UIC Receives USDA Grant to Educate AIDS Patients About Food Safety
August 24, 2009
Researchers at the University of Illinois at Chicago School of Public Health have received a three-year, $600,000 award from the U.S. Department of Agriculture to develop a better way to disseminate information to AIDS patients who are at high risk of developing infections from the foods they eat.
Nearly half a million people in the United States are living with AIDS, according to the Centers for Disease Control and Prevention.
AIDS patients whose immune systems have been severely suppressed by the HIV virus to a T-cell count below 200 cells per microliter are at risk of developing life-threatening infections from food-borne illnesses.
In addition to their compromised immune systems, people with AIDS may have low stomach acid, which is the first barrier against germs, said Mark Dworkin, UIC SPH associate professor of epidemiology and principal investigator of the study. Stomach acid normally kills most of the germs that enter the body through the mouth. For example, such patients can become infected with salmonella bacteria from eating fresh fruits and vegetables that are not washed properly.
Dworkin added that most people with AIDS are probably not aware that food safety recommendations for them may include heating lunchmeat. Listeria, a foodborne pathogen that has been attributed to eating lunchmeat and soft cheeses, can cause meningitis and sepsis in AIDS patients.
Other risks include:
The researchers will interview 300 AIDS patients in Chicago, New Orleans and Bayamón, Puerto Rico, to determine the biggest knowledge gaps in food safety.
"During the first wave of interviews, we'll ask questions about behavior and risk," Dworkin said. "Do they eat a lot of lunch meat? Do they eat pâté? Do they cook their own food? Do they go out to eat frequently?"
Using information gathered from those interviews, the researchers will create an entertaining and educational comic book that has the theme of a menu. The book will be disseminated at AIDS clinics in the three cities. Researchers will return a month later to assess patients' knowledge of food safety issues.
Researchers will also survey health care providers in the three cities to determine if they have food safety educational material for AIDS patients and to raise awareness about the new evidenced-based intervention.
Traditional food-borne disease surveillance does not take AIDS into account. It is unknown among the various food-borne outbreaks how many of these illnesses are occurring in AIDS patients.
Dworkin said the greatest risk for disease from food-borne pathogens is likely among the newly diagnosed AIDS patients who are not yet receiving anti-retroviral therapy; those who have resistant virus; and those who have other difficulties with their HIV medication and stay in the low AIDS range.
Dworkin has received two previous grants totaling $1.5 million from the USDA to create evidence-based educational materials for restaurant food handlers in Chicago and the surrounding suburbs.
