or explosive remnants of war (ERW) are explosive weapons such as bombs, shells, grenades, land mines, naval mines and cluster munitions that did not explode when they were deployed. Unexploded ordnance still poses the risk of detonation, even decades after they were used or discarded.

Why does Germany have a bomb problem?
Between 1940 and 1945, US and British forces dropped 2.7 million tons of bombs on Europe. Half of those bombs targeted Germany. Experts estimate that close to a quarter of a million bombs did not explode due to technical faults. Thousands of these bombs are still hidden underground, sometimes a few meters down and sometimes just below the surface.

How big is the issue?
The industrial Ruhr area and the Lower Rhine region were heavily bombed, as were the cities of Dresden, Hamburg and Hanover. So this is where most of the unexploded ordnance is found. Bombs are usually unearthed during construction work or are discovered during the examination of historical aerial images. Experts say it could still take decades to clear all of the remaining unexploded ordnance.

What happens when an unexploded bomb is found?
When confronted with the discovery of an UXO, UO or a UXB, bomb disposal experts have to decide whether to defuse it or to carry out a controlled explosion. Many have lost their lives on the job. German authorities are under pressure to remove unexploded ordnance from populated areas. Experts argue that the bombs are becoming more dangerous as time goes by due to material fatigue.

How many bomb disposal experts have died?
Eleven bomb technicians have been killed in Germany since 2000, including three who died in a single explosion while trying to defuse a 1,000-pound bomb on the site of a popular flea market in Göttingen in 2010.

Which was the biggest evacuation?
A 1.8-ton bomb dropped by Britain’s Royal Air Force (RAF) was found in the city center of Augsburg on December 20, 2016. The find prompted a large-scale bomb disposal operation and consequently the evacuation of over 54,000 people on December 25. To date, this remains the biggest evacuation for the removal of World War II unexploded ordnance in Germany.

What’s the latest?
Authorities conducted another big bomb disposal operation in May 2017, with 50,000 residents in the northwestern city of Hanover forced to evacuate their homes. Thirteen unexploded ordnances from the 1940s were removed. Hanover was a frequent target of Allied bombing in the latter years of the war. On October 9, 1943, some 261,000 bombs were dropped on the city.
