This case study focuses on whether E. coli O157:H7 should be added to Oregon's reportable disease list and the difficulties in dealing with an outbreak apparently linked to raw milk (1993).

Learning Objectives:

  • Discuss the process and criteria for placing a disease or condition on a state or national notifiable disease list;
  • List the categories of information that should be included in a surveillance instrument;
  • Summarize and interpret surveillance data; and
  • Recognize difficulties in balancing public health concerns with consumer and industry considerations in emerging issues.
