BJ’s Wholesale Club Inc., the third-largest U.S. warehouse retailer, said a batch of mushrooms it recalled this week wasn’t contaminated with E. coli.

The news clears the name of Kaolin Farms in Kennett Square, Pennsylvania, the source of the mushrooms.

John Pia, co-owner of Kaolin Mushroom Farms, told The News-Journal on Wednesday he was convinced that all his products were safe and the testing would prove it.
