Sample Preparation
For indicator organisms (TC, EC, ETB, YM, XSA and XBC) - cut out standrardized sample (e.g 10 g or 25g), Place in sterile container, and add the appropriate volume of sterile diluent (e.g 90ml or 225ml of Buffered peptone water (BPW), maximum recovery Diluent (MRD), or 0.1% Peptone water). Homogenize and dilute accrordingly.
For pathogens (SL and LS)- Weigh 25g and dilute with 225ml sterile BPW, then homogenize.
Regulatory limits
Refer to codex Alimentarius and local regulatory bodies.
Processing notes
- Use 25g sample size for samples that absorb a large volume of diluent.
- User filter bags to minimize inclusion of sample particles during inoculation.
Animal feeds generally has high microbal load. For TC, plate using 10-3 (Figure 2) or 10-4 (Figure 3) dilution while using 10-1 or 10-2 for other indicator organisms.
Similar to other tests that rely on β-Glucuronidase activity to detect E.Coli, CompactDryTM EC cannot detect E.coli O157:H7 as an E.coli.
AZ LAB Co.,LTD is currently the official distributor of Nissui Compact Dry products in Vietnam with all the following criteria: Total Count (TC), E.coli and Colifrom (EC), Enterobacteriae (ETB), Vibrio parahaemolyticus (VP), Bacillus cereus (X-BC), Yeast & Mold (YM), Staphylococcus aureus (XSA), Enterococcus (ETC), Pseudomonas aeruginosa (PA), Salmonella (SL), and Listeria.
