Abstract
Anaerobic bacterial, clostridial, and Clostridium perfringens spores were enumerated in raw goose liver samples taken after evisceration of the birds (EB) in the slaughterhouse and after removal of blood vessels from the liver (RBVL) in the cannery. The samples taken after RBVL had significantly higher (P < 0.05) spore counts than did those taken after EB, indicating contamination of livers during processing. The number of C. perfringens spores was one log cycle higher in the samples taken after RBVL than in those taken after EB (P < 0.05). The confirmation of C. perfringens according to the profiles of Rapid ID 32 A tests was carried out by means of the ATB Plus computer program. With an identification percentage of 99.9 and a T-value of 0.65, the suspect colonies proved to be C. perfringens. Therefore, the importance of an appropriate cleaning and sanitation program and of personnel hygiene should be emphasized in the industry.
