A Minnesota woman in her 80s died after she was infected with the salmonella strain suspected in a nationwide outbreak that has killed seven and sickened hundreds.State health officials said the woman lived in a nursing home. They have not released her name or the date of her death.

Most of the other deaths that salmonella may have contributed to also involved the elderly. Exact causes of death haven't been determined, but the Centers for Disease Control and Prevention says the salmonella may have contributed.

Almost 500 people have been sickened in the outbreak that has sparked a massive recall of peanut butter products supplied by Peanut Corp. of America in Georgia. Store owners rushed to remove about 200 products, including dog biscuits, cookies and energy bars, from their shelves."This is a very large extensive massive recall that happened in the grand scheme of things pretty quickly," Tom Skinner, of the US Centers for Disease Control and Prevention told the Associated Press.
