Generally, carrier chickens contaminate the processing plant equipment to such an extent that negative chickens procell afterwards result in contaminated. meat. This study was performed to investigate the prevalence of Complliobacter jejuni in two chicken procelling plants. Altogether two hundred samples were collected from cloaca, carcasses, chilling water, and evis-cerationknives at different processing stages during the period of June to September 1987. The isolated organisms were tested for distribution of biotype, serotype. The results obtained were summarized as follows: 1. C. jejuni was isolated from 41(34.2%) of 120 chicken feces, 9(45.0%) of 20 carC888eS before chilling, 11(55.0%) of 20 carcasses after chilling, 12(60.0%) of 20 eviscerationlmives. The evilceration knives and chilling water were considered as major means of croll contamination. 2. In biotyping 82 isolates of C. jejuni, 64(78.1%) were cl888ified as biotype I, and 18(21.9%) belonged to biotype II. 3. In serotyping 82 isolates of C. jejuni, 64(78.1%) were identified as serotype LIO 37, and 18(21.9%) were untypable.
