Evaluation of the Washington State National Pharmaceutical Stockpile dispensing exercise, part II--dispensary site worker findings.

On January 24, 2002, the Washington State Department of Health, in collaboration with local and federal agencies, conducted an exercise of the Centers for Disease Control and Prevention's National Pharmaceutical Stockpile dispensing portion of the Washington State plan. This exercise included predrill planning, training, and the orchestration of services of more than 40 dispensary site workers. These workers provided education and post-exposure prophylaxis for over 230 patient volunteers in the aftermath of a simulated exposure to B. anthracis. This article discusses findings of a postdrill questionnaire completed by 90% of these dispensary site workers who provided triage, education, dispensary, security and other services during this exercise. In general, this dispensing drill promoted confidence in the worker participants and provided an opportunity for these participants to coordinate their activities. This mock bioterrorist preparedness exercise allowed worker participants and observers to review and evaluate the Washington State plan for dispensing the National Pharmaceutical Stockpile. This article is apparently the first published account of dispensary site workers' subjective impressions and quantitative analysis of their postdrill opinions following a simulated bioterrorist post-exposure chemoprophylaxis dispensing exercise.

Concurrent outbreaks of Shigella sonnei and enterotoxigenic Escherichia coli infections associated with parsley: implications for surveillance and control of foodborne illness.

In recent years, the globalization of the food supply and the development of extensive food distribution networks have increased the risk of foodborne disease outbreaks involving multiple states or countries. In particular, outbreaks associated with fresh produce have emerged as an important public health concern. During July and August 1998, eight restaurant-associated outbreaks of shigellosis caused by a common strain of Shigella sonnei occurred in the United States and Canada. The outbreak strain was characterized by unique pulsed-field gel electrophoresis patterns. Epidemiologic investigation determined that the illness was associated with the ingestion of parsley at four restaurants; at the other four restaurants, the majority of the people who contracted the illness ate parsley. Isolates from patrons in two unrelated restaurant-associated enterotoxigenic Escherichia coli (ETEC) outbreaks in Minnesota shared a common serotype and pulsed-field gel electrophoresis (PFGE) pattern. Parsley was the implicated or suspected source of both ETEC outbreaks. In each of the outbreak-associated restaurants, parsley was chopped, held at room temperature, and used as an ingredient or garnish for multiple dishes. Infected food workers at several restaurants may also have contributed to the propagation of the outbreak. The sources of parsley served in outbreak-associated restaurants were traced, and a 1,600-acre farm in Baja California, Mexico, was identified as a likely source of the parsley implicated in six of the seven Shigella outbreaks and as a possible source of the parsley implicated in the two ETEC outbreaks. Global food supplies and large distribution networks demand strengthened laboratory and epidemiologic capacity to enable state and local public health agencies to conduct foodborne disease surveillance and to promote effective responses to multistate outbreaks.

Evaluation of the Washington State National Pharmaceutical Stockpile dispensing exercise: Part I--Patient volunteer findings.

The Centers for Disease Control and Prevention's National Pharmaceutical Stockpile (NPS) program is designed to ensure the availability of life-saving antibiotics, other medical supplies, and equipment and their prompt delivery to the site of a disaster, including a possible bioterrorist incident, anywhere in the United States. On January 24, 2002, the Washington State Department of Health conducted an exercise, simulating a mass exposure to Bacillis anthracis, to test the NPS dispensing portion of the Washington State plan. This drill included the recruitment, education, and postexposure prophylaxis of over 230 volunteer patients. This article describes and discusses findings from an exit survey completed by these patient volunteers.
