title: [The occurrence and survival of Campylobacter in sewage sludge].
abstract: Campylobacter was found only in raw sewage sludge samples of the high-rate municipal sewage treatment plant studied. Campylobacters were isolated from 28.6% of the sewage sludge samples of grit tank and primary settling tank. 40% of the settled activated sludge samples contained Campylobacter. Campylobacter was never found in digested sludge of a mean sludge age of more than 90 days. The survival times of Campylobacter in sewage sludge samples ranged between some hours and 10 days. Therefore a low risk of the spread of Campylobacter in the environment due to agricultural application of digested sewage sludge is assumed.
