I am looking for microbiological criteria for food contact surfaces (re-usable plastic boxes to transport and storage fruits and vegetables) after cleaining and disinfection process. Specifically for Total Viable Count (TVC) and Enterobacteriaceae. I just found some recommendations from different researchers
Peter Snyder
TVC
-Clean: 2-10 CFU/cm2
-Aceptable: 10-100 CFU/ cm2
-Not aceptable >100 CFU/ cm2.
Forsythe and Hayes
TVC
-Excellent: < 1 CFU/cm2
-Good: 2-10 CFU/ cm2
Decision 2001/471/EC already derogated:
TVC
aceptable: 0-10 CFU/cm2;
Enterobacteria:
aceptable 0-1 CFU/cm2;
I would be very pleased if someone could help me out choosing the right values or giving to me reliable references
Many thanks in advance
