Unpasteurized Milk
Likely Source of Campylobacter Outbreak Fresh cheese
produced from unpasteurized milk may have led to Campylobacter jejuni infections in Publish date: Jan 5, 2009 Source of Article: http://www.modernmedicine.com/modernmedicine/Modern+Medicine+Now/Unpasteurized-Milk-Likely-Source-of-iCampylobacter/ArticleNewsFeed/Article/detail/573792?contextCategoryId=40152 MONDAY, Jan. 5 (HealthDay
News) -- An outbreak of Campylobacter jejuni
that occurred in Kansas during 2007 was likely due to the consumption of
fresh cheese produced from unpasteurized milk, according to a report in the
Jan. 2 issue of the U.S. Centers for Disease Control and Prevention's Morbidity
and Mortality Weekly Report. D. Charles Hunt, of the Kansas
Department of Health and Environment, and colleagues reported the results of
an investigation immediately following the C. jejuni
outbreak. The outbreak occurred within an isolated community of approximately
150 individuals, following a community fair during which fresh cheese was
made from local unpasteurized milk. A total of 87 percent of the community
completed the questionnaire, nearly half of which (52 percent) met the case
definition for C. jejuni infection. Although
none of the respondents reported diarrhea symptoms prior to the fair, 97
percent and 27 percent reported watery or bloody diarrhea, respectively,
after the fair, the investigators found. Those consuming the fresh cheese
made at the fair had a 13.9 relative risk of illness, the report indicates. A
total of 66 percent of persons who consumed the fresh cheese had C. jejuni symptoms. C. jejuni
was isolated from three patient specimens, but was not found in leftover
cheese or milk samples. Although unpasteurized milk was not
confirmed as the source of infection, an accompanying editorial note asserts
that "to prevent milkborne infections,
unpasteurized milk and unpasteurized milk products should not be
consumed." |
