SpartanNash Co.

Nash Finch has filed a lawsuit alleging that "person or persons unknown--possibly employees--posted confidential information" about the company on a Yahoo! message board. The Edina, Minn.-based company's suit claims "breach of contract and misappropriation of trade secrets" and stipulates that if "the defendants turn out to be current or former employees, they would have violated Nash Finch's Code of Ethics and Business Conduct and Associate Handbook."

Nash Finch Company on Monday announced its completed acquisition of U Save Foods Inc. through a purchase of U Save's capital stock. Headquartered in Omaha, Neb., U Save Foods was a privately-held company with 14 supermarkets operating in Nebraska, Kansas and Colorado.
