The spider in question is the Brazilian Wandering Spider, and someone claimed they saw it in the store. This spider has a history of sneaking into Europe, usually hitching a ride with shipments of bananas headed for stores.
From TMZ:
The 4-inch, black and red spider apparently popped up at the Penny supermarket in Krems an der Donau, which is about 45 miles west of Vienna ... the store called authorities after Tuesday's sighting and the shop has been shuttered ever since.
It's super scary ... the spider is still on the loose despite an extensive search of the store, which included sealing all the banana crates.
The Brazilian Wandering Spider is featured in the Guinness Book of World Records as the world's most venomous arachnid ... and its bite can also cause hypothermia, blurred vision and convulsions, in addition to erections.
Stories about Australia's terrifying insects, especially those gruesome-looking spiders, appear to be never-ending.
Guess I'll be taking this country off my travel list...
