适用范围:1 Dip-slide method
1.1 This method describes dip slide procedures that use two types of agar to test the presence of commensal bacteria and coliforms (gram negative). This procedure is suitable when a manufacturer requires a simple test to screen finished filling material hygiene.
1.2 This method cannot be used to test the presence of sulfite-reducing clostrides (gram positive) and salmonella (gram negative).
2 Selective medium and count plate method
This method describes procedures that use different types of medium to verify the presence and quantity of:
—mesophilic aerobic bacteria (see 6.4);
—faecal streptococci (see 6.5);
—sulfite-reducing clostridium (see 6.6);
—salmonella (see 6.7).
This method, used for both raw and finished materials, gives more complete and specific information on the control of the microbiological state of the filling material than the dip slide method.
