Employees at a Jennie-O Turkey Store processing plant in Willmar, Minnesota, were taken to a local hospital on Friday evening after a mystery illness caused about 30 workers to show symptoms such as vomiting and coughing. Reports said that seven ambulances and a bus were dispatched to the scene and about two dozen employees were hospitalized. Most were treated and released, but one employee was admitted and was in a stable condition, according to Pat Solheid, Jennie-O Turkey Store vice president of human resources and administration. Jennie-O is owned by Hormel Foods Corporation.
