State health officials say at least 40 cases of bleeding from rat poison have been confirmed in four counties since March. One 33-year-old woman died in July. The rat poison has been found in synthetic marijuana, also known as K-2 or spice. It isn’t known how or why the rat poison got into the products. At least 10 other states are dealing with a similar situation. There have been eight new cases in Wisconsin in just the last two weeks.
