"Aldi Supermarkets said it is pulling red grapes from its St Louis area stores after a black widow spider was found in a red grape container."
The headline to this story is somewhat misleading: St. Louis County Grocer Pulls Food from Shelves After Finding Deadly Spider
Later in the story there's this: "Experts at the St Louis Zoo say the widow’s bite is venomous and can make humans sick but is not lethal." In any event, the Black Widow spider has worked its way into bags of grapes coming from vineyards in California where they like to nestle in and make webs. Advice from this story is if you see a Black Widow in your produce or anywhere else, don't handle it but capture it and put it in a container.
Which leads to an unanswered question: "How do you capture a spider and get it into a container without handling it?"
