In late October 2007, a hunter in Northern California shot a black bear and brought the carcass home for a community feast the next day. At least 38 people ate a variety of dishes, some of which included bear meat which was not fully cooked. Within a week, people who had attended the event started getting sick with fever, chills, and muscle aches. Over the next few weeks, 30 people became ill. Based on the clinical symptoms and the history of a common meal of bear meat, a local physician suspected Trichinella infection was causing these illnesses and notified the county health officials.

The media has recently given attention to studies [G. Songer; Rodriguez-Palacios A, et al] that isolated a bacterium called Clostridium difficile from meats sold in grocery stores. C. difficile causes a severe colon infection and is generally acquired in hospitals and long-term care facilities. Although most of the cases of C. difficile infection are healthcare associated (80%), the other twenty percent of cases are acquired in the community – outside of healthcare settings. The cause(s) of these infections are still poorly understood. The recent studies question whether C. difficile in meats is a source of human infection.

CDC plays a vital role supporting state health departments, particularly with management of rare or lesser-known pathogens. Recently, CDC’s Division of Parasitic Diseases (DPD) was contacted by the Hawaii Department of Health (HI DOH) for advice regarding three cases of presumed Angiostrongylus cantonensis (AC) infection. AC, commonly called the rat lungworm, is a parasitic worm and the most common infectious cause of eosinophilic (a type of white cell) meningitis in humans worldwide.

A mysterious cluster of illnesses and deaths of unknown cause was recently reported in Baja California, a Mexican state that – as the Spanish translation suggests – is situated just below the California-Mexico border. Our shared border with Mexico fosters a mutual interest in epidemiologic events like this one — where time is of the essence and lives are at stake.

Malaria is preventable and treatable. However, each year 350–500 million cases of malaria occur worldwide, and more than a million people die, most of them young children in sub-Saharan Africa. In the U.S., about 1,500 people get malaria annually, almost all from traveling to countries where malaria is transmitted. In 2006, six people in the United States died from malaria.

CDC plays a vital role but public health happens at the local level thanks to the work of thousands of our state, territorial, tribal, city, and county public health professionals. So it is always a pleasure to meet with state epidemiologists, leaders in using epidemiologic data to guide public health practice and improve health. On January 29th, I met with the Executive Board of the Council of State and Territorial Epidemiologists [CSTE]. Needless to say, the conversation quickly strayed to the current Salmonella Typhimurium outbreak associated with peanut butter produced at a Peanut Corporation of America (PCA) facility in Blakely, Georgia. These conversations among colleagues are noteworthy for being quite frank.
