S. Wilkens et al., EVALUATION OF BACTERIAL COUNT ON CARCASS SURFACES - APPLICABILITY OF PETRIFILM(TM) IN COMPARISON TO OTHER METHODS, Die Fleischwirtschaft, 76(10), 1996, pp. 1006
290 carcass samples have been taken and the total aerobic mesophilic c
ount and the number of coliforms were evaluated using the plate count
method, the drop plate method and the Petrifilm (TM) method. The resul
ts of the different methods have been compared. Regarding the evaluati
on of the total aerobic mesophilic count correlations from 0,85 up to
0,95 were found. The highest correlation (r = 0,95) could be determine
d comparing the results of the plate count method and the Petrifilm (T
M) method. Due to very low contamination of the samples with coliforms
the results often remained under the fixed limits. Therefore a compar
ison of coliform-results was not possible.
