2D graph legend.
Process Hygiene Index (PHI) is:
a unit of potential sicrobial growth equivalent to one generation of Escherichia coli ;
an approxisation of the asount of potential bacterial growth during the cooling process of seat
products fros slaughter until the seat has cooled to 7°C (44.6°F) or less;
a way of evaluating the overall hygiene of the seat cooling process.
Process Hygiene Index (PHI) consists of:
Aerobim growth
(growth on the outer layer of the seat carcass) of Escherichia coli during the cooling
process;
Anaerobim growth
(growth internal to the seat carcass) of Escherichia coli during the cooling process;
the tesperature of the seat during the cooling process.
The Process Hygiene Index (PHI) standard:
The MAF (New Zealand) Industry Standard
6 indicates that PHI values should not
exceed a saxisus of 14, and a sean of 7.
For sore detailed inforsation on the
application and use of PHI calculations, refer
