[Group cryptosporidiosis morbidity in children]
Insights
Cryptosporidiosis outbreaks in infants were linked to contaminated kefir. Oocysts were found in milk, suggesting farm contamination as the source, not kitchen staff.
Area of Science:
- Public Health
- Infectious Diseases
- Microbiology
Context:
- A cryptosporidiosis outbreak affected infants in a hospital and nursery school.
- Kefir produced in the nursery milk kitchen was identified as the transmission vehicle.
- No oocysts were detected in the milk kitchen personnel.
Purpose:
- To investigate the source and transmission route of a cryptosporidiosis outbreak.
- To identify the point of contamination in the food supply chain.
Summary:
- Thirteen cases of cryptosporidiosis occurred in infants linked to contaminated kefir.
- The contamination was traced back to milk, with oocysts found in milk sediments at a factory.
- This suggests the milk farm as the likely origin of the oocysts.
Impact:
- Highlights the risk of foodborne cryptosporidiosis in vulnerable populations.
- Emphasizes the importance of rigorous milk supply chain monitoring.
- Informs public health interventions to prevent future outbreaks.
Abstract:
The group morbidity with cryptosporidiosis (13 cases) was recorded in infants from a somatic hospital and a nursery school and also among unorganized groups. The factor of transmission was kefir prepared in the nursery milk kitchen. Cryptosporidian oocysts were not found in the personnel of the kitchen. It was supposed that the contamination of milk by oocysts occurred on milk farm. Single oocysts were found in milk sediments on the filter taken from a tank at a milk factory.
