A Pennsylvania woman found quite an unpleasant surprise in a batch of organic grapes she had purchased.

NBC Philadelphia says that Amy Reed was shopping at the BJ’s Wholesale Club in Langhorne, PA  Monday evening when she bought the grapes. When Reed opened the grapes Tuesday, she was shocked to find a black widow spider crawling around.

Reed saw the spider before actually eating the grapes or giving them to her children.

Her husband, Hooman Noorchashm told NBC10 he and his wife contacted the store Wednesday morning, and said the store has been “very cooperative." Noorchashm said an official from BJ’s called the family, and told them the growers from California where the grapes came from said that black widows are a problem out there.

An official from BJ's told NBC 10

We are aware of the black widow spider a Member found in a pack of organic grapes at our Langhorne, PA location. 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.

Black Widow spiders are very poisonous and their bites can be harmful to humans though rarely fatal.
