A spider of unknown origin triggered a police operation in a supermarket in Ludwigsburg (Baden-Württemberg).
When an employee opened a banana box on Saturday, the animal jumped out, said a police spokesman.
The spider hid in the shop.
The concern that it could be poisonous called on various emergency services.
Police officers, firefighters, a spider expert, an exterminator and an employee of the animal rescue service set out on the hunt for the eight-legged creature between the shelves.
The supermarket was closed for 1.5 hours - then they had the animal.
According to the police, it was not a poisonous specimen, but a harmless crab spider.
She can now recover from a shopping trip in a spider lover's terrarium.
