Abstract
An investigation of the incidence and types of clostridia was carried out as part of a bacteriological examination of poultry carcasses and plant swabs. From 19 per cent to 35 per cent of chicken carcasses from four processing plants were contaminated with clostridia in the “total” differential reinforced clostridial medium count whereas 27–5 per cent to 83–5 per cent were contaminated with clostridial spores. Swabs of equipment and personnel (hands and aprons) in three of the plants showed that from 15 per cent to 75 per cent of the samples were positive for “ total” clostridia, and from 33 per cent to 85 per cent positive for clostridial spores. Clostridium welchii was recovered from all poultry plants but the incidence varied widely between the four plants sampled. The organisms isolated were Cl. bifermentans, Cl. histolyticum, Cl. butyricum, Cl. sporogenes and Cl. welchii. The majority of Cl. welchii isolates were from spore counts.Keywords
