Salmonella serotype Montevideo infections associated with chicks--Idaho, Washington, and Oregon, spring 1995 and 1996
Abstract:
During 1995 and 1996, public health laboratories in Idaho, Washington, and Oregon identified clusters of infections with Salmonella serotype Montevideo. Epidemiologic investigations, including enhanced surveillance, of these clusters indicated association with exposure to chicks. This report summarizes the findings of these investigations, which suggest that handling chicks is a health risk, especially for children; consequently thorough handwashing is recommended after handling of chicks.
Insights
Salmonella Montevideo infections were linked to handling chicks in the Pacific Northwest. Thorough handwashing after contact with chicks is crucial to prevent illness, particularly in children.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- Clusters of Salmonella serotype Montevideo infections were identified in public health laboratories in Idaho, Washington, and Oregon during 1995-1996.
- Previous outbreaks have been associated with animal contact, highlighting the potential for zoonotic transmission.
Purpose of the Study:
- To investigate the source and transmission routes of Salmonella Montevideo outbreaks in the Pacific Northwest.
- To determine the association between chick exposure and human infections.
Main Methods:
- Enhanced surveillance for Salmonella infections was implemented in affected states.
- Epidemiologic investigations, including case interviews and environmental assessments, were conducted.
- Laboratory testing confirmed Salmonella serotype Montevideo in human and potential animal sources.
Main Results:
- Epidemiologic investigations revealed a strong association between the identified Salmonella Montevideo infections and exposure to chicks.
- Children were identified as a particularly vulnerable population for severe illness.
Conclusions:
- Handling chicks poses a significant public health risk due to potential Salmonella contamination.
- Strict adherence to hand hygiene practices, including thorough handwashing after handling chicks, is essential to prevent infections, especially among children.
