Yersinia enterocolitica gastroenteritis among infants exposed to chitterlings--Chicago, Illinois, 2002
Insights
A Yersinia enterocolitica outbreak in Chicago sickened nine infants. Health officials identified chitterlings (pork intestines) as the likely source, highlighting risks for infants during holiday seasons.
Area of Science:
- Public Health
- Infectious Diseases
- Pediatrics
Background:
- Infants are vulnerable to enteric infections.
- Yersinia enterocolitica is a significant bacterial pathogen.
- Chitterlings pose a risk for foodborne illness.
Purpose of the Study:
- To investigate a cluster of Yersinia enterocolitica infections in Chicago infants.
- To identify the source and transmission routes of the outbreak.
- To raise awareness among healthcare providers about Y. enterocolitica in infants.
Main Methods:
- Retrospective case series investigation.
- Epidemiological data collection and analysis.
- Public health surveillance and reporting.
Main Results:
- Nine infants aged <=1 year were infected with Yersinia enterocolitica.
- Infections occurred over a 10-week period during winter holidays.
- Exposure to chitterlings was identified as a likely risk factor.
Conclusions:
- Infants exposed to chitterlings are at risk for Yersinia enterocolitica infection.
- Yersinia enterocolitica should be considered in infant gastroenteritis cases, especially during holiday seasons.
- Healthcare providers need to be aware of this risk and advise families accordingly.
Abstract:
During December 2002-January 2003, the Chicago Department of Public Health (CDPH) investigated a cluster of Yersinia enterocolitica infections reported during a 10-week period among nine Chicago infants aged < or =1 year. This report summarizes the investigation of these cases and underscores the continuing risks for enteric infection among infants exposed to chitterlings (i.e., pork intestines), and the need for health-care providers to be aware of Y. enterocolitica as a cause of gastroenteritis, particularly in black children during traditional winter holiday celebrations.
