"We were sufficiently freaked out," Amy Reed of Morrisville told WPVI-TV Wednesday.
Reed says they bought the organic grapes last week from the BJ's Wholesale Club in Langhorne. She had just started washing the grapes when something caught her eye.
"It was this black spider that kind of crawled up from inside the grapes. I was like 'Oh, that's just disgusting.' I could've eaten that spider," Reed said.
She quickly noticed it did not look like an everyday spider so she took a closer look.
"I just grabbed it with a pair of pliers, one of its legs, and I missed it the first time. It fell onto its back and that's when you could see the little red hourglass. I was like 'You've got to be kidding me,'" Reed said.
Reed then put the black widow in a bag and then in the freezer so to prove to anyone who heard her story that she wasn't making it up.
Officials from BJ's Wholesale Club have since been notified and are fully aware of the situation.
In response, they said in a statement, "We have inspected all other grapes and discovered no spiders or other insects. We are taking this matter extremely seriously and working with our vendor to take appropriate measures."
The distributor for the grapes, Welch's Organic Grapes, called the family directly to make sure they were OK and to tell them they've had this problem before because they don't use pesticides on their organic produce.
Meanwhile, Reed, who is an ICU physician at the Hospital of the University of Pennsylvania, says she is just happy she found the spider before the spider found her.
"My husband and I are both physicians, and if it had bit me - I had lung surgery a week ago - if all of sudden, I couldn't breathe and had chest pain, like 100 things could be causing that, none of those are a black widow spider bite," Reed said.
While only female black widow spiders are venomous, it's nearly impossible to differentiate between a male and a female.
The advice here is to always wash your produce thoroughly: organic or conventional.
