Gail L. Daumit, Judith A. Hermann, Josef Coresh, and Neil R. Powe Differences between ethnic groups in use of cardiovascular procedures narrowed markedly once a serious illness developed and adequate insurance coverage was ensured. The disparity was eliminated in patients with previous Medicare insurance or a stronger indication for a procedure.
Lucian L. Leape, Lee H. Hilborne, Robert Bell, Caren Kamberg, and Robert H. Brook Although revascularization procedures are substantially underused, the rate of use did not vary by sex, ethnic group, or payer status among patients treated in hospitals that provide coronary artery bypass graft surgery and percutaneous transluminal coronary angioplasty. However, underuse was significantly greater in hospitals that do not provide these procedures, particularly among uninsured persons.

Sara H. Cody, M. Kathleen Glynn, Jeff A. Farrar, K. Lisa Cairns, Patricia M. Griffin, John Kobayashi, Murray Fyfe, Richard Hoffman, Arlene S. King, Jay H. Lewis, Balasubr Swaminathan, Raymond G. Bryant, and Duc J. Vugia In fall 1996, a small cluster of Escherichia coli O157:H7 infections was linked to unpasteurized apple juice. This study found that standard procedures at a plant that produces unpasteurized juices were inadequate to eliminate contamination with E. coli O157:H7. This outbreak showed that unpasteurized juices must be considered a potentially hazardous food.
Barbara L. Herwaldt, Michael J. Beach the Cyclospora Working Group* In spring 1996, an outbreak of cyclosporiasis associated with fresh Guatemalan raspberries occurred in the United States and Canada. In spring 1997, another outbreak took place. These outbreaks highlight the need for better understanding of the biology and epidemiology of Cyclospora cayetanensis and for stronger prevention and control measures to ensure the safety of produce that is eaten raw.

Editorials
Richard L. Kravitz The articles by Daumit and Leape and their colleagues in this issue indicate that health care access, quality, and equity are related. As we continue to strive to reduce ethnicity-based disparities in access to health care, we should not neglect the equally important issue of assuring that those services are delivered in an appropriate, timely, and effective manner.
Michael T. Osterholm In this issue, Herwaldt and colleagues conclude that the 1997 outbreak of raspberry-associated cyclosporiasis highlights the need for improved surveillance for foodborne illnesses. Although this conclusion may seem obvious, it is only a small piece of the public health effort needed to reduce the incidence of foodborne illness.
