title: [Detection of a Disease Cluster by the Health Authorities of Stendal District due to Campylobacter jejuni in a Nursery After the Consumption of Raw Milk].
abstract: A notification from a laboratory concerning the detection of Campylobacter jejuni in a 6-year-old boy initiated the investigation carried out by the health authorities from Stendal district, in order to explain the morbidity rate caused by the germ. The day after the boy's pediatrician informed about a visit to a farm, which was confirmed by the head of the nursery. She told the health authorities about the consumption of raw milk during their visit at the farm.The following days more children fell sick. Within 10 days the total number of diseased children was 21. The health authorities asked for stool samples of the diseased children, nursery nurses and the head of the farm since raw milk presents a potential cause of infection. The health authorities together with the Saxony-Anhalt State Office for Consumer Protection conducted a retrospective cohort study. The aim was to explain the association between the exposure from raw milk consumption and the occurrence of the disease from C. jejuni. Based on a questionnaire data about the food and milk intake at the nursery and at home and about the trip to the farm were collected. 91% of the children's cohort and 86% of the adults' cohort were captured.The exposed group at risk showed a higher risk of falling ill than the group, which was not exposed. The risk factor raw milk explained the difference. Furthermore, the analysis of milk samples taken by the district veterinary office from 2 cows and from the farm's tank was able to detect the germs. The correlation of the illness, the consumption of raw milk, the detection of C. jejuni in the samples taken from the children and the samples taken from the cows was evident. Based on the case the health authorities recommended that heads of nurseries as well as heads of dairy farming in the district of Stendal needed to be advised on raw milk. Nurseries are still allowed to take trips to farms. However, raw animal derivates including milk must not be consumed.
