CHATHAM, Mich. (AP) — A Michigan family found a black widow spider inside a bag of grapes bought at a Wal-Mart store. Gloria Johnson says the spider crawled out of the bag after her mother washed the grapes in the sink. The 11-year-old from the Upper Peninsula community of Chatham [tells WLUC-TV](http://bit.ly/1jFo1DC) she saw the red hourglass shape on the bottom of the spider, then put it in a jar of alcohol and killed it. Gloria says her 3-year-old sister already had eaten some of the black seedless grapes before they noticed the spider. She wasn't hurt. In a statement, Bentonville, Ark.-based Wal-Mart Stores Inc. apologizes to the Johnson family and says its "Marquette branch has looked through the other merchandise in the store and did not find any other spiders."
