Redback spiders have been found in bags of grapes being sold at two different Coles supermarkets on either side of the Queensland-New South Wales border, Report informs referring to 9News.
In purchases made February 10, one of the spiders was found in a bag bought at Runaway Bay on the Gold Coast and the other in a bag from Tweed City, just south of the border.
Retired policeman Andrew Bell told nine.com.au his daughter was eating grapes when she came across the "very much alive" spider.
"She was just munching away at them, and she just saw this redback," he said.
"The last thing you're expecting is a goddamn redback in the grapes."
Bell was concerned about what would happen if a child came across a venomous spider like a redback while they were eating.
While venomous, redback spiders rarely bite humans.
An initial bite may not be particularly painful, but will develop over the next hour or two.
But the venom of a redback can kill, with young children especially at risk.
If bitten, people should immediately seek medical aid, apply ice packs and stay calm.
Tourniquets and restrictive bandages should not be used.
